Wyoming
Wyoming is a landlocked state in the Mountain West subregion of the Western United States. It borders Montana to the north and northwest, South Dakota and Nebraska to the east, Idaho to the west, Utah to the southwest, and Colorado to the south. With an estimated population of 587,618 as of 2024, Wyoming is the least populous state despite being the tenth-largest by area, and it has the second-lowest population density. The state capital and most populous city is Cheyenne.
Wyoming's western half consists mostly of the ranges and rangelands of the Rocky Mountains; its eastern half consists of high-elevation prairie, and is referred to as the High Plains. Wyoming's climate is semi-arid in some parts and continental in others, making it drier and windier overall than other states, with greater temperature extremes. The federal government owns just under half of Wyoming's land; the state ranks sixth in the amount of land—and fifth in the proportion of its land—that is owned by the federal government. Its federal lands include two national parks, two national recreation areas, two national monuments, and several national forests, as well as historic sites, fish hatcheries, and wildlife refuges.
Indigenous peoples have inhabited the region for thousands of years. Part of the land that became Wyoming came under American sovereignty via the Louisiana Purchase, part via the Oregon Treaty, and, lastly, via the Mexican Cession. With the opening of the Oregon Trail, the Mormon Trail, and the California Trail, vast numbers of pioneers traveled through parts of the state that had once been traversed mainly by fur trappers, and this spurred the establishment of forts, such as Fort Laramie, that today serve as population centers. The Transcontinental Railroad supplanted the wagon trails in 1867 with a route through southern Wyoming, bringing new settlers and the establishment of founding towns, including the state capital of Cheyenne. On July 10, 1890, Wyoming became the union's 44th state. Wyoming was the first state to allow women the right to vote doing so since it was territory in 1869, and achieving statehood in 1890. It was also the first state to grant women the right to assume elected office, as well as the first state to elect a female governor, Nellie Tayloe Ross. In honor of this part of its history, its official nickname is "The Equality State" and its official state motto is "Equal Rights".
Farming and ranching, and the attendant range wars, feature prominently in the state's history. Wyoming's economy is largely based on tourism and the extraction of minerals such as coal, natural gas, oil, and trona. Its agricultural commodities include barley, hay, livestock, sugar beets, wheat, and wool.
Etymology
The region had acquired the name Wyoming by 1865 when Representative James Mitchell Ashley of Ohio introduced a bill to Congress to provide a "temporary government for the territory of Wyoming". The territory was named after the Wyoming Valley in Pennsylvania. Thomas Campbell wrote his 1809 poem "Gertrude of Wyoming", inspired by the Battle of Wyoming in the American Revolutionary War. The name ultimately derives from the Lenape Munsee word xwé:wamənk.History
Several Native American groups originally inhabited the region today known as Wyoming. The Crow, Arapaho, Lakota, and Shoshone were but a few of the original inhabitants European explorers encountered when they first visited the region. What is now southwestern Wyoming was claimed by the Spanish Empire, which extended through the Southwest and Mexico. With Mexican independence in 1821, it was considered part of Alta California. U.S. expansion brought settlers who fought for control. Mexico ceded these territories after its defeat in 1848 in the Mexican–American War.From the late 18th century, French-Canadian trappers from Québec and Montréal regularly entered the area for trade with the tribes. French toponyms such as Téton and La Ramie are marks of that history.
American John Colter first recorded a description in English of the region in 1807. He was a member of the Lewis and Clark Expedition, which was guided by French Canadian Toussaint Charbonneau and his young Shoshone wife, Sacagawea. At the time, Colter's reports of the Yellowstone area were considered fictional. On a return from Astoria, Robert Stuart and a party of five men discovered South Pass in 1812.
The Oregon Trail later followed that route as emigrants moved to the west coast. In 1850, mountain man Jim Bridger first documented what is now known as Bridger Pass. Bridger also explored Yellowstone, and filed reports on the region that, like Colter's, were largely regarded at the time as tall tales. The Union Pacific Railroad constructed track through Bridger Pass in 1868. It was used as the route for construction of Interstate 80 through the mountains 90 years later.
After the Union Pacific Railroad reached Cheyenne in 1867, population growth was stimulated. The federal government established the Wyoming Territory on July 25, 1868. Lacking significant deposits of gold and silver, unlike mineral-rich Colorado, Wyoming did not have such a population boom. But South Pass City had a short-lived boom after the Carissa Mine began producing gold in 1867. Copper was mined in some areas between the Sierra Madre Mountains and the Snowy Range near Grand Encampment.
Once government-sponsored expeditions to the Yellowstone country began, Colter's and Bridger's descriptions of the region's landscape were confirmed. In 1872, Yellowstone National Park was created as the world's first, to protect this area. Nearly all of the park lies within the northwestern corner of Wyoming.
On December 10, 1869, territorial Governor John Allen Campbell extended the right to vote to women, making Wyoming the first territory to do so, and upon statehood became the first state to grant women's suffrage. Women first served on juries in Wyoming. Wyoming was also a pioneer in welcoming women into electoral politics. It had the first female court bailiff, and the first female justice of the peace in the country. In 1924, Wyoming was the first state to elect a female governor, Nellie Tayloe Ross, who took office in January 1925. Due to its civil-rights history, one of Wyoming's state nicknames is "The Equality State", and the official state motto is "Equal Rights".
Wyoming's constitution also included a pioneering article on water rights. Bills for Wyoming Territory's admission to the union were introduced in both the U.S. Senate and U.S. House of Representatives in December 1889. On March 27, 1890, the House passed the bill and President Benjamin Harrison signed Wyoming's statehood bill; Wyoming became the 44th state in the union on July 10, 1890.
Wyoming was the location of the Johnson County War of 1892, which erupted between competing groups of cattle ranchers. The passage of the Homestead Act led to an influx of small ranchers. A range war broke out when either or both of the groups chose violent conflict over commercial competition in the use of the public land.
Geography
Climate
Wyoming's climate is generally semi-arid and continental and 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 in most of the state. With increasing elevation, however, this average drops rapidly with locations above averaging around. Summer nights throughout the state are characterized by a rapid cooldown with even the hottest locations averaging in the range at night. In most of the state, most of the precipitation tends to fall in the late spring and early summer. Winters are cold but are variable with periods of sometimes extreme cold interspersed between generally 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 of rainfall per year. Precipitation depends on elevation with lower areas in the Big Horn Basin averaging, making the area nearly a true desert. The lower areas in the North and on the eastern plains typically average around, making the climate there semi-arid. Some mountain areas do receive a good amount of precipitation, or more, much of it as snow, sometimes or more annually. The state's highest recorded temperature is at Basin on July 12, 1900, and the lowest recorded temperature is at Riverside on February 9, 1933.
The number of thunderstorm days varies 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 the late spring and 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 dramatically 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.
