The State of Wyoming (IPA: /waɪˈoʊmɪŋ/) is a state in the western region of the United States of America. The majority of the state is dominated by the mountain ranges and rangelands of the Rocky Mountain West, while the easternmost section of the state is a high altitude prairie region known as the High Plains. The tenth largest U.S. state by size, Wyoming is the least populous, with a U.S. Census estimated population of 522,830 in 2007, a 5.9% increase since 2000.[3] The capital and the most populous city of Wyoming is Cheyenne.

Geography

Location and Size

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, and on the west by Idaho. It is the tenth largest state in the United States in total area, containing 97,818 square miles (253,348 km²) and is made up of 23 counties. From the north border to the south border it is 276 miles (444 km); and from the east to the west border is 375 miles (603 km).

Mountain Ranges

The Great Plains meet the Rocky Mountains in Wyoming. The state is a great plateau broken by a number of mountain ranges. Surface elevations range from the summit of Gannett Peak in the Wind River Mountain Range, at 13,804 feet (4,207 m), to the Belle Fourche River Valley in the state’s northeast corner, at 3,125 feet (952 m). In the northwest are the Absaroka, Owl Creek, Gros Ventre, Wind River and the Teton ranges. In the north central are the Big Horn Mountains; in the northeast, the Black Hills; and in the southern region the Laramie, Snowy and Sierra Madre ranges.

The Snowy Range in the south central part of the state is an extension of the Colorado Rockies in both geology and appearance. The Wind River Range in the west central part of the state is remote and includes more than 40 mountain peaks in excess of 13,000 ft. tall in addition to Gannett Peak, the highest peak in the state. The Big Horn Mountains in the north central portion are somewhat isolated from the bulk of the Rocky Mountains.

The Teton Range in the northwest extends for 50 miles (80 km) and represents the most impressive section of mountains in the state. It is home to Grand Teton, the second highest peak in Wyoming, and to Grand Teton National Park, which preserves the most scenic section of the Teton range.

The Continental Divide spans north-south across the central portion of the state. Rivers east of the Divide drain into the Missouri River Basin and eventually the Atlantic Ocean. They are the Platte, Wind, Big Horn and the Yellowstone rivers. The Snake River in northwest Wyoming eventually drains into the Columbia River and the Pacific Ocean, as does the Green River through the Colorado River Basin.

The Continental Divide forks in the south central part of the state in an area known as the Great Divide Basin where the waters that flow or precipitate into this area remain there and cannot flow to any ocean. Instead, because of the overall aridity of Wyoming, water in the Great Divide Basin simply sinks into the soil or evaporates.

Several rivers begin or flow through the state, including the Yellowstone River, Powder River, Green River, and the Snake River.

Public Lands

Over 48% of the land in Wyoming is owned by the U.S. Government, which ranks fifth in the US in both total acres owned by the Federal Government and by percentage of a state's land owned by the Federal government.[4] This amounts to about 30,099,430 acres owned and managed by the U.S. Government. The state government owns an additional 6% of all Wyoming lands, or another 3,864,800 acres.[5]

The vast majority of this government land is managed by the Bureau of Land Management and U.S. Forest Service in numerous National Forests, a National Grassland, and a number of vast swaths of public land.

In addition, Wyoming contains a number of specific areas that are under the management of the National Park Service and other agencies. They include:

Parks

Recreation Areas

National Monuments

National Historic Trails and Sites

National Parkways

Wildlife Refuges and Hatcheries


Climate

Wyoming state welcome sign

The climate in Wyoming is generally a semi-arid continental climate (Koppen climate classification BSk) which is drier and windier in comparison to most of the United States with 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 °F (29°C) and 95 °F (35°C) in most of the state. With increasing elevation, however, this average drops rapidly with locations above 9,000 feet (2,743 m) averaging around 70 °F (21°C). Summer nights throughout the state are characterized by a rapid cooldown with even the hottest locations averaging in the 50-60 °F (10-14°C) range at night. In most of the state, the late spring and early summer is when most of the precipitation tends to fall. 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 an arid state with much of the land receiving less than 10 inches (25 cm) of rainfall per year. Precipitation depends on elevation with lower areas in the Big Horn Basin averaging 5-8 inches (125 - 200 mm) (making the area nearly a true desert). The lower areas in the North and on the eastern plains typically average around 10-12 inches (250-300 mm), making the climate there semi-arid. Some mountain areas do receive a good amount of precipitation, 20 inches (510 mm) or more, much of it as snow, sometimes 200 inches (510 cm) or more annually.

The climate of any area in Wyoming is largely determined by its latitude, altitude and local topography. When put together, these factors have a lot to do with airflow patterns, temperature variations, precipitation and humidity brought in by the weather systems that migrate eastward. In winter, Wyoming is often beneath the jet stream, or north of it, which accounts for its frequent strong winds, blasts of Arctic air and precipitation, all the necessary ingredients for great snow conditions at Wyoming's northwestern ski areas. In summer, the jet stream retreats northward to somewhere over Canada, leaving the state's weather mild and pleasant at a time when the majority of Wyoming's visitors choose to arrive. Jackson, located at 6,230 feet (1,899 m) above sea level and surrounded by mountains, can expect a high temperature in July of 80˚ F (26.6°C). The average is more likely to be 65˚ F (18.3°C). The closest National Weather Station (in Riverton on the other side of the Wind River Mountains at 4,955 feet (1,510 m)) reports slightly warmer July weather.

Weather and topography in Wyoming both have more contrast than in most other states. Severe weather is not uncommon in Wyoming, with the state being one of the leading states for hail damage in the United States. 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 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 which occur a little further east.

History

Several Native American groups originally inhabited the region we know as Wyoming. The Crow, Arapaho, Lakota, and Shoshone were but a few of the original inhabitants encountered when white explorers first entered the region. Although French trappers may have ventured into the northern sections of the state in the late 1700s, John Colter, a member of the Lewis and Clark Expedition, first described the region in 1807. His reports of the Yellowstone area were considered at the time to be fictional. Robert Stuart and a party of five men returning from Astoria discovered South Pass in 1812. The Oregon Trail later followed that route. In 1850, Jim Bridger located what is now known as Bridger Pass, which the Union Pacific Railroad used in 1868 — as did Interstate 80, ninety years later. Bridger also explored Yellowstone and filed reports on the region that, like those of Colter, were largely regarded as tall tales at the time.

The region may have acquired the name Wyoming as early as 1865, when Representative J. M. Ashley of Ohio introduced a bill to Congress to provide a "temporary government for the territory of Wyoming." The name Wyoming derives from the Delaware (Munsee) name xwé:wamənk, meaning "at the big river flat," originally applied to the Wyoming Valley in Pennsylvania, made famous by the 1809 poem Gertrude of Wyoming by Thomas Campbell.[6][7]

After the Union Pacific Railroad reached the town of Cheyenne in 1867, the region's population began to grow steadily, and the Federal government established the Wyoming Territory on July 25, 1868.[8] Unlike Colorado to the south, Wyoming enjoyed no significant discovery of such celebrated minerals as gold and silver — nor Colorado's consequent boom in population — although some areas of Wyoming produced copper.

Once government sponsored expeditions to the Yellowstone country were undertaken, the previous reports by men like Colter and Bridger were found to be true. This led to the creation of Yellowstone National Park, which became the world's first National Park in 1872. Nearly all of Yellowstone National Park lies within the far northwestern borders of Wyoming.

In 1869, Wyoming extended much suffrage to women, at least partially in an attempt to garner the votes to be admitted as a state. In addition to being the first U.S. state to extend suffrage to women, Wyoming was also the home of many other firsts for U.S. women in politics. For the first time, women served on a jury in Wyoming (Laramie in 1870). Wyoming had the first female court bailiff (Mary Atkinson, Laramie, in 1870) and the first female justice of the peace in the country (Esther Hobart Morris, South Pass City, in 1870). Wyoming became the first state in the Union to elect a female governor, Nellie Tayloe Ross, who was elected in 1924 and took office in January 1925.

The United States admitted Wyoming into 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 federal 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.

Population

The center of population of Wyoming is located in Natrona County. [2]

As of 2005, Wyoming has an estimated population of 509,294, which is an increase of 3,407, or 0.7%, from the prior year and an increase of 15,512, or 3.1%, since the 2000 census. This includes a natural increase since the last census of 12,165 people (that is 33,704 births minus 21,539 deaths) and an increase from net migration of 4,035 people into the state. Immigration from outside the United States resulted in a net increase of 2,264 people, and migration within the country produced a net increase of 1,771 people. In 2004, the foreign-born population was 11,000 (2.2%). In 2005, total births in Wyoming numbered 7,231 (Birth Rate of 14.04). [3]

Sparsely populated, Wyoming is the least populous state of the United States (including the District of Columbia), and has the second lowest population density, behind Alaska.

Economy

According to the 2005 U.S. Bureau of Economic Analysis report, Wyoming’s gross state product was $27.4 billion. Wyoming’s unemployment rate for 2006 was approximately 3.3%, which is lower than the national average of 4.6%. Components of Wyoming's economy differ significantly from those of other states. The mineral extraction industry and the travel and tourism sector are the main drivers behind Wyoming’s economy. The Federal government owns about 50% of its landmass, while 6% is controlled by the state. Total taxable values of mining production in Wyoming for 2001 was over $6.7 billion. The tourism industry accounts for over $2 billion in revenue for the state.

In 2002, over six million people visited Wyoming’s national parks and monuments. The key tourist attractions in Wyoming include Grand Teton National Park, Yellowstone National Park, Devils Tower National Monument and Fossil Butte National Monument. Each year Yellowstone National Park receives three million visitors.

Historically, agriculture has been an important component of Wyoming’s economic identity. Its overall importance to the performance of Wyoming’s economy has waned. However, it is still an essential part of Wyoming’s culture and lifestyle. The main agricultural commodities produced in Wyoming include livestock (beef), hay, sugar beets, grain (wheat and barley), and wool. Over 91% of land in Wyoming is classified as rural.
