This is the Wyoming state category. Wyoming's capital city is Cheyenne, and its postal abbreviation is WY. Wyoming entered the Union as the 44th state, on July 10, 1890. It is the 9th largest state, with an area of 97,818 square miles. Wyoming is located in northwestern United States. The Rocky Mountains and 10 million acres of forest dominate the landscape. The Rockies cross the state from northwest to southeast. In the east lie the rolling grasslands of the Great Plains, and the center of the state is also high plains country. The north of the state is primarily tall grass plain, where buffalo once roamed. Today, fertile farms and cattle ranches dot the land. Yellowstone National Park is the oldest and largest National Park in the USA, occupying the entire northwestern corner of Wyoming. Many rivers flow down from the mountains, including the eastward flowing North Platte and the westward flowing Snake. The USA acquired Wyoming via the Louisiana Purchase and by other treaties signed as late as 1846.
