parallel. 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 and is made up of 23 counties. From the north border to the south border it is ; and from the east to the west border is at its south end and at the north end. Natural landforms Mountain ranges 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 , to the Belle Fourche River valley in the state's northeast corner, at . 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 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 , 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
