Wyoming

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 {{lang|umu|xwé:wamənk}} ("at the big river flat").Bright, William (2004). Native American Place Names of the United States.

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.{{Cite web |title=The Fur Trade in Wyoming {{!}} WyoHistory.org |url=https://www.wyohistory.org/encyclopedia/fur-trade-wyoming |access-date=2024-01-05 |website=www.wyohistory.org}}

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.{{Gutenberg |no=42112 |name=The Yellowstone National Park |bullet=none }} 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.{{Cite web |title=A Map of the West in his Head: Jim Bridger, Guide to Plains and Mountains {{!}} WyoHistory.org |url=https://www.wyohistory.org/encyclopedia/jim-bridger |access-date=2024-01-05 |website=www.wyohistory.org}} 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.{{Cite web |date=2016-02-06 |title=Jim Bridger: The man, the myth, the legend |url=https://www.seattletimes.com/nation-world/jim-bridger-the-man-the-myth-the-legend/ |access-date=2024-01-05 |website=The Seattle Times |language=en-US}}

After the Union Pacific Railroad reached Cheyenne in 1867, population growth was stimulated. The federal government established the Wyoming Territory on July 25, 1868.[http://wyoming.gov/state/wyoming_news/general/history.asp State of Wyoming—General Facts About Wyoming] {{webarchive |url=https://web.archive.org/web/20070927200649/http://wyoming.gov/state/wyoming_news/general/history.asp |date=September 27, 2007 }} 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.{{cite web |url=http://wyoparks.state.wy.us/Site/Brochure/SouthPassCity.pdf |title=South Pass City Historic Site |publisher=Wyoming State Parks, Historic Sites & Trails |url-status=dead |archive-url=https://web.archive.org/web/20090227040747/http://wyoparks.state.wy.us/Site/Brochure/SouthPassCity.pdf |archive-date=February 27, 2009 |df=mdy-all }} Copper was mined in some areas between the Sierra Madre Mountains and the Snowy Range near Grand Encampment.{{cite book |url=https://books.google.com/books?id=M8pIAAAAMAAJ |title=Mines Register: Successor to the Mines Handbook and the Copper Handbook, Describing the Non-ferrous Metal Mining Companies in the Western Hemisphere |year=1911 |last1=Stevens |first1=Horace Jared |last2=Weed |first2=Walter Harvey |last3=Neale |first3=Walter Garfield |last4=Rand |first4=Lenox Hawes |last5=Sturgis |first5=Edward Barney |last6=Zimmerman |first6=Joseph |display-authors=2}}

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.{{cite web |title=Women's History Collections |url=https://www.uwyo.edu/ahc/collections/by-subject/women.html |accessdate=April 14, 2023 |publisher=American Heritage Center}} Women first served on juries in Wyoming (Laramie in 1870). Wyoming was also a pioneer in welcoming women into electoral politics.{{cite web|last=Helton|first=Jennifer|url=https://www.smithsonianmag.com/history/how-american-west-led-way-women-politics-180975573/|title=How the American West Led the Way for Women in Politics|work=Smithsonian|date=August 14, 2020|accessdate=April 14, 2023}} It 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). In 1924, Wyoming was the first state to elect a female governor, Nellie Tayloe Ross, who took office in January 1925.{{cite book |last=Larson |first=T. A. |title=History of Wyoming |url=https://books.google.com/books?id=9zVKYtdsUDEC |year=1990 |publisher=University of Nebraska Press |isbn=978-0-803-27936-0}} 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.{{cite book |title=Frontier Spirit: The Story of Wyoming |last=Sodaro |first=Craig |author2=Adams, Randy |year=1996 |publisher=Johnson Books |isbn=978-1-55566-163-2 |pages=136–39}} 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.

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.

File:Autumn in the Bighorn Mountains.JPG

Wyoming's climate is generally semi-arid and continental (Köppen climate classification BSk) and is drier and windier in comparison to most of the United States with greater temperature extremes.{{cite web|url=http://www.wrds.uwyo.edu/sco/wyoclimate.html|title=The Climate of Wyoming|publisher=Wyoming State Climate Office and Water Resources Data System|accessdate=April 14, 2023}}{{cite web|url=https://www.nps.gov/fola/planyourvisit/weather.htm?fullweb=1|title=Weather|publisher=U.S. National Park Service|accessdate=April 14, 2023}} Much of this is due to the topography of the state. Summers in Wyoming are warm with July high temperatures averaging between {{convert|80|and|90|°F|°C|abbr=on}} in most of the state. With increasing elevation, however, this average drops rapidly with locations above {{convert|9000|ft|m}} averaging around {{convert|70|°F|°C|abbr=on}}. Summer nights throughout the state are characterized by a rapid cooldown with even the hottest locations averaging in the {{convert|50|–|60|F|C}} 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 {{convert|10|in|mm}} of rainfall per year. Precipitation depends on elevation with lower areas in the Big Horn Basin averaging {{convert|5|-|8|in|mm}}, making the area nearly a true desert. The lower areas in the North and on the eastern plains typically average around {{convert|10|-|12|in|mm}}, making the climate there semi-arid. Some mountain areas do receive a good amount of precipitation, {{convert|20|in|mm}} or more, much of it as snow, sometimes {{convert|200|in|cm}} or more annually. The state's highest recorded temperature is {{convert|114|F|C}} at Basin on July 12, 1900, and the lowest recorded temperature is {{convert|-66|F|C}} 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.

As specified in the designating legislation for the Territory of Wyoming, Wyoming's borders are lines of latitude 41°N and 45°N, and longitude 104°3'W and 111°3'W (27 and 34 west of the Washington Meridian)—a geodesic quadrangle.{{cite web|author=Willam J.

It is the tenth largest state in the United States in total area, containing {{convert|97814|sqmi|km2}} and is made up of 23 counties.

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 {{convert|13804|ft|m}}, to the Belle Fourche River valley in the state's northeast corner, at {{convert|3125|ft|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 both in geology and in 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 {{convert|13000|ft|m|abbr=on}} tall in addition to Gannett Peak, the highest peak in the state. The Bighorn Mountains in the north-central portion are somewhat isolated from the bulk of the Rocky Mountains.

The Teton Range in the northwest extends for {{convert|50|mi|km}}, part of which is included in Grand Teton National Park. The park includes the Grand Teton, the second-highest peak in the state.

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 Gulf of Mexico. They are the North Platte, Wind, Bighorn, and 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 water that precipitates onto or flows into it cannot reach an ocean—it all sinks into the soil and eventually evaporates.

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

Much of Wyoming is covered with large basins containing different eco-regions, from shrublands to smaller patches of desert.{{cite web|url=http://www.landscope.org/explore/natural_geographies/ecoregions/Wyoming%20Basins/|publisher=Landscope|date=June 26, 2012|access-date=March 11, 2021|archive-url=https://web.archive.org/web/20200226072841/http://www.landscope.org/explore/natural_geographies/ecoregions/Wyoming%20Basins/|archive-date=February 26, 2020|url-status=live| title= Wyoming Basins Ecoregion }} Regions of the state classified as basins contain everything from large geologic formations to sand dunes and vast unpopulated spaces.{{cite web|url=https://hort.purdue.edu/newcrop/cropmap/ecoreg/descript.html#18|website=hort.purdue.edu|publisher=Purdue University|date=April 1, 2000|access-date=March 9, 2021|archive-url=https://web.archive.org/web/20210211032359/https://hort.purdue.edu/newcrop/cropmap/ecoreg/descript.html|archive-date=February 11, 2021|url-status=live| title=Level III Ecoregions of the Continental United States}} Basin landscapes are typically at lower elevations and include rolling hills, valleys, mesas, terraces and other rugged terrain, but also include natural springs as well as rivers and artificial reservoirs.{{cite web|url=ftp://newftp.epa.gov/EPADataCommons/ORD/Ecoregions/wy/wy_front.pdf|publisher=EPA|date=Jan 1, 2004|access-date=March 9, 2021|title=Wyoming Eco-Regions|archive-date=May 9, 2022|archive-url=https://web.archive.org/web/20220509200704/ftp://newftp.epa.gov/EPADataCommons/ORD/Ecoregions/wy/wy_front.pdf|url-status=live}} They have common plant species such as various subspecies of sagebrush, juniper and grasses such as wheatgrass, but basins are known for their diversity of plant and animal species.

Wyoming experienced its first population decline since 1990, with a decrease of just over 1,000 people (0.2 percent) from July 2015 to July 2016. This decline was attributed to the downturn in the state's mineral extraction industry, particularly the oil and gas sector, which led to the loss of thousands of jobs. However, state economist Jim Robinson noted signs of economic stabilization. Job losses in the oil and gas industry appeared to have leveled off, and there was a slight increase in drilling activity in recent months. While the state's economy showed little growth, it was considered to have reached a more stable condition as of late 2016.{{Cite web |last=AP |date=2016-12-22 |title=Wyoming population drops, but there are positive signs in economy |url=https://www.wyomingnewsnow.tv/news/state/wyoming-population-drops-but-there-are-positive-signs-in-economy/article_d37ca7a2-da00-56fb-be25-9e4a1e45c291.html |access-date=2025-03-09 |website=Wyoming News Now |language=en}}

In 2018, tourism industry contributed approximately $3.8 billion in spending from domestic and international visitors.

In 2002, more than six million people visited Wyoming's national parks and monuments. Wyoming's main tourist attractions include Grand Teton National Park, Yellowstone National Park, Devils Tower National Monument, Independence Rock and Fossil Butte National Monument. Yellowstone, established in 1872 as the world's first national park, attracts over three million visitors each year.

Historically, agriculture has been an important component of Wyoming's economy. Its overall importance to the economy has waned, but it is still an essential part of Wyoming's culture and lifestyle. The main agricultural commodities Wyoming produces include livestock (beef), hay, sugar beets, grain (wheat and barley), and wool. More than 91% of Wyoming's land is classified as rural.

Wyoming is the home of only a handful of companies with a regional or national presence. Taco John's and Sierra Trading Post, both in Cheyenne, are privately held. Cloud Peak Energy in Gillette and U.S. Energy Corp. (NASDAQ: USEG) in Riverton are Wyoming's only publicly traded companies.

The state collects a use tax of 5% on items purchased elsewhere and brought into Wyoming. All property tax is based on the property's assessed value; Wyoming's Department of Revenue's Ad Valorem Tax Division supports, trains, and guides local government agencies in the uniform assessment, valuation and taxation of locally assessed property. "Assessed value" means taxable value; "taxable value" means a percentage of the fair market value of property in a particular class. Statutes limit property tax increases. For county revenue, the property tax rate cannot exceed 12 mills (or 1.2%) of assessed value. For cities and towns, the rate is limited to eight mills (0.8%). With very few exceptions, state law limits the property tax rate for all governmental purposes.

Personal property held for personal use is tax-exempt. Inventory held for resale, pollution control equipment, cash, accounts receivable, stocks and bonds are also exempt. Other exemptions include property used for religious, educational, charitable, fraternal, benevolent and government purposes and improvements for handicapped access. Mine lands, underground mining equipment, and oil and gas extraction equipment are exempt from property tax, but companies must pay a gross products tax on minerals and a severance tax on mineral production.{{cite web |url=http://www.wvpolicy.org/getting-the-story-right-mineral-taxation-in-wyoming-and-west-virginia |archive-url=https://web.archive.org/web/20130117043021/http://www.wvpolicy.org/getting-the-story-right-mineral-taxation-in-wyoming-and-west-virginia |url-status=dead |archive-date=January 17, 2013 |title=Getting the Story Right; Mineral Taxation in Wyoming and West Virginia |publisher=West Virginia Center on Budget and Policy Blog |access-date=November 10, 2012 }}Wyoming Statutes Section 39-13-103

The Wyoming state highway system also serves the state.

Interstate 25 enters Wyoming south of Cheyenne and runs north, intersecting Interstate 80 immediately west of Cheyenne. It passes through Casper and ends at Interstate 90, near Buffalo. Interstate 80 crosses the Utah border west of Evanston and runs east through the southern third of the state, passing through Cheyenne before entering Nebraska near Pine Bluffs. Interstate 90 comes into Wyoming near Parkman and cuts through the northeastern part of the state. It serves Gillette and enters South Dakota east of Sundance.

U.S. Routes 14, 16, and the eastern section of U.S. 20 have their western terminus at the eastern entrance to Yellowstone National Park and pass through Cody. U.S. 14 runs eastward before joining I-90 at Gillette. U.S. 14 then follows I-90 to the South Dakota border. U.S. 16 and 20 split off of U.S. 14 at Greybull and U.S. 16 turns east at Worland while U.S. 20 continues south Shoshoni. U.S. Route 287 runs from Fort Collins, Colorado, to Laramie, Wyoming, through a pass between the Laramie Mountains and the Medicine Bow Mountains, then merges with US 30 and I-80 until it reaches Rawlins, where it continues north, passing Lander. Outside of Moran, U.S. 287 is part of a large interchange with U.S. Highways 26, 191, and 89, before continuing north to Yellowstone's southern entrance. U.S. 287 continues north of Yellowstone, but the park separates the two sections.

Other U.S. highways that pass through Wyoming are 18, 26, 30, 85, 87, 89, 189, 191, 212, and 287.

The State Board of Education, a nine-member board appointed by the governor, sets educational policy. The constitution prohibits the state from establishing curriculum and textbook selections; these are the prerogative of local school boards.

{{Further|Wyoming Constitution|Elections in Wyoming}}

File:Wyoming State Capitol.jpg

Wyoming's Constitution established three branches of government: the executive, legislative, and judicial branches. The state legislature comprises a House of Representatives with 60 members and a Senate with 30 members. The executive branch is headed by the governor and includes a secretary of state, auditor, treasurer, and superintendent of public instruction. As Wyoming does not have a lieutenant governor, the secretary of state is first in the line of succession.

Wyoming's sparse population warrants the state only one at-large seat in the U.S. House of Representatives, and hence only three votes in the Electoral College.

The Wyoming State Liquor Association is the state's sole legal wholesale distributor of spirits, making it an alcoholic beverage control state. With the exception of wine, state law prohibits the purchase of alcoholic beverages for resale from any other source.{{cite web|url=http://wyoliquor.org/html/common_questions.htm |title=Common Questions |publisher=Wyoming State Liquor Association |access-date=18 Feb 2014 |url-status=dead |archive-url=https://web.archive.org/web/20140212185550/http://wyoliquor.org/html/common_questions.htm |archive-date=February 12, 2014}}

Wyoming's highest court is the Supreme Court of Wyoming, with five justices presiding over appeals from the state's lower courts. Wyoming is unusual in that it does not have an intermediate appellate court, like most states. This is largely attributable to the state's population and correspondingly lower caseload. Appeals from the state district courts go directly to the Wyoming Supreme Court. Wyoming also has state circuit courts (formerly county courts), of limited jurisdiction, which handle certain types of cases, such as civil claims with lower dollar amounts, misdemeanor criminal offenses, and felony arraignments. Circuit court judges also commonly hear small claims cases as well.

Before 1972, Wyoming judges were selected by popular vote on a nonpartisan ballot. This earlier system was criticized by the state bar which called for the adoption of the Missouri Plan, a system designed to balance judiciary independence with judiciary accountability. In 1972, an amendment to Article{{nbsp}}5 of the Wyoming Constitution, which incorporated a modified version of the plan, was adopted by the voters. Since the adoption of the amendment, all state court judges in Wyoming are nominated by the Judicial Nominating Commission and appointed by the Governor. They are then subject to a retention vote by the electorate one year after appointment.{{cite book |last1=Hubble |first1=Larry |title=The Equality State: Government and Politics in Wyoming |date=2008 |publisher=Eddie Bowers Publishing Co. |location=Peosta, Iowa |isbn=978-1-57879-076-0 |pages=91–92 |edition=6th|display-authors=etal}}

Wyoming's political history defies easy classification. The state was the first to grant women the right to vote and to elect a woman governor.{{cite web |url=http://memory.loc.gov/ammem/today/dec10.html |title=Today in History |publisher=The Library of Congress |access-date=July 20, 2012 |archive-url=https://web.archive.org/web/20120608171436/http://memory.loc.gov/ammem/today/dec10.html |archive-date=June 8, 2012 |url-status=live }} On December 10, 1869, John Allen Campbell, the first Governor of the Wyoming Territory, approved the first law in United States history explicitly granting women the right to vote. This day was later commemorated as Wyoming Day. On November 5, 1889, voters approved the first constitution in the world granting full voting rights to women.

While the state elected notable Democrats to federal office in the 1960s and 1970s, politics have become decidedly more conservative since the 1980s as the Republican Party came to dominate the state's congressional delegation. Today, Wyoming is represented in Washington by its two Senators, John Barrasso and Cynthia Lummis, and its one member of the House of Representatives, Congresswoman Harriet Hageman. All three are Republicans; a Democrat has not represented Wyoming in the Senate since 1977 or in the House since 1978. The state has not voted for a Democrat for president since 1964, one of only eight times since statehood. In the 2004 presidential election, George W. Bush won his second-largest victory, with 69% of the vote. Former Vice President Dick Cheney is a Wyoming resident and represented the state in Congress from 1979 to 1989.

The last time a Democrat won a statewide election in Wyoming was in 2006, when Democratic governor Dave Freudenthal was re-elected to a second term by a wide margin, winning every county in the state. For 19 of Wyoming's 23 counties, 2006 marked the last time that they voted for the Democratic nominee in a statewide race. Of the remaining 4, Sweetwater County last voted Democratic in the 2008 U.S. House race and Laramie County last voted Democratic in the 2014 Superintendent of Public Instruction race, leaving Teton and Albany as the only counties that Democrats are able to win. Teton, which is composed of affluent resort communities, is reliably Democratic, except in Republican landslides like the 2022 gubernatorial election; Albany, which contains the college town of Laramie, is more competitive.

Republicans are dominant at the state level. They have held a majority in the state senate continuously since 1936 and in the state house since 1964, though Democrats held the governorship for all but eight years between 1975 and 2011. Uniquely, Wyoming elected Democrat Nellie Tayloe Ross as the first woman in United States history to serve as state governor. She served from 1925 to 1927, winning a special election after her husband, William Bradford Ross, unexpectedly died a little more than a year into his term.{{cite book |author=Teva J.

Due to its sparse population, Wyoming lacks any major professional sports teams; the Gillette Mustangs, an indoor football team based in Gillette that began play in 2021 prior to their departure from the city in 2023, were previously the only professional team in the state. However, the Wyoming Cowboys and Cowgirls—particularly the football and basketball teams—are quite popular; their stadiums in Laramie are about {{convert|7,200|ft|m}} above sea level, the highest in NCAA Division{{nbsp}}I. The Wyoming High School Activities Association also sponsors twelve sports and there are three junior ice hockey teams, all of which are members of the NA3HL. Casper has hosted the College National Finals Rodeo since 2001.
