102-748: The Platte is one of the most significant tributary systems in the watershed of the Missouri, draining a large portion of the central Great Plains in Nebraska and the eastern Rocky Mountains in Colorado and Wyoming . The river valley played an important role in the westward expansion of the United States, providing the route for several major emigrant trails, including the Oregon , California , Mormon and Bozeman trails. The first Europeans to see

204-484: A sink , which may be a permanent lake, a dry lake , or a point where surface water is lost underground . Drainage basins are similar but not identical to hydrologic units , which are drainage areas delineated so as to nest into a multi-level hierarchical drainage system . Hydrologic units are defined to allow multiple inlets, outlets, or sinks. In a strict sense, all drainage basins are hydrologic units but not all hydrologic units are drainage basins. About 48.71% of

306-414: A watershed , though in other English-speaking places, "watershed" is used only in its original sense, that of the drainage divide line. A drainage basin's boundaries are determined by watershed delineation , a common task in environmental engineering and science. In a closed drainage basin, or endorheic basin , rather than flowing to the ocean, water converges toward the interior of the basin, known as

408-771: A Spanish scout and explorer in the Southwest , was a war captain of the Spanish Indian auxiliaries. By 1714 (the same year the French explorers reached the Platte), he and a small exploration group from the south had reportedly already reached the Platte three times. He later guided the 1720 Villasur expedition to the area in a Spanish effort to stop French expansion onto the Great Plains. Naranjo and Villasur's party made

510-525: A U.S. Army officer on leave, led an expedition to the west financed by John Jacob Astor . They took wagons along the Platte, North Platte and Sweetwater River trail to the Green River in present-day Wyoming. The notable author Washington Irving wrote an account of Bonneville's explorations in the west that made him well known in the US. Following the fur traders, the major emigration trails established along

612-503: A canoe to travel far. The Platte River valley provided an easily passable wagon corridor; it sloped gradually up in height as it went almost due west from the Missouri. The Platte route had access to water, grass, buffalo and buffalo 'chips,' which the Indians and emigrants used as fuel for fires. Long Native American use had created trails on both sides of the muddy, about 1 mile (1.6 km) wide and shallow Platte River. The Platte's water

714-476: A dome-like mountain, covered with less resistant rock. Years of erosion and weathering removed the soil and rock leaving the exposed mountain. Soils on Pikes Peak above the timberline (approximately 12,000 ft or 3,700 m) are classified as Cirque land . Forests at lower altitudes mostly lie over the brown stony, sandy, loams of the Catamount loam or Ivywild loam series. The Devils Playground

816-454: A drainage basin, and there are different ways to interpret that data. In the unlikely event that the gauges are many and evenly distributed over an area of uniform precipitation, using the arithmetic mean method will give good results. In the Thiessen polygon method, the drainage basin is divided into polygons with the rain gauge in the middle of each polygon assumed to be representative for

918-540: A drainage boundary is referred to as watershed delineation . Finding the area and extent of a drainage basin is an important step in many areas of science and engineering. Most of the water that discharges from the basin outlet originated as precipitation falling on the basin. A portion of the water that enters the groundwater system beneath the drainage basin may flow towards the outlet of another drainage basin because groundwater flow directions do not always match those of their overlying drainage network. Measurement of

1020-470: A few miles up Ute Pass at Cascade . The road has a series of switchbacks, treacherous at high speed, called "The W's" for their shape on the northwest side of the mountain. The road is maintained by the city of Colorado Springs as a toll road . A project to pave the remainder of the road was completed on October 1, 2011. The project was in response to a suit by the Sierra Club over damage caused by

1122-624: A major emigration path to Denver. The wagon trails followed the south side of the Platte/North Platte River. Wagon trains were ferried or waded in low water years across the swampy-bottomed South Platte River in several places to stay on the south side of the North Platte River where the trails were located. Miners who later went on to Denver followed the South Platte River trail into Colorado. After

1224-938: A number of Nebraska stakeholders embarked upon the Platte River Cooperative Hydrology Study (COHYST). Conducted with assistance from the United States Geological Survey and the Natural Resources Conservation Service , this study attempts to arrive at a better understanding of the geology and hydrology of the Platte River basin from the Colorado and Wyoming borders to Columbus, including the Loup basin. This improved understanding could be used to develop policies for management of

1326-410: A perimeter, the drainage divide , made up of a succession of elevated features, such as ridges and hills . A basin may consist of smaller basins that merge at river confluences , forming a hierarchical pattern . Other terms for a drainage basin are catchment area , catchment basin , drainage area , river basin , water basin , and impluvium . In North America, they are commonly called

1428-404: A previously adopted closure of part of such river basin, subbasin, or reach to the issuance of additional water well permits, or to temporarily suspend or continue in effect a temporary suspension previously adopted on the drilling of new water wells in all or part of such river basin, subbasin, or reach. Most of the Platte River basin is currently considered as overappropriated. Beginning in 2004,

1530-406: A river basin, subbasin, or reach shall be deemed overappropriated if it is subject to an interstate cooperative agreement among more states and if, prior to such date, the state has declared a moratorium on the issuance of new surface water appropriations in such river, subbasin, or reach, and has requested each natural resources district jurisdiction in the affected area to close or continue in effect

1632-853: A small part of the southwest corner of Nebraska. The South Platte drains a large part of the Front Range mountains east of the continental divide. The part of the river labeled the South Platte is formed in Park County, Colorado , located southwest of Denver , in the South Park grassland basin and mountains east of the continental divide. It is formed by the confluence of the South Fork South Platte River and Middle Fork South Platte River , approximately 15 miles (24 km) southeast of Fairplay, Colorado . After

1734-592: Is a minor subpeak of Pikes Peak located on the northwest side of the mountain near the Pikes Peak Highway . The Devils Playground is named for the way lightning sometimes dances around the prominence during lightning storms. The Devils Playground is the highest point in Teller County at an approximate elevation of 13,075 feet (3,985 m). The first Europeans to see Pikes Peak were the Spanish in

1836-575: Is due to a large amount of potassium feldspar . It is thought that the granite was once magma that crystallized at least 20 miles (32 km) beneath the Earth's surface, formed by an igneous intrusion during the Precambrian , approximately 1.05 billion years ago, during the Grenville orogeny . Through the process of uplifting , the hardened rock pushed through the Earth's crust and created

1938-535: Is estimated at 3,240 cu ft/s (92 m/s). The Platte drains one of the most arid areas of the Great Plains with a flow that is considerably lower than rivers of comparable length in North America. For much of its length, it is a classic wide, muddy and shallow braided stream which in the lower reaches flows in a floodplain bordered by bluffs. During pioneer days, the common humorous description

2040-424: Is joined from the north by the about 70-mile-long (110 km) Loup River about 2 miles (3 km) southeast of Columbus. During pioneer days, a Loup River ferry crossed the river. From Columbus, the Platte flows almost due east about 50 miles (80 km) past North Bend and then on to Fremont . Near Fremont, the Platte bends south and then east around the location of Omaha in a large "L" turn. Near Fremont

2142-623: Is located in Pike National Forest , 12 miles (19 km) west of downtown Colorado Springs, Colorado . The town of Manitou Springs lies at its base. The mountain is named in honor of American explorer Zebulon Pike , even though he was unable to reach the summit. The summit is higher than any point in the United States east of its longitude . The band of Ute people who called the Pikes Peak region their home were

2244-425: Is much smaller due to the extensive water taken from it for irrigation. Historically, the North Platte River was up to a mile wide (1.6 km) in many places, as evidenced by the old streambed and historic written records. The South Platte River drainage includes about 28,000 square miles (73,000 km) in the north east corner of Colorado, parts of southeastern Wyoming in the vicinity of the city of Cheyenne and

2346-487: Is referred to as " watershed management ". In Brazil , the National Policy of Water Resources, regulated by Act n° 9.433 of 1997, establishes the drainage basin as the territorial division of Brazilian water management. When a river basin crosses at least one political border, either a border within a nation or an international boundary, it is identified as a transboundary river . Management of such basins becomes

2448-501: Is required by humans and animals not acclimated to high altitudes. Altitude sickness may develop in those who are sensitive or who over-exert themselves. The summit of Pikes Peak has a polar climate ( ET ) due to its elevation. Snow is a possibility any time year-round, and thunderstorms with high winds gusting up to 100 miles per hour (160 km/h) or more are common in the afternoons. Surrounding areas have different climatic variations depending on location and elevation. Much of

2550-614: Is the Dead Sea . Drainage basins have been historically important for determining territorial boundaries, particularly in regions where trade by water has been important. For example, the English crown gave the Hudson's Bay Company a monopoly on the fur trade in the entire Hudson Bay basin, an area called Rupert's Land . Bioregional political organization today includes agreements of states (e.g., international treaties and, within

2652-713: The African Great Lakes , the interiors of Australia and the Arabian Peninsula , and parts in Mexico and the Andes . Some of these, such as the Great Basin, are not single drainage basins but collections of separate, adjacent closed basins. In endorheic bodies of water where evaporation is the primary means of water loss, the water is typically more saline than the oceans. An extreme example of this

2754-475: The Central Flyway . Fossil evidence in the Platte River valley indicates this crane stopover has been active for over 10 million years. Since the mid-20th century, this river has shrunk significantly. This reduction in size is attributed in part to its waters being used for irrigation, and to a much greater extent to the waters diverted and used by the growing population of Colorado, which has outstripped

2856-765: The Continental Divide , northern Alaska and parts of North Dakota , South Dakota , Minnesota , and Montana in the United States, the north shore of the Scandinavian peninsula in Europe, central and northern Russia, and parts of Kazakhstan and Mongolia in Asia , which totals to about 17% of the world's land. Just over 13% of the land in the world drains to the Pacific Ocean . Its basin includes much of China, eastern and southeastern Russia, Japan,

2958-714: The Korean Peninsula , most of Indochina, Indonesia and Malaysia, the Philippines, all of the Pacific Islands , the northeast coast of Australia , and Canada and the United States west of the Continental Divide (including most of Alaska), as well as western Central America and South America west of the Andes. The Indian Ocean 's drainage basin also comprises about 13% of Earth's land. It drains

3060-612: The Mormon Trail north of the Platte River and had to ferry across the Elkhorn. After the Union Pacific railroad was constructed west from Omaha in 1866, it had to build a major bridge across the Elkhorn. After the confluence of the Elkhorn and the Platte River, the Platte continues southward, about 7 miles (11 km) before it turns sharply and heads almost due East for about 20 miles (32 km) before its confluence with

3162-592: The Nebraskier , after its Oto name, meaning "flat water". The French later applied the French word plate (meaning flat, and pronounced plat , or platte ) to the river. Occupied by various Indian tribes for part of each year, the Platte River territory had been claimed by both Spanish and French explorers trying to rule the Great Plains. Spain had claimed all of the Great Plains after Coronado's 1541–42 expedition. Jose Naranjo, an African - Hopi who served as

3264-622: The Oregon boundary dispute with Britain in 1846, the conclusion of the Mexican–American War in 1848, and the California Gold Rush in 1849 and other gold and silver strikes rapidly attracted increased emigrant traffic west. The Platte River in the future state of Nebraska and the North Platte River in Wyoming typically had many channels and islands. The waterways were often too shallow, crooked, muddy and unpredictable for

3366-697: The Routt National Forest and North Park near what is now Walden to Casper, Wyoming . Shortly after passing Casper, the North Platte turns to the east-southeast and flows about 350 miles (560 km) to the city of North Platte, Nebraska. In Colorado and Wyoming, the North Platte is narrower and much swifter flowing than it is in Nebraska, where it becomes a slow flowing, shallow braided stream . The North Platte River has been dammed about eight times for water storage and irrigation purposes in Wyoming and Nebraska as it flows to its confluence with

3468-570: The Tabeguache , whose name means the "People of Sun Mountain". Tava or "sun", is the Ute word that was given by these first people to the mountain that we now call Pikes Peak. (In contrast, the name Tabeguache Peak is now used for a peak further west.) It is thought that the Ute people first arrived in Colorado about 500 A.D., however their oral history states that they were created on Tava. In

3570-527: The groundwater . A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. Pikes Peak Pikes Peak is the highest summit of the southern Front Range of the Rocky Mountains in North America . The ultra-prominent 14,107-foot (4,299.83 m) fourteener

3672-585: The interior least tern are birds using the flyway which have been classified as endangered and are protected under the Platte River Endangered Species Partnership. Common plants in the Platte River area are big and little bluestem, switch grass, and cottonwood trees. White-tail deer, many types of catfish, Canada geese, and bald eagles attract fans. The Platte River area has long supported many animals but recently, due to urbanization and farming causing loss of habitat,

3774-479: The 1540s, dramatically changed life in the Great Plains. Indian tribes could more easily follow the buffalo herds as they migrated from north to south and back. Before 1870, herds of several hundred thousand bison (buffalo) periodically migrated across the Platte in following seasonal grazing. The animals often waded or swam across the Platte. The first-known European to see the Platte was the French explorer Étienne de Veniard, sieur de Bourgmont in 1714, who named it

3876-643: The 1700s. The first American sighting is often credited to members of the Pike Expedition , led by Zebulon Pike . After a failed attempt to climb to the top in November 1806, Pike wrote in his journal: The first European ascent of the peak came 14 years after Pike's discovery, in the summer of 1820. Edwin James , a young student who had just graduated from Middlebury College in Vermont , signed on as

3978-815: The 1800s, when the Arapaho people arrived in Colorado, they knew the mountain as Heey-otoyoo' meaning "Long Mountain". By comparison, the Pawnee called the same mountain Tûs Pêh ("Where the Heavens Touch the Earth"), and the Ute Indians called it Tava-Kaavi ("Sun Mountain"). Throughout its history, European peoples have called the mountain El Capitán, Grand Peak, Great Peak, James Peak, Long Mountain, and Pike's Peak. Early Spanish explorers named

4080-626: The Mississippi River to the British. The Spanish took over lands west of the Mississippi River. Since there were few fur-bearing animals on the Platte of interest to the fur traders , the French and British explorers and fur trappers ignored the Platte territory for some time. During the course of the Napoleonic Wars (1803–1815), France briefly reacquired the land west of the Mississippi River from Spain. In 1804, Napoleon sold

4182-540: The Missouri River. Sarpy County is shaped like a crescent, being bounded on the east by the Missouri River, on the south and west by the Platte, and on the north by Douglas County which contains Omaha. The Platte-Missouri River confluence is about 10 miles (16 km) south of Omaha. Including the North Platte River, the Platte River stretches over 850 miles (1,400 km), with a drainage basin of about 90,000 square miles (230,000 km). The mean annual flow

4284-469: The North Platte and the South Platte rivers join to form the Platte River, over most of its length it is a sandy, broad, shallow, braided river. Its many shallow channels and islands and ever-changing sandbars made navigation difficult; it was never used as a major water transportation route. The Platte flows in a large arc, east-southeast to near Fort Kearny and then east-northeast, across Nebraska south of Grand Island and on to Columbus . The Platte River

4386-557: The Pikes Peak area until the Cripple Creek Mining District was discovered southwest of Pikes Peak and led, in 1893, to one of the last major gold rushes in the lower 48 states. In July 1860, Clark, Gruber and Company commenced minting gold coins in Denver bearing the phrase "Pike's Peak Gold" and an artist's rendering of the peak (sight unseen) on the obverse . In 1863, the U.S. Treasury purchased

4488-550: The Platte is joined from the north by the Elkhorn River . The Elkhorn, a 290-mile-long (470 km) river, originates in the eastern Sandhills of Nebraska and is one of the largest tributaries of the Platte River. The Elkhorn joins the Platte on its south-bound path just southwest of Omaha, approximately 1 mile (2 km) south and 3 miles (5 km) west of Gretna . The pioneers leaving from near Omaha (established 1854) or Council Bluffs, Iowa (established 1846) used

4590-467: The Platte turns sharply and flows south-southeast about 10 miles (16 km) to about Waterloo, Nebraska —located about 20 miles (32 km) west of Omaha. Near Waterloo the Platte turns even more and heads almost due south for about 10 miles (16 km). About 30 miles (48 km) east-southeast of Waterloo and about 30 miles (48 km) from the Platte's confluence with the Missouri River ,

4692-469: The Platte were French explorers and fur trappers about 1714; they first called it the Nebraskier (Nebraska), a transliteration of the name given by the Otoe people, meaning "flat water". This expression is very close to the French words "rivière platte" ("flat river"), the probable origin of the name Platte River. The Platte River is formed in western Nebraska east of the city of North Platte, Nebraska by

4794-592: The Platte, North Platte River and Sweetwater River was first written about after its discovery in 1811 by Wilson Price Hunt of the Astor Expedition . He was returning to the Missouri River posts from the newly established Fort Astoria on the Columbia River near the Pacific Ocean. Because few American trappers and settlers were then in the contested Oregon Territory , his trail discovery

4896-425: The South Platte River. The upper reaches of the river in the Rockies in Colorado and Wyoming are popular for recreation rafting and lure and fly fishing for rainbow , brown , cutthroat trout and other sport fish. In western Nebraska, the banks and riverbed of the North Platte provide a green oasis amid an otherwise semi-arid region of North America. Today, by the time the North Platte reaches Paxton, Nebraska it

4998-418: The South and Middle fork join, the South Platte flows east-southeast till it exits Elevenmile Reservoir; it turns almost ninety degrees to skirt the west side of Pikes Peak and flows roughly east-northeast about 100 miles (160 km) through Denver and on to Greeley, Colorado . From Greeley, the South Platte turns east and flows about 200 miles (320 km) to its confluence with the North Platte River near

5100-446: The US initially had little interest in settling the land on the plains. The next "good" land was believed to be in Oregon or California , especially the coastal areas, and those were the destinations of most emigrant traffic. The Mormons settled Utah , largely due to religious persecution in eastern areas. Various gold and silver strikes attracted further emigration to nearly all western states. The Native American trail west along

5202-417: The US, interstate compacts ) or other political entities in a particular drainage basin to manage the body or bodies of water into which it drains. Examples of such interstate compacts are the Great Lakes Commission and the Tahoe Regional Planning Agency . In hydrology , the drainage basin is a logical unit of focus for studying the movement of water within the hydrological cycle . The process of finding

5304-450: The ability of its groundwater to sustain them. Varying cultures of indigenous peoples lived intermittently along the Platte for thousands of years before European exploration. Historical tribes claimed various territories in the region. The Indian tribes typically visited different areas in different seasons, as they followed the bison herds for hunting periods. The introduction of horses, which had escaped from early Spanish explorers in

5406-421: The area west of the Mississippi River to the US in the Louisiana Purchase ; the US roughly doubled its area at a cost of about $ 15,000,000. In 1820 the U.S. Army ordered Major Stephen H. Long to explore and map the area around the Platte. Long reported the area as a great American desert, despite its native inhabitants and wildlife, due to a lack of easily-cultivated land. As a result of his and other reports,

5508-658: The balance is for labor, because of the project's high standards and the rigors of working for a maximum of 6 + 1 ⁄ 2  hours per day at such a high altitude during a short season of April to October. Heavy equipment and prefabricated building components are slowly moved up the mountain's highway in the middle of the night to avoid any car traffic. Ground conditions are bedrock and alpine permafrost , soil and rock that remains at or below freezing temperatures all year to depths of up to 200 feet (61 m), only warming above freezing in direct sunlight or due to external sources. Problems with excavation and blasting exist because

5610-406: The basin, it can form tributaries that change the structure of the land. There are three different main types, which are affected by the rocks and ground underneath. Rock that is quick to erode forms dendritic patterns, and these are seen most often. The two other types of patterns that form are trellis patterns and rectangular patterns. Rain gauge data is used to measure total precipitation over

5712-479: The city of North Platte, Nebraska. The South Platte River has been dammed about 20 times for water storage, drinking water and irrigation purposes in Colorado as it flows to its confluence with the North Platte River. The total number of dams in the South Platte drainage may exceed 1,000 as nearly all major streams have at least one dam on them. The South Platte River serves as the principal source of water for arid eastern Colorado. The South Platte River valley provided

5814-407: The confluence of the North Platte and the South Platte Rivers , which both arise from snowmelt in the eastern Rockies east of the Continental Divide . In central north Colorado is the North Park valley, ringed by mountains of 12,000 feet (3,700 m) height; this is where the North Platte River originates. The head of the North Platte River is essentially all of Jackson County ; its boundaries are

The rugged Rocky Mountains Continental Divide surrounding Jackson County have at least twelve peaks over 11,000 feet (3,400 m) in height. From Jackson County, the North Platte flows north about 200 miles (320 km) out of

6018-423: The current Summit House. The older facility will remain open to the more than 600,000 visitors annually through the end of construction in the fall of 2020 or summer of 2021. Around 40 contractors are working on the $ 50 million project. The general contractor, G.E. Johnson Construction Co., estimates that about half of the budget is for materials, many of which are prefabricated in downslope shops, and

6120-430: The discharge of water from a basin may be made by a stream gauge located at the basin's outlet. Depending on the conditions of the drainage basin, as rainfall occurs some of it seeps directly into the ground. This water will either remain underground, slowly making its way downhill and eventually reaching the basin, or it will permeate deeper into the soil and consolidate into groundwater aquifers. As water flows through

6222-441: The drainage area is dependent on the soil type. Certain soil types such as sandy soils are very free-draining, and rainfall on sandy soil is likely to be absorbed by the ground. However, soils containing clay can be almost impermeable and therefore rainfall on clay soils will run off and contribute to flood volumes. After prolonged rainfall even free-draining soils can become saturated , meaning that any further rainfall will reach

This can cause eutrophication where plant growth is accelerated by the additional material. Because drainage basins are coherent entities in a hydrological sense, it has become common to manage water resources on the basis of individual basins. In the U.S. state of Minnesota , governmental entities that perform this function are called " watershed districts ". In New Zealand, they are called catchment boards. Comparable community groups based in Ontario, Canada, are called conservation authorities . In North America, this function

The five largest river basins (by area), from largest to smallest, are those of the Amazon (7 million km ), the Congo (4 million km ), the Nile (3.4 million km ), the Mississippi (3.22 million km ), and the Río de la Plata (3.17 million km ). The three rivers that drain

6528-408: The first irrigation ditch to divert water from the Platte for farming. In March 1924, the U.S. Army Air Corps conducted a three-day bombing campaign on an ice gorge that threatened bridges near the town of North Bend. The Platte is in the middle of the Central Flyway, a primary north–south corridor for migratory birds from their summer nesting grounds in the north ( Alaska and Canada ), south for

6630-458: The gravel and sediment that is constantly washed off the road into the alpine environment. In 2023, the toll road cost US$ 15 for age 16 and older or US$ 5 for age 6 to 15; from December 1 to April 30 the cost is reduced to US$ 10 for age 16 and older. The Highway is famous worldwide for the annual Pikes Peak International Hill Climb , a motor race held since 1916. The short film Climb Dance features Ari Vatanen racing his Peugeot 405 T16 up

The Mediterranean Sea basin, with the Black Sea , includes much of North Africa , east-central Africa (through the Nile River ), Southern , Central, and Eastern Europe , Turkey , and the coastal areas of Israel , Lebanon , and Syria . The Arctic Ocean drains most of Western Canada and Northern Canada east of

7140-683: The minting equipment for $ 25,000 (or $ 620,000 adjusted for inflation) to open the Denver Mint . Julia Archibald Holmes and James Holmes traveled to the Rocky Mountains in Colorado in 1858, and reached the summit on August 5, with J. D. Miller and George Peck, making Archibald Holmes the first European-American woman to climb Pikes Peak. From the summit, she wrote in a letter to her mother: "Nearly everyone tried to discourage me from attempting it, but I believed that I should succeed; and now here I am, and I feel that I would not have missed this glorious sight for anything at all." Thirty-five years later, in July 1893, Katharine Lee Bates wrote

7242-413: The most northern of Spanish exploration trips into the central plains. A Pawnee and Otoe Indian attack defeated the Spanish forces; the survivors returned to Santa Fe, New Mexico , and the Spanish left the Great Plains to the American Indians. As a result of the Seven Years' War (1756–1763) (called the French and Indian War in America), the French ceded all of their lands in North America east of

7344-462: The most water, from most to least, are the Amazon, Ganges , and Congo rivers. Endorheic basin are inland basins that do not drain to an ocean. Endorheic basins cover around 18% of the Earth's land. Some endorheic basins drain to an Endorheic lake or Inland sea . Many of these lakes are ephemeral or vary dramatically in size depending on climate and inflow. If water evaporates or infiltrates into

7446-426: The mountain "El Capitán," meaning "The Leader". American explorer Zebulon Pike named the mountain "Highest Peak" in 1806, and the mountain was later commonly known as "Pike's Highest Peak." American explorer Stephen Harriman Long named the mountain "James Peak" in honor of Edwin James who climbed to the summit during Long's Expedition of 1820 . The mountain was later renamed "Pike's Peak" in honor of Pike. The name

At the peak, the partial pressure of oxygen is only about 60% of that at sea level. Water boils at 186 °F (86 °C) at 14,000 feet, rather than 212 °F (100 °C) at sea level. A faster rate of respiration

7650-421: The mountain. The Manitou and Pike's Peak Railway , the world's highest cog railroad , operated from Manitou Springs to the summit, closed for repairs in 2017. After being closed for more than three years, the cog railway resumed service seven days per week (conditions permitting) on May 27, 2021. Road vehicles can be driven to the summit via the Pikes Peak Highway , a 19 mi (31 km) road that starts

7752-729: The north and south banks of the Platte and North Platte River were the Oregon (1843–1869), California (1843–1869), Mormon (1847–1869) and the Bozeman (1863–68) trails. This network of trails, sometimes called the Emigrant Trails or the Great Platte River Road , all went west along both sides of the Platte River. The route along the Platte River included all these emigration trails and was developed as an important trail route used by migrant wagon trains for westward United States expansion after 1841. The settlement of

7854-419: The numbers have declined. Canada geese have adapted to the farm fields and scavenge a large part of their fare from unharvested grain. Many have taken up residence at suburban office parks and stopped seasonal migrations. The Platte River flowing through an arid part of the mid-west has been widely overused. The claims on the Platte River water have exceeded the supply of water in drier years. Under Nebraska law,

7956-539: The permafrost in the fractured granite actually absorbs energy. The project is being constructed to achieve both Leadership in Energy and Environmental Design (LEED) Platinum Certification and Living Building Challenge . The new complex will include a visitor center, a communications facility for Colorado Springs Utilities, and the Army's High-Altitude Research Laboratory. On July 20, 2023, an EF1 tornado touched down on

8058-418: The rainfall on the area of land included in its polygon. These polygons are made by drawing lines between gauges, then making perpendicular bisectors of those lines form the polygons. The isohyetal method involves contours of equal precipitation are drawn over the gauges on a map. Calculating the area between these curves and adding up the volume of water is time-consuming. Isochrone maps can be used to show

8160-478: The relief botanist for Stephen Harriman Long 's expedition after the first botanist had died. The expedition explored the South Platte River up as far as present-day Denver, then turned south and passed close to what James called "Pike's highest peak". James and two other men left the expedition, camped on the plains, and climbed the peak in two days, encountering little difficulty. Along the way, James

8262-631: The responsibility of the countries sharing it. Nile Basin Initiative , OMVS for Senegal River , Mekong River Commission are a few examples of arrangements involving management of shared river basins. Management of shared drainage basins is also seen as a way to build lasting peaceful relationships among countries. The catchment is the most significant factor determining the amount or likelihood of flooding . Catchment factors are: topography , shape, size, soil type, and land use (paved or roofed areas). Catchment topography and shape determine

8364-461: The river rather than being absorbed by the ground. If the surface is impermeable the precipitation will create surface run-off which will lead to higher risk of flooding; if the ground is permeable, the precipitation will infiltrate the soil. Land use can contribute to the volume of water reaching the river, in a similar way to clay soils. For example, rainfall on roofs, pavements , and roads will be collected by rivers with almost no absorption into

8466-406: The river system, both for human use and for the sake of the basin's endangered species. As of October 2009, the study is still ongoing. Drainage basin A drainage basin is an area of land in which all flowing surface water converges to a single point, such as a river mouth , or flows into another body of water , such as a lake or ocean . A basin is separated from adjacent basins by

8568-681: The song " America the Beautiful ", after having admired the view from the top of Pikes Peak. It appeared in print in The Congregationalist , a weekly journal, on July 4, 1895. A plaque commemorating the words to the song was placed at the summit. On July 17, 1913 William Wayne Brown drove his car, the Bear Cat , 20 miles (32 km) to the summit. The ascent took 5 hours and 28 minutes. The uppermost portion of Pikes Peak, above 14,000 feet (4,267 m) elevation,

8670-418: The speed with which the runoff reaches a river. A long thin catchment will take longer to drain than a circular catchment. Size will help determine the amount of water reaching the river, as the larger the catchment the greater the potential for flooding. It is also determined on the basis of length and width of the drainage basin. Soil type will help determine how much water reaches the river. The runoff from

8772-751: The steep, twisty slopes. It also hosts the Pikes Peak Cycling Hill Climb (formerly Assault on the Peak), a cycling hillclimb race first held in 2010, and the USA Cycling Hill Climb National Championships, a race first held in 2016. The most popular hiking route to the top is called Barr Trail , which approaches the summit from the east. The trailhead is just past the cog railway depot in Manitou Springs. Visitors can walk, hike, or bike

8874-654: The summit from the west. Barr Trail can also be accessed via the Manitou Incline . Since the end of 1922, the AdAmAn Club, a mountaineering group, climb the Barr Trail on the east face of Pikes Peak each year on December 30th, stay overnight at Barr Camp, and continue to the top on December 31. Then, at midnight on New Year's Eve, the AdAmAn members and their guests ignite a fireworks display from

8976-526: The summit. Since 1969, the summit of Pikes Peak has been the site of the United States Army Pikes Peak Research Laboratory , a medical research laboratory for the assessment of the impact of high altitude on human physiological and medical parameters of military interest. On June 4, 2018, ground-breaking was held for a new 38,000 square feet (3,500 m ) Summit Complex which is being constructed next to

9078-415: The time taken for rain to reach the river, while catchment size, soil type, and development determine the amount of water to reach the river. Generally, topography plays a big part in how fast runoff will reach a river. Rain that falls in steep mountainous areas will reach the primary river in the drainage basin faster than flat or lightly sloping areas (e.g., > 1% gradient). Shape will contribute to

9180-477: The time taken for runoff water within a drainage basin to reach a lake, reservoir or outlet, assuming constant and uniform effective rainfall. Drainage basins are the principal hydrologic unit considered in fluvial geomorphology . A drainage basin is the source for water and sediment that moves from higher elevation through the river system to lower elevations as they reshape the channel forms. Drainage basins are important in ecology . As water flows over

9282-539: The trail. Although the Barr Trail is rated only Class 1, it is a long and arduous hike with nearly 8,000 ft (2,400 m) of elevation gain, and a 13 mi (21 km) trip one-way. The Pikes Peak Marathon , a trail race held since 1956, is a round trip between the trailhead and the Pikes Peak. The Barr Trail Mountain Race is a 13 miles (21 km) round trip between the trailhead and Barr Camp. Another route, rated as Class 2, begins at Crags Campground, approaching

9384-613: The trail. On their return trip, the fur traders carried out furs destined for eastern markets. The fur trade route was used to about 1840. By about 1832, the fur traders had improved the trail along the Platte, North Platte, and Sweetwater rivers to a rough wagon trail from the Missouri River to the Green River in Wyoming, where most of the Rocky Mountain Rendezvous were held. In 1834 Benjamin Bonneville ,

9486-549: The trails along the Platte. The Pony Express , operational from 1860–61, and the First Transcontinental Telegraph , completed in 1861, both followed the earlier emigrant trails along the Platte. The completion of the telegraph put the Pony Express out of business as it could provide much faster east–west communication. In 1866 the Union Pacific portion of the first Transcontinental Railroad

9588-412: The winter, and the return in the spring. The Central Flyway bird species include trumpeter swans , tundra swans , over one million Canada geese , greater white-fronted geese , sandhill cranes, canvasback ducks and others. Other species such as bald eagles , herons and several species of ducks migrate through the Platte River area but over shorter distances. The whooping crane, piping plover , and

9690-729: The world's land drains to the Atlantic Ocean . In North America , surface water drains to the Atlantic via the Saint Lawrence River and Great Lakes basins, the Eastern Seaboard of the United States, the Canadian Maritimes , and most of Newfoundland and Labrador . Nearly all of South America east of the Andes also drains to the Atlantic, as does most of Western and Central Europe and

9792-581: Was constructed along the Platte River as it started west from Omaha. In the 20th century, the Lincoln Highway and later Interstate 80 were constructed through the Platte valley. The highways parallel the Platte and the North Platte through much of Nebraska. Many of Nebraska’s larger cities originated on or near the Platte River, as it was the first path of transportation. These include Omaha (est. 1854), Fort Kearny (est. 1848), Grand Island (est. 1857) and North Platte (est. 1869). In 1859 settlers built

9894-624: Was declared a National Historic Landmark in 1961. Pikes Peak was the home of a ski resort from 1939 until 1984. There are several visitor centers on Pikes Peak, some with a gift shop and restaurant. These centers are located at the 6-mile (9.7 km) and 12-mile (19 km) markers of the toll road, plus one at the summit itself. Along with other food, the Summit House sells special high altitude doughnuts , frying up to 700 per hour. The doughnuts collapse or go mushy if transported to lower altitudes. There are several ways to ascend

9996-485: Was little used and nearly forgotten. In 1823 Jedediah Smith and several trappers "rediscovered" the route. The trail along the Platte, North Platte and Sweetwater rivers became a major route of fur traders to their summer Rocky Mountain Rendezvous . In 1824 fur trappers and traders directing mule trains carrying trade goods and supplies for the mountain men were some of the first European-American parties to use

10098-533: Was silty and bad tasting, but it was usable if no other water was available. Emigrants learned to let it sit in a bucket for an hour or so to settle most of the silt. The trail(s) through the Platte River Valley extended about 450 miles (720 km) in the present state of Nebraska. Nearly all the trails from the Missouri converged on the Platte River at or before Fort Kearny in mid-state Nebraska. Historians have estimated about 400,000 emigrants followed

10200-513: Was simplified to "Pikes Peak" by the United States Board on Geographic Names in 1890. Pikes Peak is one of Colorado's 54  fourteeners , mountains more than 14,000 feet (4,267.2 m) above sea level. The massif rises over 8,000 ft (2,400 m) above downtown Colorado Springs. Pikes Peak is a designated National Historic Landmark . It is composed of a characteristic pink granite called Pikes Peak granite . The color

10302-434: Was that the Platte was "a mile wide at the mouth, but only six inches deep." 49ers said it was "too thick to drink, too thin to plow". In western Nebraska, the banks and riverbed of the Platte provide a green oasis amid an otherwise semi-arid region of North America. The central Platte River valley is an important stopover for migratory water birds, such as the whooping crane and sandhill crane , in their yearly traversal of

10404-568: Was the first to describe the blue columbine , Colorado's state flower. Gold was discovered in the area of present-day Denver in 1858, and newspapers referred to the gold-mining area as "Pike's Peak". Pike's Peak or Bust became the slogan of the Colorado Gold Rush (see also Fifty-Niner ). This was more due to Pikes Peak's visibility to gold seekers traveling west across the plains than any actual significant gold find anywhere near Pikes Peak. Major gold deposits were not discovered in
