The Pigeon Forge Mill , commonly called the Old Mill , is a historic gristmill in the U.S. city of Pigeon Forge, Tennessee . Located along the West Fork of the Little Pigeon River , the mill complex currently consists of a millhouse, breastshot wheel , and milldam, all of which are operative. The mill is the only structure in Pigeon Forge listed on the National Register of Historic Places .
139-500: Now a souvenir shop and restaurant, the Pigeon Forge Mill was once part of a small industrial complex established by local businessman Isaac Love (1783–1854) that included the iron forge for which the city was named. The mill was initially used to grind grain— mainly corn, wheat, and oats— for local farmers. During the U.S. Civil War (1861–1865), the mill powered several looms which produced cloth for
278-483: A Union supporter— installed looms in the mill to furnish uniforms for local Union volunteers (Trotter's son, William, commanded a company at the Battle of Fort Sanders in late 1863). After the war, Trotter expanded the mill, most notably adding a 60-rpm, 30-horsepower wooden wheel (the current breastshot wheel was a later addition), and establishing a sawmill at the site. Trotter's son, George, dismantled and sold
417-522: A crucial role pollinating plants and aiding in the decomposition of wood. The firefly Photinus carolinus , whose synchronized flashing light displays occur in mid-June, is native to the Great Smoky Mountains with a population epicenter near Elkmont, Tennessee . This firefly is sometimes referred to as a "celebrity insect" due to the large numbers of visitors who come to view its light displays. The Great Smoky Mountains National Park
556-642: A few quarries. In France, millstones from Cap d'Agde supplied Languedoc and Provence ; further north, quarries from the Massif Central ( Volvic ) supplied a vast territory stretching from Aquitaine to the Helvetic valleys ; finally, from the Saône valley to the German border, millstones came mainly from Eifel quarries ( Mayen ). In Europe as a whole, the hand mill remained the main milling method until
695-516: A given region. Some examples feature flatter wheels, with a much reduced taper, which reduces the stone mass. The speed of rotation became higher, providing a greater gyroscopic effect , but also requiring the installation of a system of claws fixed with molten lead on the upper side of the movable wheel, to hold it in place around the pivot. Romanization led to the widespread use of hand mills, which were perfected in terms of volume by increasing diameter and reducing height and weight. The profile of
834-471: A hard envelope such as a shell or bone is broken open to recover its contents, in this case, the aim is to reduce a much softer material to a powder or paste. Depending on the place and time, millstones were used for "dry" grinding: in the manufacture of flour , sugar , or spices , but also for the preparation of kaolinite , cement , phosphate , lime , enamel , fertilizer , and other minerals . The milling operation can also be carried out "wet", as in
973-478: A horizontal axis rotating around a vertical pivot (1, columella ). This pivot rests on a short stone column ( milliarium ) at the center of a large hemispherical mortar (4). The lying millstone is a stone vat (4, mortarium ) whose walls follow the external profile of the two common millstones. The orbs can move in a circular motion inside the mortarium , and are set in motion by the action of two wooden handles (2, modioli ). Wooden wedges ( orbiculi ) inserted between
1112-477: A key role in Mexican cuisine . Dry grinding is possible, but very few recipes are produced in this way: roasted coffee , roasted corn or beans , salt , sugar loaves, and cocoa are ground into powder. But most preparations require grinding with water. Fruits are ground into juices, beans or boiled vegetables, ingredients are added to various spicy sauces and, above all, corn is used to make the tortillas that form
1251-438: A large flat sandstone rock (for its abrasive qualities), used with a top stone, known as a "muller", "pounder", or pestle . The Aboriginal peoples of the present state of Victoria used grinding stones to crush roots, bulbs, tubers , and berries, as well as insects, small mammals, and reptiles before cooking them. Careful examination of Paleolithic grinders ( pebbles , wheels , mortar and pestle, etc.) enables us to determine
1390-708: A long ridge to the top of Brier Lick Knob at the Tennessee-North Carolina state line. The trail then roughly follows the crest of the range and the state line for its remainder in the park, rarely dropping below 5,000 feet (1,500 m). Kuwohi is the highest point along the entire trail. Other notable summits that the AT traverses include Thunderhead Mountain , Silers Bald , Mount Collins , Newfound Gap, Mount Kephart , Charlies Bunion , Mount Sequoyah , Mount Chapman , Mount Guyot , Old Black , and Mount Cammerer . A total of 12 trail shelters are located along
1529-535: A low density of food. Four protected fish species–the smoky madtom , yellowfin madtom , spotfin chub , and duskytail darter –are found in the park. Other prominent fish species include the American gizzard shad , lamoetra appendix , longnose gar , and mountain brook lamprey . More than 9,000 species of insects have been documented in the park. The most abundant insect groups include butterflies, moths, beetles, flies, wasps, bees, and ants. These insects serve

#17327876006831668-525: A new gesture, that of grinding from front to back, with both hands, which implies a new posture for the body, kneeling in front of the millstone. The appearance of large, asymmetrical, shaped millstones ( Mureybet , Sheikh Hassan, circa 10,000 BP) led to the "saddle-shaped" millstones still known today as the metate . At the Tell Abu Hureyra archaeological site, as early as the 8th millennium BC, women's skeletons show traces of osteoarthritis in
1807-486: A post office for the community that had developed around the complex, giving it the name "Pigeon Forge." Preston operated the Pigeon Forge iron works under the name "Sweden Furnace" until 1849, when he sold the mill and furnace to local businessman John Sevier Trotter (1807–1884). By 1856, Trotter was producing two tons of bar iron annually at the Pigeon Forge furnace. During the U.S. Civil War, Trotter—
1946-669: A powerful 80-foot (24 m) waterfall. In addition to day hiking, the national park offers opportunities for backpacking and camping . Camping is allowed only in designated camping areas and shelters. There are three shelters in the park that are not located on the Appalachian Trail. The Kephart Shelter is located at the terminus of the Kephart Prong Trail which begins upstream of the Collins Creek Picnic Area. The shelter, situated along
2085-472: A practice that persisted in some villages until the mid-20th century. The use of metal tools, probably inherited from building stonemasons, made it possible to use the hardest basalts, resulting in millstones with a lifespan of over thirty years. While the manufacture of apod millstones from blocks of stone naturally polished in a riverbed was once within the reach of many farmers, the production of tripode metates requires specialized craftsmanship. Grinding plays
2224-470: A significant portion of their income from tourism associated with the park. The park features three main entrances, located in Gatlinburg, Cherokee, and Townsend. Entrance into the park is free, while there is a fee for parking. U.S. Route 441 (US 441, Newfound Gap Road) is the main road through the park, and runs between Cherokee and Gatlinburg. The Gatlinburg entrance to the park is the busiest, and
2363-436: A slight gap is maintained between the two millstones. The running wheel pivots around a wooden axle embedded in the standing wheel, and it is thanks to its suspension on this axle that the gap between the two wheels is ensured. This type of millstone could be powered either by two or four men, or by animal rides, hence its name mola asinaria , literally "donkey mill". An example of this type of millstone can be found as early as
2502-431: A stationary base with a convex rim known as the bedstone (or nether millstone ) and a concave -rimmed runner stone that rotates. The movement of the runner on top of the bedstone creates a "scissoring" action that grinds grain trapped between the stones. Millstones are constructed so that their shape and configuration help to channel ground flour to the outer edges of the mechanism for collection. The runner stone
2641-461: A three-lobed feed opening. The more sharply tapered inner surfaces of the millstones ensured that the grains flowed more quickly under the effect of gravity, but the quality of the flour obtained remained mediocre. On the other hand, the effort required to operate the current millstone is considerable. The profile of the millstones makes them more difficult to cut, imposes a standardization of the millstones, and explains their diffusion and maintenance in
2780-854: A tributary of the Oconaluftee River can accommodate 14 people. Laurel Gap Shelter is one of the more remote shelters in the park. Situated in a beech forest swag between Balsam High Top and Big Cataloochee Mountain, the Laurel Gap Shelter can accommodate up to 14 people per night. This shelter is a popular base camp for peakbaggers exploring the heart of the Smokies wilderness. Millstone Millstones or mill stones are stones used in gristmills , used for triturating , crushing or, more specifically, grinding wheat or other grains. They are sometimes referred to as grindstones or grinding stones . Millstones come in pairs:
2919-439: A two-handed wheel, called a " mano ", whose size generally exceeds the width of the millstone and which is driven in an alternating rectilinear motion. On tripod wheels, one of the legs is slightly higher than the other two, giving the whole unit an inclination, with the user standing in front of the highest part. The manufacture of millstones was essentially a male occupation. In pre-Hispanic times, millers used only stone tools,
SECTION 20
#17327876006833058-400: Is Cades Cove , a broad, flat plain situated between the main range and some of the foothills. Other major valleys include The Sugarlands , Greenbrier , Ocanaluftee , Cataloochee , Elkmont , Tremont , and Deep Creek. These valleys are among the most accessible areas of the park, and are often used as reference points for major areas within the park. The Great Smoky Mountains National Park
3197-490: Is 5b with an average annual extreme minimum temperature of −14.3 °F (−25.7 °C). Ascending the mountains is comparable to a trip from Tennessee to Canada. The humid, subtropical air mass typically in place over the Smoky Mountains, coupled with orographic lift , produces large amounts of precipitation. Annual precipitation amounts range from 50–80 in (1,300–2,000 mm), with heavy winter snowfall in
3336-681: Is a major tourist attraction in the region. It has been the most visited national park for many years, with over 14.1 million recreational visitors (tourists) in 2021. The recreational figure represents nearly twice as many tourists as the Grand Canyon , which received nearly 6 million visitors the same year. Surrounding towns—notably Gatlinburg , Pigeon Forge , Sevierville , and Townsend in Tennessee, and Cherokee , Sylva , Maggie Valley , and Bryson City in North Carolina—receive
3475-732: Is also the southern terminus of the Great Smoky Mountains Parkway , a highway which connects the park to Pigeon Forge, Sevierville, and Interstate 40 to the north. The two main visitor centers inside the park are the Sugarlands Visitors' Center near the Gatlinburg entrance and the Oconaluftee Visitor Center near the Cherokee entrance. These visitor centers also contain ranger stations, and provide exhibits on wildlife, geology, and
3614-558: Is found only in the Smokies. The imitator salamander is found only in the Smokies and the nearby Plott Balsams and Great Balsam Mountains . Two other species—the southern gray-cheeked salamander and the southern Appalachian salamander —occur only in the general region. Other species include the shovelnose salamander , blackbelly salamander , eastern red-spotted newt , and spotted dusky salamander . The hellbender inhabits swift streams, and can grow to 29 inches (74 cm) in length. A total of 14 frog and toad species found within
3753-501: Is home to 65 species of mammals, over 240 species of birds, 43 species of amphibians, 67 species of fish, 40 species of reptiles, and 43 species of amphibians. The American black bear is perhaps the best known animal that resides within the Great Smoky Mountains National Park, and has come to symbolize wildlife in the park, frequently appearing on the covers of the park's literature. The range has
3892-410: Is home to diverse species such as coneflower, skunk goldenrod, Rugels ragwort , bloodroot , hydrangea, and several species of grasses and ferns. A unique community is the beech gap, or beech orchard. Beech gaps consist of high mountain gaps that have been monopolized by beech trees. The beech trees are often twisted and contorted by the high winds that occur in these gaps. Why other tree types such as

The Little Tennessee River runs along the southwestern border of the park, which is impounded by Chilhowee Dam , Calderwood Dam , Cheoah Dam , and Fontana Dam along the boundary. The Pigeon River flows through a deep gorge near the eastern boundary of
4587-496: Is located within portions of Blount , Sevier , and Cocke Counties in Tennessee, and Swain and Haywood Counties in North Carolina. The park borders an Indian reservation to the south that is home to the Eastern Band of Cherokee Indians , a federally-recognized tribe who are descended from a small group of Cherokee who evaded the forced migration of the Cherokee people to present-day Oklahoma . The town of Gatlinburg
4726-405: Is similar to the moist adiabatic lapse rate of 3.3 °F (1.8 °C) per 1,000 ft (300 m), while the smaller difference between low temperatures is the result of frequent temperature inversions developing in the morning, most often in autumn. Strong damaging winds of 80–100 mph (130–160 km/h) or higher occur a few times each year around the Smoky Mountains, mainly during
4865-496: Is supported by a cross-shaped metal piece ( millrind or rynd) fixed to a "mace head" topping the main shaft or spindle leading to the driving mechanism of the mill ( wind , water (including tide ), or other means). Often referred to as the "oldest industry", the use of the millstone is inextricably linked to human history. Integrated into food processes since the Upper Palaeolithic , its use remained constant until
5004-538: Is the most biologically diverse national park in the United States. About 19,000 species of organisms are known to live in the park, and scientists estimate that as many as 80,000 to 100,000 additional species may also be present. The land now protected by the park became a refuge for plants and animals that were displaced during the Last Glacial Period . The immense biodiversity is also supported by
5143-411: Is the only remaining wild cat species, although sightings of cougars , which once thrived in the area, are still occasionally reported. Raccoons , which are the state wild animal of Tennessee, are plentiful in the park. The Virginia opossum , the only marsupial in North America, is found in the park. The coyote is not believed to be native to the range but has moved into the area in recent years and
5282-588: Is treated as a native species. Two species of fox, the red fox and the gray fox , are found within the Smokies, with the former being documented at all elevations. An attempt to reintroduce red wolves into the park in 1991 failed drastically, forcing the U.S. Fish and Wildlife Service to remove the wolves from the area in 1998. These wolves were relocated to the Alligator River National Wildlife Refuge in North Carolina. North American river otters were reintroduced to
5421-493: Is usually rectangular, sometimes oval, with a central hopper parallel to the long sides, designed to receive the grain to be ground. The mill is capped by a horizontal axle attached to a pivot (1) on one side of the table, the other end being operated by a worker who moves the lever (2) back and forth horizontally. The Olynthus mill thus shows the beginnings of mechanization, with millers now standing on their feet, making work easier. This type of mill certainly appeared as early as
5560-533: The 2016 Great Smoky Mountains wildfires . Damaging winds can also be generated by strong thunderstorms , with tornadoes and strong thunderstorm complexes (also known as mesoscale convective systems ) occasionally affecting the Smoky Mountains. The park is affected by air pollution because of increased development nearby. In a 2004 report by the National Parks Conservation Association , Great Smoky Mountains National Park

Different stones were adapted for grinding different things and varied according to location. One important use was for foods, in particular to grind seeds to make bread, but stones were also adapted for grinding specific types of starchy nuts, ochres for artwork, plant fibres for string, or plants for use in bush medicine , and are still used today. The Australian grindstones usually comprise

5838-592: The Alleghenian orogeny that created the Appalachian range. During the Mesozoic era rapid erosion of softer sedimentary rocks re-exposed the older Ocoee Supergroup formations. Around 20,000 years ago, subarctic glaciers advanced southward across North America, and although they never reached the Smokies, the advancing glaciers led to colder mean annual temperatures and an increase in precipitation throughout
5977-966: The Classical era , used to grind ore in the Laurion mines , although it did not overtake the less efficient reciprocating millstone. Despite its qualities, it didn't really spread throughout the Roman world until later. They were found throughout the Mediterranean basin , but never in very large numbers, except in Italy. Their very high cost - 1,250 denarii in the Late Roman period, compared with 250 denarii for hand millstones - meant that they were only used by millers and bakers. In Gaul , millstones are known from Lyon , Saint-Raphaël , Paris , Amiens and Clermont-Ferrand , all fashioned from basalt from
6116-608: The Gravettian period onwards (circa 29,000 years), this equipment became more diversified, with the appearance of new types of tools such as millstones and pestle grinders. At the end of the Palaeolithic , millstones from Wadi Kubbaniya (Middle East, 19,000 B.C.) were involved in dietary processes and associated with residues of tuberous plants, which were known to require grinding before consumption, either to extract their toxins ( Cyperus rotundus , nutsedge), or to remove
6255-544: The Kebarian ( Ohalo II , 19,000 BC). As tools improved, the material was increasingly finely ground, but only when it became a real powder could we speak of grinding. Thus, the men of the European Upper Paleolithic were already dissociating grinding and milling , as attested by the appearance at this time of the first grinding slabs used with grinders or millstones. While there is no evidence of
6394-583: The Kebarian and Natufian periods. It gradually evolved into the heavy, generally wooden, thrown pestle. This type of equipment is still used today in many regions, such as in Ethiopia for milling millet. The appearance of flat, elongated millstones in the Natoufian period ( Abu Hureïra on the Euphrates ) dates back to the 9th millennium BC. They feature larger active surfaces and mark the emergence of
6533-827: The Maddron Bald Trail (between Gatlinburg and Cosby) is an accessible old-growth forest with some of the oldest and tallest trees in the entire range. Over 130 species of trees are found among the canopies of the cove hardwood forests in the Smokies. The dominant species include yellow birch ( Betula alleghaniensis ), basswood ( Tilia americana ), yellow buckeye ( Aesculus flava ), tulip tree ( Liriodendron tulipifera ; commonly called "tulip poplar"), silverbells ( Halesia carolina ), sugar maple ( Acer saccharum ), cucumber magnolia ( Magnolia acuminata ), shagbark hickory ( Carya ovata ), Carolina hemlock ( Tsuga caroliniana ) and eastern hemlock ( Tsuga canadensis ). The American chestnut ( Castanea dentata ), which
6672-580: The Mesolithic and Neolithic eras, with the domestication of plants, much larger, fully formed grinding, pounding, and milling equipment appeared. From the Natufian onwards, several types of millstones can be found side by side, such as the deep "trough-shaped" millstone or the flat millstone, indicating a specialization of their function. In the Near East , the pestle-grinder began to be developed in
6811-472: The North American beaver , woodchucks , chipmunks , two species of squirrel and skunk , and the endangered northern flying squirrel . 12 species of bats, including the endangered Indiana bat and Rafinesque's big-eared bat , are found within the park. Other mammals include the white-tailed deer , the population of which drastically expanded with the creation of the national park. The bobcat

The other venomous snake, the copperhead , is typically found at lower elevations. Both of these snakes are pit vipers . The eastern box turtle , which is the state reptile of North Carolina and Tennessee, is the most common turtle in the park, and is mostly terrestrial, but is usually found near waterways. Important lizards found within

In this system, the olives are not crushed under the millstone, but between the millstone and the sides of the vat. As in the previous model, a gap was maintained between the two millstones. The resistance offered by the fruit forces the stone half-spheres to turn slightly on their axis; the two movements combine and

In the Olynthus mill, the nether millstone(4) is rectangular, resting on a table (5); it measures between 0.42 m and 0.65 m in length, 0.36 m to 0.54 m in width and 0.08 to 0.25 m in thickness. The grinder, which forms the upper millstone (common millstone (3)),
8201-589: The Greek world was confirmed by the discovery, in 1967, of 22 hopper mills in the cargo of a ship wrecked off Kyrenia , dated to the end of the 4th century BC. Increasing demand undoubtedly led to standardization in manufacturing and specialization of production centers. For example, flat Argolidian millstones, made of andesite and rhyolite , were produced from local quarries ( Isthmus of Corinth , Saronic Gulf ), while grinders came from more distant quarries (islands of Nysiros , Milos ).

9869-671: The center of the park on its route from Georgia to Maine . With 13 million visitors in 2023, the Great Smoky Mountains National Park is the most visited national park in the United States. The park encompasses 522,419 acres (816.28 sq mi; 211,415.47 ha; 2,114.15 km ), making it one of the largest protected areas in the eastern United States. The main park entrances are located along U.S. Highway 441 ( Newfound Gap Road ) in Gatlinburg, Tennessee , and Cherokee, North Carolina , and also in Townsend, Tennessee . The park
10008-419: The city would eventually be named. Taking advantage of a Tennessee state law that allowed tax incentives for the creation of iron works on unfarmable land, Love acquired over 7,000 acres (2,800 ha) of the surrounding country. Love mined brown hematite ore in the hills northeast of the forge, and transported the ore to the forge using ox-drawn wagons. The forge included a bloomery furnace which converted
10147-613: The composition of De agri cultura , around 160 BC. Several types of mills can be identified in Europe, depending on the morphology of the millstones used in these manually operated rotary mills. The Celtic mill is made up of massive millstones, with a conical external profile and virtually flat active stone surfaces. In Dacia , between the 1st century B.C. and the 1st century A.D., the Celtic mill evolved into an intermediate type with two millstones superimposed and integrated, featuring
10286-403: The cool season from October to April, as a result of a phenomenon known as mountain waves . Mountain waves are strongest in a narrow area along the foothills and can create extensive areas of fallen trees and roof damage, especially around Cades Cove and Cove Mountain. Strong winds created by mountain waves were a contributing factor in the devastating Gatlinburg fire on November 28, 2016, during
10425-422: The countryside, owned by municipalities, cooperatives or private individuals. However, still in use today, nether millstones are still part of Mexico's rural heritage. The town of Olynthus was destroyed in 348 BC by Philip II of Macedonia , and the name " Olynthus millstone, Olynthus grinder, Olynthus mill " has come to be attached to this type of mill, which represents a genuine technical revolution . In 1917,
10564-491: The densest American black bear population east of the Mississippi River. Most of the range's adult black bears weigh between 100 pounds (45 kg) and 300 pounds (140 kg), although some weighing as much as 600 pounds (270 kg) have been documented in the park. An estimated 1,900 black bears reside in the park, although the exact figure is variable. The Smokies are home to 27 species of rodents, including
10703-478: The end of Antiquity, and then throughout the Middle Ages ; it only began to give way to the advances of water and then wind mills. With a diameter limited to the reach of an arm's movement, i.e. 40 to 70 cm, the hand mill could only produce a limited quantity of flour and was therefore essentially reserved for domestic use. By increasing the diameter and, above all, the height of the meta (nether millstone) and
10842-649: The end of the 19th century, when it was gradually replaced by a new type of metal tool . However, it can still be seen in rural domestic installations, such as in India , where 300 million women used hand mills daily to produce flour in 2002. The earliest evidence for stones used to grind food is found in northern Australia, at the Madjedbebe rock shelter in Arnhem Land , dating back around 60,000 years. Grinding stones or grindstones, as they were called, were used by
10981-472: The fibrous texture that would make them indigestible ( Scirpus maritimus ). The rhizomes of ferns and the peel of the fruit of the doum palm , also found on this site, benefit from being ground to improve their nutritional qualities; they thus complemented the meat diet of hunter-gatherers . Grinding barley or oat seeds was practiced at the end of the Upper Palaeolithic ( Franchthi ) or
11120-491: The force of animals or people. The metate is a nether millstone for domestic use, for grinding corn . It has been used for several thousand years (around 3000 BC) in the cultural area of Mesoamerica , and its name comes from the Nahuatl " metatl ". Today's millstones are monolithic, usually made of basalt , apodous, or tripod, rectangular, and slightly concave on the grinding surface. These millstones are associated with
11259-435: The forests in the park are estimated to be old-growth forest , with many trees that predate European settlement of the area. This is one of the largest blocks of deciduous , temperate , old growth forest in North America. Most of the forest is a mature second-growth hardwood forest. The variety of elevations, the abundant rainfall, and the presence of old growth forests give the park an unusual richness of biota . The park
11398-565: The handle of a millstone in Korea was made from an ash tree, the process for making a handle from the ash tree was known as "Mulpure-namu". To ensure that everything is "all right" with the creation of a millstone, a mason within ancient Kora offered food and alcohol in a ritual. Millstones were introduced to Britain by the Romans during the 1st century AD and were widely used there from the 3rd century AD onwards. In 1932-1933 in Ukraine, during
11537-470: The harsh mountain tops, typically above 5,500 feet (1,700 m). About 10,600 acres (43 km ) of the spruce-fir forest are old-growth. The spruce-fir forest consists primarily of two conifer species— red spruce ( Picea rubens ) and Fraser fir ( Abies fraseri ). The Fraser firs, which are native to southern Appalachia, once dominated elevations above 6,200 feet (1,900 m) in the Smokies. Most of these firs were killed, however, by an infestation of
11676-629: The higher elevations in the Smokies are cool enough to support forest types more commonly found in the northern United States. The northern hardwood forests constitute the highest broad-leaved forest in the eastern United States. About 28,600 acres (116 km ) are old-growth. In the Smokies, the northern hardwood canopies are dominated by yellow birch ( Betula alleghaniensis ) and American beech ( Fagus grandifolia ). White basswood ( Tilia heterophylla ), mountain maple ( Acer spicatum ) and striped maple ( Acer pensylvanicum ), and yellow buckeye ( Aesculus flava ) are also present. The understory
11815-400: The higher elevations. Flash flooding often occurs after heavy rain. The average temperature difference between the mountains, such as Newfound Gap at 5,048 ft (1,539 m) above MSL , and the valleys at about 1,600 ft (488 m), is between 10–13 °F (5.6–7.2 °C) for highs, and between 3–6 °F (1.7–3.3 °C) for lows. The difference between high temperatures
11954-639: The history of the park. They also sell books, maps, and souvenirs. Little River Gorge road, which runs along the Little River and connects to US 441 at the Sugarlands Visitor Center. There are 850 miles (1,370 km) of trails and unpaved roads in the park for hiking. A total of the 71.6 miles (115.2 km) of the Appalachian Trail (AT) are located within the park. The AT enters the park atop Fontana Dam, and ascends
12093-419: The installation of the double lever or the use of a crank fixed to the center of the millstone (14th - 15th centuries), meant that this type of hand mill was used in the countryside until the 20th century. Because they wear more quickly, this type of millstone requires a stricter selection of stones, among which basalt has a privileged place. Most of the stone used in Roman times seems to have come from just
12232-432: The iron furnace in 1885, but continued operating the mill. In December 1900, the Pigeon Forge Mill was purchased by local businessman A.T. Householder. Shortly afterward a generator was installed, providing electricity to the string of houses that occupied the river opposite the mill. The current milldam was completed in 1916. The mill was remodeled several times throughout the 20th century by subsequent owners to cater to
12371-511: The knees, spinal deformity and deformation of the first metatarsal , pathologies associated with long periods of bending while grinding, supporting the theory that early humans practiced a sexual division of labor . In India, millstone ( Chakki ) were used to grind grains and spices. These consist of a stationary stone cylinder upon which a smaller stone cylinder rotates. Smaller ones, for household use, were operated by two people. Larger ones, for community or commercial use, used livestock to rotate
12510-841: The majority of the Great Smoky Mountains , a subrange of the Blue Ridge Mountains , which are a subrange of the Appalachian Mountains . The range runs roughly east to west, nestled between the Bald Mountains to the east, the Plott Balsams to the south, and the Unicoi Mountains to the west. The park also protects a small portion of foothills , which separate the range from the Ridge-and-Valley Appalachians to
12649-499: The man-made famine known as Holodomor , the Soviet authorities prohibited the use of millstones, claiming that a millstone is a "mechanism for enrichment" (which was a negative term in Soviet communist ideology). This forced Ukrainian villagers to hide their manually-operated millstones and use them secretly during the famine. In response, Soviet authorities regularly searched villages for "illegal" millstones and destroyed them. In 2007,
12788-562: The military. In the early 1900s, a generator was installed at the mill which provided electricity to the area until 1930. After the establishment of the Great Smoky Mountains National Park a few miles to the south in 1934, Pigeon Forge gradually evolved into a tourist boom town, and the mill became a popular stop for passing tourists. The Pigeon Forge Mill is situated on the east bank of the West Fork of
12927-427: The mill site. The interior of the mill consists of hand-hewn hemlock and oak walls, held together by hickory pegs, and the millhouse's exterior walls have been weatherboarded with yellow poplar boards. The floor consists of nailed pine boards. The elongated section on the north side of the millhouse was built in the latter half of the 19th century to house the mill's new sawmill. The Pigeon Forge Mill makes use of both
13066-402: The mill's immediate vicinity. The Pigeon Forge Mill is located on land that was originally part of a 151-acre (61 ha) plot of land granted in 1810 to Mordecai Lewis (1751–1817), a Revolutionary War veteran from Virginia . Before his death, Lewis may have erected a tub mill along the river (no longer standing). In 1817, Lewis's son-in-law, Isaac Love, built the iron forge for which
13205-442: The milling of wild cereals in the early Upper Paleolithic, at least in Europe, there is no reason not to believe that other plant matter ( acorns , nuts , hazelnuts , etc.) and animal matter ( fat ) were already being ground into paste before cooking. Similarly, it's likely that millstones were being used at this time for technical purposes, to crush mineral substances ( dyes ) and certain plant or animal fibers for technical use. In
13344-412: The millstones became flatter, and a number of improvements were introduced, such as an upper wedge to center the movable wheel on the pivot. A device for adjusting the distance between the millstones (the anille ) also appeared, enabling grinding quality to be controlled (1st century B.C.), and radii cut into the millstone could accentuate the natural abrasiveness of the stone. Later developments, such as
13483-513: The most common hawk species, have been sighted at all elevations. Owl species include the barred owl , eastern screech owl , and northern saw-whet owl . The Great Smoky Mountains National Park is home to one of the world's most diverse salamander populations, and is known as the "Salamander Capital of the World". Five of the world's nine families of salamanders are found in the range, consisting of up to 31 species. The red-cheeked salamander
13622-474: The mountain on The Boulevard Trail . It can accommodate 12 people per night and is the only backcountry site in the park that has a permanent ban on campfires. Another popular hiking trail leads to the pinnacle of the Chimney Tops , so named because of its unique dual-humped peaktops. This short but strenuous trek rewards nature enthusiasts with a spectacular panorama of the surrounding mountain peaks. It
13761-722: The nature of the action exerted on the material and the gesture performed; the function of the tool can then be specified, as well as the activity in which it participated. Neanderthal people were already using rudimentary tools to crush various substances, as attested by the presence of rudimentary grinders at the end of the Mousterian and millstones in the Châtelperronian . From the Aurignacian period onwards (around 38,000 years ago), Cro-Magnon man regularly used millstones, elongated grinders, and circular wheels. From
13900-602: The north. From west to east, the range gradually widens, with most of the highest mountains located in the eastern half. Elevations in the park range from about 875 feet (267 m) to 6,643 feet (2,025 m) at the summit of Kuwohi . Kuwohi is the highest mountain in Tennessee and the third-highest mountain east of the Mississippi River . The park contains 16 of the " Southern Sixers "; mountains in Tennessee and North Carolina that reach elevations higher than 6,000 feet (1,800 m). The second highest mountain in
14039-436: The northeastern part of the park on narrow ridges at elevations between 3,600 and 5,200 feet (1,100 and 1,600 m). Grass balds are mountaintop meadows that are mostly covered in grasses and sedges . They are typically found on rounded mountaintops or slopes in the southwestern part of the park at elevations ranging from 4,500 to 5,700 feet (1,400 to 1,700 m). Mixed oak-pine forests are found on dry ridges, especially on
14178-504: The only trout species native to the range, although northwestern rainbow trout and European brown trout were introduced in the first half of the 20th century. The larger rainbow and brown trout outcompete the native brook trout for food and habitat at lower elevations. As such, most of the brook trout found in the park today are in streams above 3,000 feet in elevation where temperatures are typically below 61 °F (16 °C). Trout are generally smaller than in different locales, due to
14317-445: The ore into pig iron, and a 500-pound (230 kg) trip hammer that molded the pig iron into bar iron. In 1830, Love and his sons built a large gristmill adjacent to the iron furnace, which was used by local farmers to grind grain. As his iron business was never profitable, Love eventually ceased iron production, and sold the entire operation to Alexander Preston in 1841. On May 29 of that same year, Isaac's son, William, established
14456-527: The park as a stopover and for foraging for food. Species that thrive in southern hardwood forests, such as the red-eyed vireo , wood thrush , wild turkey , northern parula , ruby-throated hummingbird , and tufted titmouse , are found throughout the lower elevations and cove hardwood forests. Species more typical of cooler climates, such as the raven , winter wren , black-capped chickadee , yellow-bellied sapsucker , dark-eyed junco , and Blackburnian , chestnut-sided , and Canada warblers , are found in
14595-520: The park in phases between 1986 and 1994. Elk were reintroduced to the park in 2001 and 2002. Today they are most abundant in the Cataloochee area in the southeastern section of the park. European wild boar , introduced as game animals in the early 20th century, thrive in southern Appalachia but are considered a nuisance because of their tendency to root up and destroy plants. The boars are seen as taking food resources away from bears as well, and
14734-419: The park include the American toad and the American bullfrog , wood frog , upland chorus frog , northern green frog , and spring peeper . Reptiles found within the park include eight species of turtles , nine species of lizards , and 23 species of snakes . 21 of these snake species are from the family Colubridae , and include multiple kingsnakes , the black rat snake , the northern water snake , and
14873-400: The park include the eastern fence lizard , green anole , and multiple species of skinks . The rarest lizard in the park is the eastern slender glass lizard , a legless lizard often mistaken for a snake. Fish include trout , lamprey , darter , shiner , bass , minnows , and sucker . An estimated 1,073 miles (1,727 km) of streams in the park support fish. The brook trout is
15012-475: The park is Mount Guyot , at an elevation of 6,621 feet (2,018 m). Mount Le Conte , at an elevation of 6,593 feet (2,010 m), rises 5,301 feet (1,616 m) from its base to its summit, making it the tallest mountain in the United States east of the Rocky Mountains . Nestled between the mountains are a number of deep valleys, some of which are known as coves . The largest and most prominent
15151-428: The park service has sponsored a program that pays individuals to hunt and kill boars and leave their bodies in locations frequented by bears. The Smokies are home to a diverse bird population due to the presence of multiple forest types. Nearly 120 bird species are known to use the park as a breeding ground, including 52 from the neotropics and additional ones from northern climatic regions. Other migratory species use
15290-700: The park, separating the range from the Bald Mountains to the east. The Plott Balsams border the range to the south. Several smaller rivers have their source in the park, including the three prongs of the Little Pigeon River , the Oconaluftee River , and the Little River . Other major streams include Hazel Creek and Eagle Creek in the southwest, Raven Fork near Oconaluftee, Cosby Creek near Cosby , and Roaring Fork near Gatlinburg . More than 100 prominent waterfalls are located within
15429-418: The park. Plants and animals common in the country's Northeast have found suitable ecological niches in the park's higher elevations, while southern species find homes in the balmier lower reaches. The forests of the Smokies are typically divided into three zones—The cove hardwood forests in the stream valleys, coves, and lower mountain slopes; the northern hardwood forests on the higher mountain slopes; and
15568-544: The park. The tallest is Ramsey Cascades, located at the base of Mt. Guyot. This waterfall drops 100 feet (30 m) over rock outcroppings into a small pool below. Rainbow Falls is the tallest single-drop waterfall, plunging 80 feet (24 m) along LeConte Creek. Other popular waterfalls include Grotto Falls, Laurel Falls, Abrams Falls, Mingo Falls, Mouse Creek Falls, and Hen Wallow Falls. The park service maintains four historic districts and one archaeological district within park boundaries, as well as nine individual listings on
15707-581: The people of Victorivka village in Cherkasy Oblast built a monument using the millstones they had managed to hide and save from the Soviet plunder during the Holodomor . The preparation of vegetable products ( roots , tubers , almonds , leaves , etc.), animal products ( marrow , tendons , etc.), or mineral products ( ochre ) by grinding or milling, for consumption or technical use, has existed for several dozen millennia. Unlike crushing, in which
15846-591: The place where the millstone is located was a space reserved for women. A couple often acquires, or is given, a millstone when they set up home. This acquisition represents a major expense in the life of a Mixtec peasant, as evidenced by the wills of nobles and wealthy peasants from the 16th to 18th centuries, which included metates. Daily tortillas are made from sufficiently moistened corn dough , which, unlike flour, cannot be preserved. This technical characteristic no doubt explains why domestic metates were not replaced centuries ago by mills, as they were in Europe. During
15985-508: The pressure is exerted only moderately, without breaking the stones, which would give bad taste. The resultant pulp could then be subjected to the action of a press to collect the oil. A melting pot of African, Eastern and Mediterranean civilizations, Morocco has preserved tools and techniques from different eras. The Volubilis site, located in Mauritania Tingitana (northeastern Morocco), features grain and olive mills from
16124-415: The rainy and temperate climate. No other location of similar size within a temperate climate is known to match the park's biodiversity. Forests cover approximately 95 percent of the Great Smoky Mountains National Park. The lower region forests are dominated by deciduous leafy trees. At higher altitudes, deciduous forests give way to coniferous trees like Fraser fir . An estimated 20 to 25 percent of
16263-628: The range. Trees were unable to survive at the higher elevations and were replaced by tundra vegetation. Spruce-fir forests occupied the valleys and slopes below approximately 4,950 feet (1,510 m). The persistent freezing and thawing during this period created the large blockfields that are often found at the base of large mountain slopes. According to the Köppen climate classification system, Great Smoky Mountains National Park has two climate types: humid subtropical (Cfa), and temperate oceanic (Cfb). The plant hardiness zone at Kuwohi Visitor Center
16402-424: The red spruce fail to encroach into the beech gaps is unknown. The Southern Appalachian spruce–fir forest —also called the "boreal" or "Canadian" forest—is a relict of the ice ages , when mean annual temperatures in the Smokies were too cold to support a hardwood forest. While the rise in temperatures between 12,500 and 6,000 years ago allowed the hardwoods to return, the spruce-fir forest has managed to survive on
16541-886: The red spruces are believed to be 300 years old, and the tallest rise to over 100 feet (30 m). The main difference between the Southern Appalachian spruce–fir forest and the spruce-fir forests in northern latitudes is the dense broad-leaved understory of the former, which are home to catawba rhododendron , mountain ash , pin cherry , thornless blackberry, and hobblebush . The herbaceous and litter layers are poorly lit year-round and are thus dominated by shade-tolerant plants such as ferns, namely mountain wood fern and northern lady fern , and over 280 species of mosses. The Great Smoky Mountains National Park has over 1,400 flowering plant species . Many wildflowers grow in mountains and valleys, including bee balm , Solomon's seal , Dutchman's breeches , various trilliums ,
16680-410: The ridgeline of the Great Smoky Mountains , part of the Blue Ridge Mountains , which are a division of the larger Appalachian Mountain chain . The park contains some of the highest mountains in eastern North America, including Kuwohi , Mount Guyot , and Mount Le Conte . The border between the two states runs northeast to southwest through the center of the park. The Appalachian Trail passes through
16819-408: The rotating millstone spread at the end of the 5th century BC from Spain, and that it was directly derived from attempts to perfect the Olynthus mill. André Leroi-Gourhan states that " the transformation of rectilinear reciprocating motion into circular-continuous motion leads to another form of milling ". Some authors do not agree on its geographical origin, located for some " towards Carthage and
16958-563: The ruins of the town of Olynthus : it was the millstone of an oil mill , not a flour mill. Historians Marie-Claire Amouretti and Georges Comet point out that these millstones pre-date the earliest known examples of circular grain mills. So it was probably through oil production that the first rotary crushing machine was introduced. Cereals and other fruits and seeds followed. The oldest rotating millstone are thought to have originated in Spain 2,500 years ago(600 BC - 400 BC). It seems that
17097-418: The second-most visited tourist attraction in Tennessee, Ober Gatlinburg , and Ripley's Aquarium of the Smokies. Tourism to the park contributes an estimated $ 2.5 billion annually into the local economy. The Great Smoky Mountains National Park covers a total of 522,419 acres (816.280 sq mi; 211,415 ha; 2,114.15 km ) The park is roughly evenly divided between Tennessee and North Carolina, and
17236-456: The size of peas, throw it into the millstones, in numerous lines, two or three people standing at each lever and grind it." Photius' version specifies " on either side " of the lever. It's also known as a "hand millstone", "arm millstone" or "moulinet", and in Latin as a " molendinum bracchis " or " molendinum manuale ". According to de Barry, the oldest circular stone millstone was unearthed in
17375-453: The south-facing North Carolina side of the range. Cove hardwood forests, which are native to southern Appalachia, are among the most diverse forest types in North America. The cove hardwood forests of the Smokies are mostly second-growth, although some 72,000 acres (290 km ) are still old-growth. They are found in the valleys between mountain ridges at elevations below 4,500 feet (1,400 m) in deep moist soil. The Albright Grove along
17514-408: The spruce-fir and northern hardwood zones. Ovenbirds , whip-poor-wills , and downy woodpeckers live in the drier pine-oak forests and heath balds. Bald eagles and golden eagles have been spotted at all elevations in the park. Peregrine falcon sightings are also not uncommon, and a peregrine falcon eyrie is known to have existed near Alum Cave Bluffs throughout the 1930s. Red-tailed hawks ,
17653-407: The spruce-fir or boreal forest at the very highest elevations. Appalachian balds —patches of land where trees are unexpectedly absent or sparse—are interspersed through the mid-to-upper elevations in the range. Balds include grassy balds and heath balds. Heath balds are covered mostly in shrubbery that is part of the heath family such as rhododendron and mountain laurel. They are primarily found in
17792-407: The tourist traffic along US-441. The Pigeon Forge Mill is a three-story structure supported by 14-foot (4.3 m) by 14-foot (4.3 m) yellow poplar logs, which in turn rest on several pillars of large river rock (now reinforced by concrete). These pillars have helped preserve the mill through several disastrous floods, most notably floods in 1875 and 1920, both of which washed away bridges at
17931-465: The trails with the largest net elevation gain east of the Mississippi River. Hikers may spend a night at the LeConte Lodge, located near the summit, which provides cabins and rooms for rent except during the winter season. Accessible solely by trail, it is the only private lodging available inside the park, and the highest inn in the eastern United States. The Mt. LeConte Shelter is located atop
18070-412: The truncated surface of the lying millstone and on the inside of the grinding ring. Columella asserts that, to extract the oil, the millstones ( molae ) are more useful than the crusher ( trapetum ), as they can be lowered or raised according to the size of the fruit, so as to avoid crushing the stone. A second type of olive mill can be found on the same site, and consists of a monolithic vat on which
18209-421: The two, and all of the blooms progress from lower to higher elevations. The reverse is true in autumn, when nearly bare mountaintops covered in rime ice (frozen fog) can be separated from green valleys by very bright and varied leaf colors. The rhododendrons are broadleafs , whose leaves droop in order to shed wet and heavy snows that come through the region during winter. The Great Smoky Mountains National Park
18348-583: The upper cylinder. Today a majority of the stone flour mills (Atta Chakki) are equipped with lower stone rotating and upper stone stationary millstones also called Shikhar Emery Stones which are made from abrasive emery grains and grits, with a binding agent similar to Sorel Cement. These stones are made from two types of emery abrasives - Natural Jaspar Red Emery or Synthetic Calcined Bauxite Black Emery. In Korea, there were three different millstones, each made from different materials, serving other purposes, such as threshing, grinding, and producing starch. Generally,
18487-557: The wars of the 19th century and the Mexican Revolution of 1910 , Mexican armies were accompanied by women and metates to ensure the stewardship of the country; the Spanish conquest did not replace tortillas with bread - quite the contrary. At the end of the 19th century, the owners of the large plantations introduced motorized corn mills, which freed up female labor for the fields. From 1920 onwards, electric mills appeared in
18626-608: Was arguably the most beloved tree of the range's pre-park inhabitants, was killed off by the introduced Chestnut blight in the early-to-mid 20th century. The understories of the cove hardwood forest contain dozens of species of shrubs and vines. Dominant species in the Smokies include the Eastern redbud ( Cercis canadensis ), flowering dogwood ( Cornus florida ), Catawba rhododendron ( Rhododendron catawbiense ), mountain laurel ( Kalmia latifolia ), and smooth hydrangea ( Hydrangea arborescens ). The mean annual temperatures in
18765-559: Was considered the most polluted national park. From 1999 to 2003, the park recorded approximately 150 unhealthy air days, the equivalent of about one month of unhealthy air days per year. In 2013, Colorado State University reported that, with the passing of the United States Clean Air Act in 1970 and the subsequent implementation of the Acid Rain Program , there had been a "significant improvement" to
18904-603: Was invented by Aristaeus , and excavations at Olynthus have revealed examples dating back to the 5th century BC. The trapetum was precisely described by Cato the Elder, who gave us the technical names of all its parts. Excavations at Stabies, Pompeii , the villa at Boscoreale and in Roman Africa show that the system was widely used in ancient Rome and disappeared with it. The trapetum consists of two plano-convex millstones (3, orbes ), standing vertically, supported by
19043-441: Was not limited to grinding cereals, as the finds from Thasos or Lavrio suggest: it was also used to grind ore, so as to calibrate it for subsequent selection by washing. It may even have appeared in the mines of Pangaion Hills . The text by Agatharchides on the gold mines of Egypt in the 1st century B.C., transmitted by Photios and Diodorus , mentions a mill with a lever: "Women and older men then receive this ore crushed to
19182-481: Was the first national park having land and other costs paid in part with federal funds; previous parks were funded wholly with state money or private funds. The park was designated as a UNESCO World Heritage Site in 1983 and an International Biosphere Reserve in 1988. The park anchors a large tourism industry based in Sevier County, Tennessee , adjacent to the park. Major attractions include Dollywood ,
19321-567: Was the flashpoint for the 2016 Great Smoky Mountains wildfires , and therefore sustained extensive damage, evident still today in clearly visible burn scars. The extreme heat of the fires resulted in accelerated weathering and potential mass wasting of the exposed rock, and therefore access to the summit is no longer permitted for safety reasons. Both the Laurel Falls and Kuwohi trails offer relatively easy, short, paved paths to their respective destinations. The Laurel Falls Trail leads to
