74-597: Lake Chippewa was a prehistoric proglacial lake. The basin is now Lake Michigan . It formed about 10,600 years before present (YBP). The lake occupied the depression left by the Michigan Lobe of the Laurentide Ice Sheet . The lake formed from glacial Lake Algonquin as water levels dropped, occupying only the deepest parts of the Lake Michigan basin. The waters drained through
148-637: A British colonial and early American military base and fur trade center, founded in 1781. With the advent of European exploration into the area in the late 17th century, Lake Michigan became used as part of a line of waterways leading from the Saint Lawrence River to the Mississippi River and thence to the Gulf of Mexico . French coureurs des bois and voyageurs established small ports and trading communities, such as Green Bay, on

The lake is a great place to view ice volcanoes, which typically occur at the start of the winter season. Woodland period In the classification of archaeological cultures of North America , the Woodland period of North American pre-Columbian cultures spanned a period from roughly 1000 BCE to European contact in
296-412: A massive demographic-shift, as their western neighbors fled the violence. The Iroquois sought refuge to the west and north of Lake Michigan. The Straits of Mackinac were an important Native American travel corridor and fur-trade route. Located on the southern side of the straits sits the town of Mackinaw City, Michigan , the site of Fort Michilimackinac (a reconstructed French fort founded in 1715); on
370-466: A point between Milwaukee and Racine to a point between Grand Haven and Muskegon, divides the lake into northern and southern basins. Each basin has a clockwise flow of water, deriving from rivers and winds. Prevailing westerly winds tend to move the surface water toward the east, producing a moderating effect on the climate of western Michigan. There is a mean difference in summer water temperatures of 5 to 10 degrees Fahrenheit (2 to 5 degrees Celsius) between
444-498: A result of improvements to the Welland Canal in 1918, an invasion of sea lampreys and overharvesting , there has been a decline in native lake trout populations, ultimately causing an increase in the population of another invasive species, the alewife . As a result, salmonids, including various strains of brown trout , steelhead ( rainbow trout ), coho and chinook salmon , were introduced as predators in order to decrease
518-571: A round body, and lines of decoration with cross-etching on rim. The Havana style found in Illinois had a decorated neck. One of the major tools unique to this era was Snyders Points. These were quite large and corner-notched. They were made by soft-hammering percussion, and finished by pressure flaking. Although many of the Middle Woodland cultures are called "Hopewellian", and groups shared ceremonial practices, archeologists have identified
592-530: A row in 2020. Lake levels tend to be the lowest in winter. The normal low-water mark is 1.00 foot (30 cm) below datum ( 577.5 ft or 176.0 m ). In the winter of 1964, Lakes Michigan and Huron reached their lowest level at 1.38 feet (42 cm) below datum. As with the high-water records, monthly low-water records were set each month from February 1964 through January 1965. During this twelve-month period, water levels ranged from 1.38 to 0.71 feet (42–22 cm) below Chart Datum. The all-time low-water mark

Many Woodland peoples used spears and atlatls until the end of the period, when they were replaced by bows and arrows ; however, Southeastern Woodland peoples also used blowguns . The most cited technological distinction of this period
740-526: A variety of mortuary gifts, many of which were not local. Among the traded materials were copper from the Lake Superior deposits; silver from Lake Superior and especially Ontario; galena from Missouri and Illinois; mica from the southern Appalachians; chert from various places including Ohio, Indiana, and Illinois; pipestone from Ohio and Illinois; alligator teeth from the lower Mississippi Valley eastward to Florida; marine shells, especially whelks, from
814-435: A variety of other small and large mammals were hunted also, including beaver , raccoon , and bear . Shellfish formed an important part of the diet, attested to by numerous shell middens along the coast and interior rivers. Coastal peoples practiced seasonal mobility, moving to the coast during the summer to take advantage of numerous marine resources such as sea mammals and shellfish, then moved to interior locations during

Green Bay in the northwest is its largest bay. Grand Traverse Bay in its northeast is another large bay. Lake Michigan's deepest region, which lies in its northern half, is called Chippewa Basin (named after prehistoric Lake Chippewa ) and
962-649: Is believed to have been core to the Meadowood Interaction Sphere, in which cultures in the Great Lakes region, the St. Lawrence region, the Far Northeast, and the Atlantic region interacted. The large area of interaction is indicated by the presence of Adena-style mounds, the presence of exotic goods from other parts of the interaction spheres, and the participation in the "Early Woodland Burial Complex" defined by William Ritchie Pottery
1036-647: Is believed to have been the first European to reach Lake Michigan, possibly in 1634 or 1638. In the earliest European maps of the region, the name of Lake Illinois has been found (named for the Illinois Confederation of tribes), in addition to that of "Michigan". During the 1640s and 1650s, the Beaver Wars (over the fur trade with the European colonies), initiated by the Iroquois , forced

Lake Michigan is the only Great Lake that is wholly within the borders of the United States; the others are shared with Canada. Lake Michigan has a surface area of 22,404 sq mi (58,030 km ); (13,237 square miles (34,280 km ) lying in Michigan, 7,358 square miles (19,060 km ) in Wisconsin, 234 square miles (610 km ) in Indiana, & 1,576 square miles (4,080 km ) in Illinois) making it
1184-459: Is especially true for the middle woodland period and perhaps beyond. C. Margaret Scarry states "in the Woodland periods, people diversified their use of plant foods ... [they] increased their consumption of starchy foods. They did so, however, by cultivating starchy seeds rather than by gathering more acorns." Smith and Yarnell refer to an "indigenous crop complex" as early as 3800 B.P. in parts of

This period is variously considered a developmental stage, a time period, a suite of technological adaptations or "traits", and a "family tree" of cultures related to earlier Archaic cultures. It can be characterized as a chronological and cultural manifestation without any massive changes in
1332-564: Is separated from South Chippewa Basin by a relatively shallower area called the Mid Lake Plateau. In the mid 20th century, construction of the Saint Lawrence Seaway and Great Lakes Waterway opened the Great Lakes to ocean-going vessels. But the wider ocean-going container ships that were developed later do not fit through the locks on these routes, which limits shipping on the lakes. Lake freighters are used on
1406-485: Is supported by tourism , with large seasonal populations attracted by Lake Michigan. Many seasonal residents have summer homes along the waterfront and return to other homes for the winter. The southern tip of the lake near Gary, Indiana, is heavily industrialized. Cities on the shores of Lake Michigan include: Illinois Indiana Michigan Wisconsin The National Park Service maintains

The Conference came into force, in December 2008, with the enactment of laws in all of
1702-731: The Orange culture and in Georgia with the Stallings culture . Nevertheless, these early sites were typical Archaic settlements, differing only in the use of basic ceramic technology. As such, researchers are now redefining the period to begin with not only pottery, but the appearance of permanent settlements, elaborate burial practices, intensive collection and/or horticulture of starchy seed plants (see Eastern Agricultural Complex ), differentiation in social organization, and specialized activities, among other factors. Most of these are evident in

The Manistee National Forest section of the shoreline includes the Nordhouse Dunes Wilderness . The Lake Michigan division of the Michigan Islands National Wildlife Refuge is also within the lake, as are the Green Bay National Wildlife Refuge and
1850-782: The Southeastern Woodlands by 1000 BCE. In some areas, like South Carolina and coastal Georgia, Deptford culture pottery manufacture ceased after c. 700 CE . In coastal regions, many settlements were near the coast, often near salt marshes, which were habitats rich in food resources. People tended to settle along rivers and lakes in both coastal and interior regions for maximum access to food resources. Nuts were processed in large amounts, including hickory and acorns , and many wild berries, including palm berries, blueberries , raspberries , and strawberries , were eaten, as well as wild grapes and persimmon . Most groups relied heavily on white-tailed deer , but

There are numerous state and local parks located on the shores of the lake or on islands within the lake: Lake Michigan is home to a small variety of fish species and other organisms. It was originally home to lake whitefish , lake trout , yellow perch , panfish , largemouth bass , smallmouth bass and bowfin , as well as some species of catfish . As
2072-547: The 1000 CE ending of the Late Woodland period is traditional, in practice many regions of the Eastern Woodlands adopted the full Mississippian culture much later than that. Some groups in the north and northeast of the current United States , such as the Iroquois , retained a way of life that was technologically identical to the Late Woodland until the arrival of Europeans. Despite the widespread adoption of
2146-739: The Great Lakes Indian Fish and Wildlife Commission, which harvest 50 percent of the Great Lakes commercial catch in Michigan waters, and 45 state-licensed commercial fishing enterprises. The prime commercial species is the lake whitefish. The annual harvest declined from an average of 11 million pounds (5,000,000 kg) from 1981 through to 1999 to more recent annual harvests of 8 to 9.5 million pounds (3,600,000 to 4,300,000 kg). The price for lake whitefish dropped from $ 1.04/lb. to as low as $ 0.40/lb during periods of high production. Sports fishing includes salmon, whitefish, smelt , lake trout and walleye as major catches. In
2220-736: The Great Lakes by way of the Erie Canal and Hudson River in New York. The Erie Canal connects to the Great Lakes at the east end of Lake Erie (at Buffalo, New York ) and at the south side of Lake Ontario (at Oswego, New York ). The lake fluctuates from month to month with the highest lake levels typically occurring in summer. The normal high-water mark is 2.00 feet (0.61 m) above datum ( 577.5 ft (176.0 m) ). In October 1986, Lakes Michigan and Huron reached their highest level at 5.92 feet (1.80 m) above datum. The monthly average high-water records were broken for several months in
2294-505: The Michigan state stone, can be found. The beaches of the western coast and the northernmost part of the east coast are often rocky, with some sandy beaches. The southern and eastern beaches are typically sandy and dune-covered. This is partly because of the prevailing winds from the west (which also cause thick layers of ice to build on the eastern shore in winter). The Chicago city waterfront has been developed for parks, beaches , harbors and marinas, and residential developments connected by

2368-516: The Mississippian period from c. 1000 –1400 CE and may have continued up to European contact, around 500 years ago. The Early Woodland period continued many trends begun during the Late and Terminal Archaic periods, including extensive mound-building, regional distinctive burial complexes, the trade of exotic goods across a large area of North America as part of interaction spheres,
2442-501: The Northwest/Plains regions widely adopted pottery somewhat later, about 200 BCE. The Adena culture built conical mounds in which single- or multiple-event burials, often cremated, were interred along with rich grave goods including copper bracelets, beads, and gorgets , art objects made from mica, novaculite, hematite, banded slate, and other kinds of stone, shell beads and cups, and leaf-shaped "cache blades". This culture

Counted together, it is the largest body of fresh water in the world by surface area. The Mackinac Bridge is generally considered the dividing line between them. The main inflow to Lake Michigan from Lake Superior, through Lake Huron,

At that time, the Nipissing Great Lakes merged with the waters in the Michigan Basin and created a single lake encompassing all three of the upper Great Lakes . Somewhat smaller than Lake Michigan, Lake Chippewa extended through most of the Michigan Basin, north to the Straits of Mackinac, where there was a narrow channel which conveyed the lake's outflow over
2738-632: The communities and some clans resorted to raiding others for resources. Alternatively, the efficiency of bows and arrows in hunting may have decimated the large game animals, forcing the tribes to break apart into smaller clans to better use local resources, thus limiting the trade potential of each group. A third possibility is a colder climate may have affected food yields, possibly affected by Northern Hemisphere extreme weather events of 535–536 , also limiting trade possibilities. Lastly, it may be that agricultural technology became sophisticated enough that crop variation between clans lessened, thereby decreasing
2812-613: The cultivation of domesticated crops. In fact, it appears that hunting and gathering continued as the basic subsistence economy and that subsistence horticulture/agriculture did not occur in much of the Southeast for a couple of thousand years after the introduction of pottery, and in parts of the Northeast, horticulture was never practiced. This research indicated that a fiber-tempered horizon of ceramics greatly predates 1000 BCE, first appearing about 2500 BCE in parts of Florida with
2886-611: The deep bottom of Lake Michigan was J. Val Klump , a scientist at the University of Wisconsin–Milwaukee in 1985. Klump reached the bottom via submersible as part of a research expedition. The warming of Lake Michigan was the subject of a 2018 report by Purdue University . In each decade since 1980, steady increases in obscure surface temperature have occurred. This is likely to lead to decreasing native habitat and to adversely affect native species survival, including game fish. The Milwaukee Reef , running under Lake Michigan from

3108-429: The entire region (referred to as the "Hopewellian Interaction Sphere"). Such similarities could also be the result of reciprocal trade, obligations, or both between local clans that controlled specific territories. Access to food or resources outside a clan's territory would be made possible through formal agreements with neighbors. Clan heads would be buried along with goods received from their trading partners to symbolize
3182-412: The following Mississippian period, the beginning of serious cultivation greatly supplemented the traditional gathering of plants. Late Woodland settlements became more numerous, but the size of each one (with exceptions) was smaller than their Middle Woodland counterparts. The reasons for this are unknown, but it has been theorized that populations increased so much that trade alone could no longer support
3256-605: The following few hundred years, the region was the home of peoples known as the Late Woodland Native Americans . In the early 17th century, when Western European explorers made their first forays into the region, they encountered descendants of the Late Woodland Native Americans, mainly the historic Chippewa , Menominee , Sauk , Fox , Winnebago , Miami , Ottawa and Potawatomi peoples. The French explorer Jean Nicolet

For example, 90% of the grain shipped from Chicago traveled by ships east over Lake Michigan during the antebellum years. The volume rarely fell below 50% after the Civil War even with the major expansion of railroad shipping . The first person to reach

Some icebreakers ply the lakes. Lake Michigan is connected by the Illinois Waterway to the Gulf of Mexico via the Illinois River and the Mississippi River. Commercial tug-and-barge traffic on these waterways is heavy. Pleasure boats can enter or exit
3478-472: The largest lake entirely within one country by surface area ( Lake Baikal in Russia is larger by water volume) and the fifth-largest lake in the world. It is the larger half of Lake Michigan–Huron , which is the largest body of fresh water in the world by surface area. It is 307 miles (494 km) long by 118 miles (190 km) wide with a shoreline 1,640 miles (2,640 km) long. The lake's average depth

Like all of the Great Lakes, Lake Michigan is today used as a major mode of transport for bulk goods. In 2002, 162 million net tons of dry bulk cargo were moved via the Lakes. This was, in order of volume: iron ore, grain and potash . The iron ore and much of
3626-446: The lower water levels in 2013 were a combination of the "lack of a large snowpack" in the winter of 2011/2012 coupled with very hot and dry conditions in the summer of 2012. Since then water levels rebounded, rising more than 6 feet (1.8 meters) to historical record high levels. Lake Michigan, like the other Great Lakes, supplies drinking water to millions of people in bordering areas. The Great Lakes are collectively administered by

4070-638: The region. The beginning of the Middle Woodland saw a shift of settlement to the Interior. As the Woodland period progressed, local and inter-regional trade of exotic materials greatly increased to the point where a trade network covered most of the Eastern Woodlands . Throughout the Southeast and north of the Ohio River , burial mounds of important people were very elaborate and contained
4144-556: The relationships they had established. Under this scenario, permanent settlements would be likely to develop, leading to increased agricultural production and a population increase. Ceramics during this time were thinner and better quality than earlier times. Examples show pottery also was more decorated than Early Woodland. One style was the Trempealeau phase, which could have been seen by the Hopewell in Indiana. This type included
4218-594: The reliance on both wild and domesticated plant foods, and a mobile subsistence strategy in which small groups took advantage of seasonally available resources such as nuts, fish, shellfish, and wild plants. Pottery, which had been manufactured during the Archaic period in limited amounts, was now widespread across the Eastern Interior, the Southeast, and the Northeast. The Far Northeast, the Sub-Arctic, and

Large dune formations can be seen in many state parks, national forests and national parks along the Indiana and Michigan shoreline. Some of the most expansive and unique dune formations can be found at Indiana Dunes National Park , Saugatuck Dunes State Park , Warren Dunes State Park , Hoffmaster State Park , Silver Lake State Park , Ludington State Park , and Sleeping Bear Dunes National Lakeshore . Small dune formations can be found on

5032-625: The wildlife population. This program was so successful that the introduced population of trout and salmon exploded, resulting in the creation of a large sport fishery for these introduced species. Lake Michigan is now stocked annually with steelhead, brown trout, and coho and chinook salmon, which have also begun natural reproduction in some Lake Michigan tributaries. However, several introduced invasive species, such as lampreys, round goby , zebra mussels and quagga mussels , continue to cause major changes in water clarity and fertility, resulting in knock-on changes to Lake Michigan's ecosystem, threatening

In most areas construction of burial mounds decreased markedly, as did long-distance trade in exotic materials. At the same time, bow and arrow technology gradually overtook the use of the spear and atlatl . Agricultural production of the " Three Sisters " ( maize , beans , and squash ) was introduced. While full-scale intensive agriculture did not begin until

The region is often referred to as the " Third Coast " of the United States, after those of the Atlantic Ocean and the Pacific Ocean . The sand is often soft and off-white, known as " singing sands " because of the squeaking noise (caused by high quartz content) it emits when walked upon. Some beaches have sand dunes covered in green beach grass and sand cherries , and
5402-618: Was the widespread use of pottery (although pottery manufacture had arisen during the Archaic period in some places), and the diversification of pottery forms, decorations, and manufacturing practices. The increasing use of horticulture and the development of the Eastern Agricultural Complex , consisting of weedy seed plants as well as gourd cultivation, also meant that groups became less mobile over time and, in some times and places, people lived in permanently occupied villages and cities. Intensive agriculture characterizes
