This is a dry-placer mining district in western San Bernardino County about 15 miles northwest of Barstow. The area was mined intermittently from around 1900 to 1915, with a total output valued at about $100,000. The principal operator was the Cool Gardie Mining Company, which operated a battery of gasoline-powered dry washers. Several two-man operations employed single dry washers or rockers (see photo 77). Minor prospecting was done in the district during the 1920s and 1930s. The deposits are in a broad valley; the gold apparently was derived from veins in granitic rocks that are to the east and northeast.
