Wyoming is a state in the mountain region of the western United States. The state is the 10th largest by area, the least populous, the second most sparsely populated state in the country. Wyoming is bordered on the north by Montana, on the east by South Dakota and Nebraska, on the south by Colorado, on the southwest by Utah, on the west by Idaho and Montana; the state population was estimated at 577,737 in 2018, less than 31 of the most populous U. S. cities including Denver in neighboring Colorado. Cheyenne is the state capital and the most populous city, with an estimated population of 63,624 in 2017; the western two-thirds of the state is covered by the mountain ranges and rangelands of the Rocky Mountains, while the eastern third of the state is high elevation prairie called the High Plains. Half of the land in Wyoming is owned by the U. S. government, leading Wyoming to rank sixth by area and fifth by proportion of a state's land owned by the federal government. Federal lands include two national parks—Grand Teton and Yellowstone—two national recreation areas, two national monuments, several national forests, historic sites, fish hatcheries, wildlife refuges.
Original inhabitants of the region include the Crow, Arapaho and Shoshone. Southwestern Wyoming was in the Spanish Empire and Mexican territory until it was ceded to the United States in 1848 at the end of the Mexican–American War; the region acquired the name Wyoming when a bill was introduced to the U. S. Congress in 1865 to provide a "temporary government for the territory of Wyoming"; the name was used earlier for the Wyoming Valley in Pennsylvania, is derived from the Munsee word xwé:wamənk, meaning "at the big river flat". The main drivers of Wyoming's economy are mineral extraction—mostly coal, natural gas, trona—and tourism. Agricultural commodities include livestock, sugar beets and wool; the climate is semi-arid and continental and windier than the rest of the U. S. with greater temperature extremes. Wyoming has been a politically conservative state since the 1950s, with the Republican Party candidate winning every presidential election except 1964. Wyoming's climate is semi-arid and continental, is drier and windier in comparison to most of the United States with greater temperature extremes.
Much of this is due to the topography of the state. Summers in Wyoming are warm with July high temperatures averaging between 85 and 95 °F in most of the state. With increasing elevation, this average drops with locations above 9,000 feet averaging around 70 °F. Summer nights throughout the state are characterized by a rapid cooldown with the hottest locations averaging in the 50–60 °F range at night. In most of the state, most of the precipitation tends to fall in early summer. Winters are cold, but are variable with periods of sometimes extreme cold interspersed between mild periods, with Chinook winds providing unusually warm temperatures in some locations. Wyoming is a dry state with much of the land receiving less than 10 inches of rainfall per year. Precipitation depends on elevation with lower areas in the Big Horn Basin averaging 5–8 inches; the lower areas in the North and on the eastern plains average around 10–12 inches, making the climate there semi-arid. Some mountain areas do receive a good amount of precipitation, 20 inches or more, much of it as snow, sometimes 200 inches or more annually.
The state's highest recorded temperature is 114 °F at Basin on July 12, 1900 and the lowest recorded temperature is −66 °F at Riverside on February 9, 1933. The number of thunderstorm days vary across the state with the southeastern plains of the state having the most days of thunderstorm activity. Thunderstorm activity in the state is highest during early summer; the southeastern corner of the state is the most vulnerable part of the state to tornado activity. Moving away from that point and westwards, the incidence of tornadoes drops with the west part of the state showing little vulnerability. Tornadoes, where they occur, tend to be small and brief, unlike some of those that occur farther east; as specified in the designating legislation for the Territory of Wyoming, Wyoming's borders are lines of latitude 41°N and 45°N, longitude 104°3'W and 111°3'W, making the shape of the state a latitude-longitude quadrangle. Wyoming is one of only three states to have borders along only straight latitudinal and longitudinal lines, rather than being defined by natural landmarks.
Due to surveying inaccuracies during the 19th century, Wyoming's legal border deviates from the true latitude and longitude lines by up to half of a mile in some spots in the mountainous region along the 45th parallel. Wyoming is bordered on the north by Montana, on the east by South Dakota and Nebraska, on the south by Colorado, on the southwest by Utah, on the west by Idaho, it is the tenth largest state in the United States in total area, containing 97,814 square miles and is made up of 23 counties. From the north border to the south border it is 276 miles; the Great Plains meet the Rocky Mountains in Wyoming. The state is a great plateau broken by many mountain ranges. Surface elevations range from the summit of Gannett Peak in the Wind River Mountain Range, at 13,804 feet, to the Belle Fourche River val
Native Americans in the United States
Native Americans known as American Indians, Indigenous Americans and other terms, are the indigenous peoples of the United States, except Hawaii. There are over 500 federally recognized tribes within the US, about half of which are associated with Indian reservations; the term "American Indian" excludes Native Hawaiians and some Alaska Natives, while Native Americans are American Indians, plus Alaska Natives of all ethnicities. Native Hawaiians are not counted as Native Americans by the US Census, instead being included in the Census grouping of "Native Hawaiian and other Pacific Islander"; the ancestors of modern Native Americans arrived in what is now the United States at least 15,000 years ago much earlier, from Asia via Beringia. A vast variety of peoples and cultures subsequently developed. Native Americans were affected by the European colonization of the Americas, which began in 1492, their population declined precipitously due to introduced diseases as well as warfare, territorial confiscation and slavery.
After the founding of the United States, many Native American peoples were subjected to warfare and one-sided treaties, they continued to suffer from discriminatory government policies into the 20th century. Since the 1960s, Native American self-determination movements have resulted in changes to the lives of Native Americans, though there are still many contemporary issues faced by Native Americans. Today, there are over five million Native Americans in the United States, 78% of whom live outside reservations; when the United States was created, established Native American tribes were considered semi-independent nations, as they lived in communities separate from British settlers. The federal government signed treaties at a government-to-government level until the Indian Appropriations Act of 1871 ended recognition of independent native nations, started treating them as "domestic dependent nations" subject to federal law; this law did preserve the rights and privileges agreed to under the treaties, including a large degree of tribal sovereignty.
For this reason, many Native American reservations are still independent of state law and actions of tribal citizens on these reservations are subject only to tribal courts and federal law. The Indian Citizenship Act of 1924 granted U. S. citizenship to all Native Americans born in the United States. This emptied the "Indians not taxed" category established by the United States Constitution, allowed natives to vote in state and federal elections, extended the Fourteenth Amendment protections granted to people "subject to the jurisdiction" of the United States. However, some states continued to deny Native Americans voting rights for several decades. Bill of Rights protections do not apply to tribal governments, except for those mandated by the Indian Civil Rights Act of 1968. Since the end of the 15th century, the migration of Europeans to the Americas has led to centuries of population and agricultural transfer and adjustment between Old and New World societies, a process known as the Columbian exchange.
As most Native American groups had preserved their histories by oral traditions and artwork, the first written sources of the conflict were written by Europeans. Ethnographers classify the indigenous peoples of North America into ten geographical regions with shared cultural traits, called cultural areas; some scholars combine the Plateau and Great Basin regions into the Intermontane West, some separate Prairie peoples from Great Plains peoples, while some separate Great Lakes tribes from the Northeastern Woodlands. The ten cultural areas are as follows: Arctic, including Aleut and Yupik peoples Subarctic Northeastern Woodlands Southeastern Woodlands Great Plains Great Basin Northwest Plateau Northwest Coast California Southwest At the time of the first contact, the indigenous cultures were quite different from those of the proto-industrial and Christian immigrants; some Northeastern and Southwestern cultures, in particular, were matrilineal and operated on a more collective basis than that with which Europeans were familiar.
The majority of Indigenous American tribes maintained their hunting grounds and agricultural lands for use of the entire tribe. Europeans at that time had patriarchal cultures and had developed concepts of individual property rights with respect to land that were different; the differences in cultures between the established Native Americans and immigrant Europeans, as well as shifting alliances among different nations in times of war, caused extensive political tension, ethnic violence, social disruption. Before the European settlement of what is now the United States, Native Americans suffered high fatalities from contact with new European diseases, to which they had not yet acquired immunity. Smallpox epidemics are thought to have caused the greatest loss of life for indigenous populations. William M Denevan, noted author and Professor Emeritus of Geography at the University of Wisconsin-Madison, said on this subject in his essay "The Pristine Myth: The Landscape of the Americas in 1492".
Old World diseases were the primary killer. In many regions the tropical lowlands, populations fell by 90 percent or more in the first century after the contact. "Estimates of the pre-Columbian population of what today constitutes the U. S. vary ranging from William M Denevan's 3.8 million in his 1992 w
Sierra Nevada (U.S.)
The Sierra Nevada is a mountain range in the Western United States, between the Central Valley of California and the Great Basin. The vast majority of the range lies in the state of California, although the Carson Range spur lies in Nevada; the Sierra Nevada is part of the American Cordillera, a chain of mountain ranges that consists of an continuous sequence of such ranges that form the western "backbone" of North America, Central America, South America and Antarctica. The Sierra runs 400 miles north-to-south, is 70 miles across east-to-west. Notable Sierra features include the largest alpine lake in North America; the Sierra is home to three national parks, twenty wilderness areas, two national monuments. These areas include Yosemite and Kings Canyon National Parks; the character of the range is shaped by its ecology. More than one hundred million years ago during the Nevadan orogeny, granite formed deep underground; the range started to uplift four million years ago, erosion by glaciers exposed the granite and formed the light-colored mountains and cliffs that make up the range.
The uplift caused a wide range of elevations and climates in the Sierra Nevada, which are reflected by the presence of five life zones. Uplift continues due to faulting caused by tectonic forces, creating spectacular fault block escarpments along the eastern edge of the southern Sierra; the Sierra Nevada has a significant history. The California Gold Rush occurred in the western foothills from 1848 through 1855. Due to inaccessibility, the range was not explored until 1912; the Sierra Nevada lies in Central and Eastern California, with a small but important spur extending into Nevada. West-to-east, the Sierra Nevada's elevation increases from 1,000 feet in the Central Valley to heights of about 14,000 feet at its crest 50–75 miles to the east; the east slope forms the steep Sierra Escarpment. Unlike its surroundings, the range receives a substantial amount of snowfall and precipitation due to orographic lift; the Sierra Nevada's irregular northern boundary stretches from the Susan River and Fredonyer Pass to the North Fork Feather River.
It represents where the granitic bedrock of the Sierra Nevada dives below the southern extent of Cenozoic igneous surface rock from the Cascade Range. It is bounded on the west by California's Central Valley and on the east by the Basin and Range Province; the southern boundary is at Tehachapi Pass. Physiographically, the Sierra is a section of the Cascade-Sierra Mountains province, which in turn is part of the larger Pacific Mountain System physiographic division; the California Geological Survey states that "the northern Sierra boundary is marked where bedrock disappears under the Cenozoic volcanic cover of the Cascade Range." The range is drained on its western slope by the Central Valley watershed, which discharges into the Pacific Ocean at San Francisco. The northern third of the western Sierra is part of the Sacramento River watershed, the middle third is drained by the San Joaquin River; the southern third of the range is drained by the Kings, Kaweah and Kern rivers, which flow into the endorheic basin of Tulare Lake, which overflows into the San Joaquin during wet years.
The eastern slope watershed of the Sierra is much narrower. From north to south, the Susan River flows into intermittent Honey Lake, the Truckee River flows from Lake Tahoe into Pyramid Lake, the Carson River runs into Carson Sink, the Walker River into Walker Lake. Although none of the eastern rivers reach the sea, many of the streams from Mono Lake southwards are diverted into the Los Angeles Aqueduct which provides water to Southern California; the height of the mountains in the Sierra Nevada increases from north to south. Between Fredonyer Pass and Lake Tahoe, the peaks range from 5,000 feet to more than 9,000 feet; the crest near Lake Tahoe is 9,000 feet high, with several peaks approaching the height of Freel Peak. Farther south, the highest peak in Yosemite National Park is Mount Lyell; the Sierra rises to 14,000 feet with Mount Humphreys near Bishop, California. Near Lone Pine, Mount Whitney is at 14,505 feet, the highest point in the contiguous United States. South of Mount Whitney, the elevation of the range dwindles.
The crest elevation is 10,000 feet near Lake Isabella, but south of the lake, the peaks reach to only a modest 8,000 feet. There are several notable geographical features in the Sierra Nevada: Lake Tahoe is a large, clear freshwater lake in the northern Sierra Nevada, with an elevation of 6,225 ft and an area of 191 sq mi. Lake Tahoe lies between a spur of the Sierra. Hetch Hetchy Valley, Yosemite Valley, Kings Canyon, Kern Canyon are examples of many glacially-scoured canyons on the west side of the Sierra. Yosemite National Park is filled with notable features such as waterfalls, granite domes, high mountains and meadows. Groves of Giant Sequoia
Nevada is a state in the Western United States. It is bordered by Oregon to the northwest, Idaho to the northeast, California to the west, Arizona to the southeast and Utah to the east. Nevada is the 7th most extensive, the 32nd most populous, but the 9th least densely populated of the U. S. states. Nearly three-quarters of Nevada's people live in Clark County, which contains the Las Vegas–Paradise metropolitan area where three of the state's four largest incorporated cities are located. Nevada's capital, however, is Carson City. Nevada is known as the "Silver State" because of the importance of silver to its history and economy, it is known as the "Battle Born State", because it achieved statehood during the Civil War. Nevada is desert and semi-arid, much of it within the Great Basin. Areas south of the Great Basin are within the Mojave Desert, while Lake Tahoe and the Sierra Nevada lie on the western edge. About 86% of the state's land is managed by various jurisdictions of the U. S. federal government, both civilian and military.
Before European contact, Native Americans of the Paiute and Washoe tribes inhabited the land, now Nevada. The first Europeans to explore the region were Spanish, they called the region Nevada because of the snow. The area formed part of the Viceroyalty of New Spain, became part of Mexico when it gained independence in 1821; the United States annexed the area in 1848 after its victory in the Mexican–American War, it was incorporated as part of Utah Territory in 1850. The discovery of silver at the Comstock Lode in 1859 led to a population boom that became an impetus to the creation of Nevada Territory out of western Utah Territory in 1861. Nevada became the 36th state on October 31, 1864, as the second of two states added to the Union during the Civil War. Nevada has a reputation for its libertarian laws. In 1940, with a population of just over 110,000 people, Nevada was by far the least-populated state, with less than half the population of the next least-populated state. However, legalized gambling and lenient marriage and divorce laws transformed Nevada into a major tourist destination in the 20th century.
Nevada is the only U. S. state where prostitution is legal, though it is illegal in Clark County, Washoe County and Carson City. The tourism industry remains Nevada's largest employer, with mining continuing as a substantial sector of the economy: Nevada is the fourth-largest producer of gold in the world; the name "Nevada" comes from meaning "snow-covered", after the Sierra Nevada. Most Nevadans pronounce the second syllable of their state name using the TRAP vowel. Many from outside the Western United States pronounce it with the PALM vowel. Although the latter pronunciation is closer to the Spanish pronunciation, it is not the pronunciation preferred by most Nevadans. State Assemblyman Harry Mortenson proposed a bill to recognize the alternate pronunciation of Nevada, though the bill was not supported by most legislators and never received a vote; the Nevadan pronunciation is the de facto official one, since it is the one used by the state legislature. At one time, the state's official tourism organization, TravelNevada, stylized the name of the state as "Nevăda", with a breve mark over the a indicating the locally preferred pronunciation, available as a license plate design.
Nevada is entirely within the Basin and Range Province, is broken up by many north-south mountain ranges. Most of these ranges have endorheic valleys between them, which belies the image portrayed by the term Great Basin. Much of the northern part of the state is within the Great Basin, a mild desert that experiences hot temperatures in the summer and cold temperatures in the winter. Moisture from the Arizona Monsoon will cause summer thunderstorms; the state's highest recorded temperature was 125 °F in Laughlin on June 29, 1994. The coldest recorded temperature was −52 °F set in San Jacinto in 1972, in the northeastern portion of the state; the Humboldt River crosses the state from east to west across the northern part of the state, draining into the Humboldt Sink near Lovelock. Several rivers drain from the Sierra Nevada eastward, including the Walker and Carson rivers. All of these rivers are endorheic basins, ending in Walker Lake, Pyramid Lake, the Carson Sink, respectively. However, not all of Nevada is within the Great Basin.
Tributaries of the Snake River drain the far north, while the Colorado River, which forms much of the boundary with Arizona, drains much of southern Nevada. The mountain ranges, some of which have peaks above 13,000 feet, harbor lush forests high above desert plains, creating sky islands for endemic species; the valleys are no lower in elevation than 3,000 feet, while some in central Nevada are above 6,000 feet. The southern third of the state, where the Las Vegas area is situated, is within the Mojave Desert; the area is closer to the Arizona Monsoon in the summer. The terrain is lower below 4,000 feet, creating conditions for hot summer days and cool to chilly winter nights. Nevada and California have by far the longest diagonal line as a state boundary at just over 400 miles; this line begins in Lake Tahoe nearly
Idaho is a state in the northwestern region of the United States. It borders the state of Montana to the east and northeast, Wyoming to the east and Utah to the south, Washington and Oregon to the west. To the north, it shares a small portion of the Canadian border with the province of British Columbia. With a population of 1.7 million and an area of 83,569 square miles, Idaho is the 14th largest, the 12th least populous and the 7th least densely populated of the 50 U. S. states. The state's capital and largest city is Boise. Idaho prior to European settlement was inhabited by Native American peoples, some of whom still live in the area. In the early 19th century, Idaho was considered part of the Oregon Country, an area disputed between the U. S. and the United Kingdom. It became U. S. territory with the signing of the Oregon Treaty of 1846, but a separate Idaho Territory was not organized until 1863, instead being included for periods in Oregon Territory and Washington Territory. Idaho was admitted to the Union on July 3, 1890, becoming the 43rd state.
Forming part of the Pacific Northwest, Idaho is divided into several distinct geographic and climatic regions. In the state's north, the isolated Idaho Panhandle is linked with Eastern Washington, with which it shares the Pacific Time Zone – the rest of the state uses the Mountain Time Zone; the state's south includes the Snake River Plain, while the south-east incorporates part of the Great Basin. Idaho is quite mountainous, contains several stretches of the Rocky Mountains; the United States Forest Service holds about 38 % of the most of any state. Industries significant for the state economy include manufacturing, mining and tourism. A number of science and technology firms are either headquartered in Idaho or have factories there, the state contains the Idaho National Laboratory, the country's largest Department of Energy facility. Idaho's agricultural sector supplies many products, but the state is best known for its potato crop, which comprises around one-third of the nationwide yield; the official state nickname is the "Gem State".
The name's origin remains a mystery. In the early 1860s, when the United States Congress was considering organizing a new territory in the Rocky Mountains, eccentric lobbyist George M. Willing suggested the name "Idaho", which he claimed was derived from a Shoshone language term meaning "the sun comes from the mountains" or "gem of the mountains". Willing claimed he had invented the name. Congress decided to name the area Colorado Territory when it was created in February 1861. Thinking they would get a jump on the name, locals named a community in Colorado "Idaho Springs". However, the name "Idaho" did not fall into obscurity; the same year Congress created Colorado Territory, a county called Idaho County was created in eastern Washington Territory. The county was named after a steamship named Idaho, launched on the Columbia River in 1860, it is unclear after Willing's claim was revealed. Regardless, part of Washington Territory, including Idaho County, was used to create Idaho Territory in 1863.
Despite this lack of evidence for the origin of the name, many textbooks well into the 20th century repeated as fact Willing's account the name "Idaho" derived from the Shoshone term "ee-da-how". A 1956 Idaho history textbook says:"Idaho" is a Shoshoni Indian exclamation; the word consists of three parts. The first is "Ee", which in English conveys the idea of "coming down"; the second is "dah", the Shoshoni stem or root for both "sun" and "mountain". The third syllable, "how", denotes the exclamation and stands for the same thing in Shoshoni that the exclamation mark does in the English language; the Shoshoni word is "Ee-dah-how", the Indian thought thus conveyed when translated into English means, "Behold! the sun coming down the mountain. An alternative etymology attributes the name to the Plains Apache word "ídaahę́", used in reference to The Comanche. Idaho borders six U. S. states and one Canadian province. The states of Washington and Oregon are to the west and Utah are to the south, Montana and Wyoming are to the east.
Idaho shares a short border with the Canadian province of British Columbia to the north. The landscape is rugged with some of the largest unspoiled natural areas in the United States. For example, at 2.3 million acres, the Frank Church-River of No Return Wilderness Area is the largest contiguous area of protected wilderness in the continental United States. Idaho is a Rocky Mountain state with scenic areas; the state has snow-capped mountain ranges, vast lakes and steep canyons. The waters of the Snake River rush through the deepest gorge in the United States. Shoshone Falls plunges down rugged cliffs from a height greater than Niagara Falls; the major rivers in Idaho are the Snake River, the Clark Fork/Pend Oreille River, the Clearwater River, the Salmon River. Other significant rivers include the Coeur d'Alene River, the Spokane River, the Boise River, the Payette River; the Salmon River empties into the Snake in Hells Canyon and forms the southern boundary of Nez Perce County on its north shore, of which Lewiston is the county seat.
The Port of Lewiston, at the confluence of the Clearwater and the Snake Rivers is the farthest inland seaport on the West Coast at 465 river miles from the Pacific at Astoria, Oregon. Idaho's highest point is 12,662 ft, in the Lost River Range north of Mackay. Idaho's lowest poi
The Shoshone or Shoshoni are a Native American tribe with four large cultural/linguistic divisions: Eastern Shoshone: Wyoming Northern Shoshone: southeastern Idaho Western Shoshone: Nevada, northern Utah Gosiute: western Utah, eastern NevadaThey traditionally speak the Shoshoni language, part of the Numic languages branch of the large Uto-Aztecan language family. The Shoshone were sometimes called the Snake Indians by neighboring tribes and early American explorers, their peoples have become members of federally recognized tribes throughout their traditional areas of settlement colocated with the Northern Paiute people of the Great Basin. The name "Shoshone" comes from a Shoshone word for high-growing grasses; some neighboring tribes call the Shoshone "Grass House People," based on their traditional homes made from sosoni. Shoshones call themselves Newe, meaning "People."Meriwether Lewis recorded the tribe as the "Sosonees or snake Indians" in 1805. The Shoshoni language is spoken by 1,000 people today.
It belongs to the Central Numic branch of the Uto-Aztecan language family. Speakers are scattered from central Nevada to central Wyoming; the largest numbers of Shoshoni speakers live on the federally recognized Duck Valley Indian Reservation, located on the border of Nevada and Idaho. Idaho State University offers Shoshoni-language classes; the Shoshone are a Native American tribe, who originated in the western Great Basin and spread north and east into present-day Idaho and Wyoming. By 1500, some Eastern Shoshone had crossed the Rocky Mountains into the Great Plains. After 1750, warfare and pressure from the Blackfoot, Lakota and Arapaho pushed Eastern Shoshone south and westward; some of them moved as far south as Texas, emerging as the Comanche by 1700. As more European-American settlers migrated west, tensions rose with the indigenous people over competition for territory and resources. Wars occurred throughout the second half of the 19th century; the Northern Shoshone, led by Chief Pocatello, fought during the 1860s with settlers in Idaho.
As more settlers encroached on Shoshone hunting territory, the natives raided farms and ranches for food, attacked immigrants. The warfare resulted in the Bear River Massacre, when US forces attacked and killed an estimated 410 Northwestern Shoshone, who were at their winter encampment. A large number of the dead were civilians, including women and children, deliberately killed by the soldiers; this was the highest number of deaths which the Shoshone suffered at the hands of United States forces. Allied with the Bannock, to whom they were related, the Shoshone fought against the United States in the Snake War from 1864 to 1868, they fought US forces together in 1878 in the Bannock War. In 1876, by contrast, the Shoshone fought alongside the U. S. Army in the Battle of the Rosebud against their traditional enemies, the Lakota and Cheyenne. In 1879 a band of 300 Eastern Shoshone became involved in the Sheepeater Indian War, it was the last Indian war fought in the Pacific Northwest region of the present-day United States.
In 1911 a small group of Bannock under a leader named Mike Daggett known as "Shoshone Mike," killed four ranchers in Washoe County, Nevada. The settlers went out after the Native Americans, they killed eight. They lost one man of Ed Hogle; the posse captured a woman. A rancher donated the partial remains of three adult males, two adult females, two adolescent males, three children to the Smithsonian Institution in Washington, DC for study. In 1994, the institution repatriated the remains to the Fort Hall Idaho Shoshone-Bannock Tribe. In 2008 the Northwestern Shoshone acquired the site of the Bear River Massacre and some surrounding land, they wanted to protect the holy land and to build a memorial to the massacre, the largest their nation had suffered. "In partnership with the American West Heritage Center and state leaders in Idaho and Utah, the tribe has developed public/private partnerships to advance tribal cultural preservation and economic development goals." They have become a leader in developing tribal renewable energy.
In 1845 the estimated population of Northern and Western Shoshone was 4,500, much reduced after they had suffered infectious disease epidemics and warfare. The completion of the First Transcontinental Railroad in 1869 was followed by European-American immigrants arriving in unprecedented numbers in the territory. In 1937 the Bureau of Indian Affairs counted 1,201 Western Shoshone; as of the 2000 census, some 12,000 persons identified as Shoshone. Shoshone people are divided into traditional bands based both on their homelands and primary food sources; these include: Eastern Shoshone people:Guchundeka', Buffalo Eaters Tukkutikka, Mountain Sheep Eaters, joined the Northern Shoshone Boho'inee', Pohogwe, Sage Grass people, Sagebrush Butte PeopleNorthern Shoshone people:Agaideka, Salmon Eaters, Snake River and Lemhi River Valley Doyahinee', Mountain people Kammedeka, Jack Rabbit Eaters, Snake River, Great Salt Lake Hukundüka, Porcupine Grass Seed Eaters, Wild Wheat Eaters synonymous with Kammitikka Tukudeka, Dukundeka', Sheep Eaters, Sawtooth Range, Idaho Yahandeka, Groundhog Eaters, lower Boise and Wiser RiversWestern Shoshone people:Kusiutta, Great Salt Desert and Great Salt Lake, UtahCedar Valley Goshute Deep Creek Goshute Rush Valley G
