Clipper Valley is a vast, oval-shaped alluvial plain located in the eastern Mojave Desert, in San Bernardino County, California, in the south of the Mojave National Preserve.
Interstate 40 passes the valley along its southern border, and Needles, California and the Colorado River are to the east.
Covering over 400 square miles (1,000 km2), the valley is large enough to hold most of greater Los Angeles.
The valley was part of the homeland of the Mojave people for thousands of years.
The region has been the site of numerous mining operations, particularly during the 1840s Gold Rush.
