Location and History
The Chuckwalla district is in the Chuckwalla Mountains of southeastern Riverside County, south of Desert Center. This district at one time was also known as the Pacific mining district. It was organized some time in the 1880s, and mining continued through the early 1900s. There was activity here again in the 1930s, when the Red Cloud and other mines were worked.
Geology and Ore Deposits
The region is underlain by granitic rocks and gneiss. The gold-quartz veins often contain abundant pyrite and copper, lead, and silver minerals. A number of high-grade pockets have been recovered. Several of the veins have mined to depths of about 350 feet.
