Wyoming is the 10th most extensive, but the least populous and the 2nd least densely populated of the 50 United States. The western two thirds of the state is covered mostly with the mountain ranges and rangelands in the foothills of the Eastern Rocky Mountains, while the eastern third of the state is high elevation prairie known as the High Plains.
The mountain ranges below are listed by name, county, coordinates, and average elevation as recorded by the U.S. Geological Survey. Sub-ranges are indented below the name of the primary range. Some of these ranges extend into Colorado, Montana, Idaho, and Utah.
