Wyoming map

Where Wyoming is

Wyoming is the rectangle of the Mountain West between the 41st and 45th parallels, about 365 miles east to west and 275 miles north to south. Clockwise from the north: Montana along the 45th parallel, South Dakota and Nebraska along a meridian to the east, Colorado and Utah along the 41st parallel to the south, and Utah and Idaho along a meridian to the west. It is the tenth-largest state by area and the least populous, with fewer people than Milwaukee.

Major cities

Cheyenne and Casper are the only cities above 50,000. Jackson, the gateway to Grand Teton and Yellowstone, has about 10,000 residents.

Geography

• Highest point — Gannett Peak, 13,804 ft, in the Wind River Range; the Grand Teton (13,775 ft) is second. Wyoming's mean elevation of about 6,700 ft is the second highest after Colorado.
• Yellowstone — the first national park (1872) fills the northwest corner, with Grand Teton just south of it. See the Yellowstone map.
• Continental Divide — crosses the state from Yellowstone southeast through the Wind Rivers and splits around the Great Divide Basin, an area that drains to neither ocean. See the Continental Divide map.
• Rivers — the Yellowstone and Bighorn flow north to the Missouri; the North Platte crosses the southeast through Casper; the Green River in the southwest is the main headwater of the Colorado; the Snake rises in Yellowstone and leaves through Jackson Hole.
• Ranges and basins — the Bighorn Mountains, Absarokas, Wind Rivers, Tetons, Medicine Bow and Laramie ranges of the Rocky Mountains alternate with the Bighorn, Wind River, Powder River and Green River basins. The eastern third is Great Plains.
• Lowest point — about 3,099 ft on the Belle Fourche River at the South Dakota line in the northeast, near Devils Tower.

Borders

Wyoming and Colorado are the only states bounded entirely by lines of latitude and longitude. The 45th parallel (Montana), 41st parallel (Colorado and Utah), and the 27th and 34th meridians west of Washington (about 104°03'W and 111°03'W) form the rectangle set by the 1868 act creating Wyoming Territory. The territory was assembled from parts of Dakota, Utah and Idaho territories with no regard to terrain, which is why the Idaho line cuts across the Teton Range and the Montana line cuts through Yellowstone's northern edge. Survey errors give the lines small jogs, most visibly on the Utah border.

Regions of Wyoming

Southeastern Wyoming (Cheyenne, Laramie, the high plains), Central Wyoming (Casper, the North Platte valley), the Powder River Basin and Black Hills country in the northeast (Gillette, Sheridan, Devils Tower), the Bighorn Basin (Cody, Worland), Northwestern Wyoming (Yellowstone, Jackson Hole), the Wind River country (Lander, Riverton, the Wind River Reservation) and Southwestern Wyoming (Rock Springs, Green River, Evanston).
