Intermontane basin that formed in alluvium, glacial outwash, and lacustrine sediments underlain by argillite, siltite, and dolomite. Elevations range from 2300 to 4500 feet. Drainage density is low to moderate.
Mean annual precipitation ranges from 14 to 25 inches, about 50 percent falling as snow. The soil temperature and moisture regimes are frigid and typic xeric.
