Edge of Plains

Grassy plains meet pine-dotted uplands as these lands transition from the Great Plains to the Basin and Range Province, a geographic region covering much of the western United States and northwestern Mexico. To the east, caliche, sand, and gravel cap the plains, which are deeply eroded in places to the underlying bedrock. To the west, faulting has produced alternating highlands and intermountain basins. The elevation here is 6,500 feet above sea level.
