Boulder transported by debris flow, Marble Canyon, Death Valley National Park, Inyo County, California

A large granite boulder blocks the stream channel in Marble Canyon in the Cottonwood Mountains in Death Valley National Park (Inyo County). The boulder is roughly 10 feet (3 meters) in diameter. The closest bedrock occurrence of similar granite is nearly 8 miles (12 km) away in the central Cottonwood Mountains. The boulder moved to its present location possibly entrained in a massive debris flood or debris flow in prehistoric times.
