Orocopia Mountains Wilderness Area

Location of the Orocopia Mountains

The area is the Bureau of Land Management (BLM) designated and managed Orocopia Mountains Wilderness Area.[2] The Orocopia Mountains are in the Colorado Desert section of the Sonoran Desert, adjacent to the Lower Colorado River Valley region. Just to the north is the Mecca Hills Wilderness Area.

Flora and fauna

The Wilderness Area includes some remnant natural spring fed oasis with the only California native palm, Washingtonia filifera or the California Fan Palm.

History

The Bradshaw Trail passed through the mountains, the first "euroamerican" route to the Colorado River from Riverside, California.

Geology and astronauts

The dramatic and variable terrain was shaped primarily by movements of the adjacent San Andreas Fault over millennia.

The Orocopia Mountains offer considerable geologic variety and was one of the areas used for geologic field training by Caltech Professor of Geology, Leon T. Silver, for astronauts in preparation for the NASA Apollo Moon landing missions.[3]
