This district is in southwestern San Bernardino County about 30 miles northeast of San Bernardino on the north side of the San Bernardino Mountains. It also has been known as the Silver Reef district. The district was organized in 1870. An English concern organized the Santa Fe group in 1890 to work the area on a large scale, but work stopped soon afterward and prospecting was minor during the early 1900s. The Santa Fe group was reopened in 1921 and operated continuously until 1940. In this last operation, the production amounted to $300,000.
The area is underlain by granitic rocks, mica schist, gneiss, and a limestone belt. A mineralized zone known as the Arlington-Santa Fe lode occurs in a thrust fault that strikes west and dips north.
