Eastern Mojave Vegetation Shivwits Plateau, Mohave County, Arizona.

Query: G.N.I.S.

The Shivwits Plateau is a vast tableland and its western edge forms a dramatic escarpment, one of the nationšs most remarkable ecotones (ecological transition zones). Most of the Shivwits Plateau lies at elevations of 6,000­7,000 feet, with a capping veneer of basalt flows and volcanic peaks that rise above 8,000 feet. These lands encompass remarkably long cliff lines, the boundary between the Basin and Range and Colorado Plateau geologic provinces, extensive archeological features, pinyon-juniper and ponderosa pine forests, desert spring ecosystems, and desert tortoise, California condor, desert bighorn sheep, and pronghorn habitat.

Elevation: 6339ft, 1932m.
