Great Basin


Encompassing the entire state of Nevada, much of Utah, and parts of Idaho and Oregon, the Great Basin is a region of arid mountains in the western United States between the Rocky Mountains and Sierra Nevada Range. It consists of a series of mountain ranges in Nevada including the East Humboldt, the Ruby, and the White Mountains. The basin itself is a series of watersheds with no outlet to the sea or rivers that flow to the sea. Any precipitation that falls in the region evaporates, seeps into the ground, or, forms short-lived lakes called playas that eventually dry up.
