Wyoming and the world 7
The state of Wyoming is located in the central part of the North American continent, bounded between 104 and 111 degrees west longitude and 41 and 45 degrees north latitude.
Wyoming straddles the Continental Divide and the Rocky Mountains, with the Great Plains to the east and the Intermountain Basin region to the west. Wyoming shares a border with six surrounding states.

Elevation
The highest point in Wyoming is Gannett Peak at 13,809 feet (4,209 meters), in the Wind River Range. There are more than 40 other named peaks taller than 13,000 feet in the Wind River Range, including many near Titcomb Basin, pictured below.
The eastern part of Wyoming is dominated by high plains. The middle and western parts of the state have several distinct ranges of the Rocky Mountains, divided by large basins. Even the basins have relatively high elevations, averaging 6,200 feet (1,890 meters). Wyoming’s basins include many remarkable natural features such as the Killpecker Sand Dunes, one of the largest active dune systems in North America.

The lowest point in the state is where the Belle Fourche River flows out of Wyoming into South Dakota, at 3,099 feet (945 meters).

Native American tribes 24
The arrival of the Spanish in the 1500s brought the domesticated horse into North America. By the 1700s, the horse became an integral part of some Native American cultures and allowed them to migrate deeper into the Great Plains, expand their hunting ranges, and to focus their hunting on bison. Before the arrival of Europeans the dominant Native American groups inhabiting Wyoming were the Shoshone, Crow, Cheyenne, and Arapaho. The Sioux Nation joined this list in the 1830s when they were invited to trade at Fort William (later Fort Laramie).
By the mid-1800s, established emigration routes like the Oregon and Bozeman trails brought increasing numbers of European Americans to settle in Wyoming. As a result, hostilities between the local tribes and settlers often escalated into open disputes where the Sioux, Cheyenne, and Arapaho defended their territories. These disputes led to a number of treaties between the Native Americans and the U.S. government to protect European settlers on what had been tribal lands.
Initially the Fort Laramie Treaty (1868) promised the Cheyenne, Crow, Arapaho, and Sioux all lands of the Powder River area and the Black Hills. The Shoshone were allotted the lands in the Wind River Valley by the Fort Bridger Treaty of 1868. By 1877, the U.S. government had seized the lands of northeastern Wyoming from the Sioux and the Crow, and relocated the Arapaho to the Wind River Reservation (1878) to live with the Shoshone, their traditional enemy.
Today, many Shoshone and Arapaho live on the Wind River Reservation in central Wyoming; the Crow and Northern Cheyenne are on reservations in southeastern Montana; and the Sioux Nation is split between reservations in South Dakota, North Dakota, and Nebraska.

Population change 29
Wyoming has a population density of fewer than six people per square mile. Conversely, New Jersey, the U.S.’s most densely populated state, has 1,205 people per square mile. At that density, the entire country’s population could be packed into an area equaling the combined size of Wyoming and Montana.
Sublette and Campbell counties have both experienced rapid growth in recent years due to the presence of oil, gas and coal extraction. From 2000 to 2010, Sublette saw a 73 percent increase, while Campbell grew by 37 percent.

Wyoming ranks fifth in the nation in the production of natural gas. Recent advancement in drilling technology may mean significant numbers of new wells in Wyoming’s Green River and Wind River basins, in addition to the large Pinedale Anticline (pictured) and Jonah fields. Coalbed natural gas production in the Powder River Basin has declined since 2009 after a decade-long boom.
The first oil well drilled in Wyoming was at Dallas Dome in 1883, followed by Salt Creek. Salt Creek is the most productive field in Wyoming’s history, producing over 696 million barrels since 1889. Wyoming’s oil boom peaked in 1970, but production has been increasing again since 2009, in part due to enhanced oil recovery. Wyoming ranks ninth in production of crude oil in the nation.
Total production in millions of barrels 1978–2013. Production is mapped by “fields,” areas which have a high density of wells.

Wyoming’s Western heritage 45
Cheyenne Frontier DaysNicknamed the “Daddy of ‘em All,” Cheyenne Frontier Days has been a staple of Wyoming rodeo culture since its inception in 1897. The Frontier Days Rodeo is one of the biggest events on the professional rodeo circuit, attracting some of the world’s best competitors.
Guest ranches (2014)Guest ranches allow tourists to experience the bygone days of the “Old West” and rural lifestyle aspects of Wyoming. Guest ranches vary in accommodations and to whom they cater, ranging from working cattle ranches to upscale resorts or spas.
Buffalo Bill Historical CenterThis complex of five museums is named after Buffalo Bill Cody (1846–1917), who gained fame with his “Wild West Show,” a theatrical embellishment of the mythic Wild West.
