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. The western two-thirds of the state is covered mostly by the mountain ranges and rangelands of the Rocky Mountains, while the eastern third of the state is high elevation prairie called the High Plains.
The state population was estimated at 586,107 in 2015, which is less than 31 of the most populous U. Almost half of the land in Wyoming is owned by the U. government, leading Wyoming to rank sixth by area and fifth by proportion of a state's land owned by the federal government.
