The Pacific Coast region includes most of California and the western portions of Oregon and Washington (>Fig.I.1b). Exploration in the 1950s led to the discovery of a number of minor uranium deposits and occurrences mainly of surficial type, but of no major deposit to date. Most discoveries were made from 1954 to 1959 in southeastern and eastern California, namely in the Mojave Desert near Big Bear Lake, San Bernardino County, the McCoy Mountains in Riverside County, the Kern River Canyon area in Kern County, the Coso Range in Inyo County, the Sonora Pass area in Tuolumne County, and the Petersen Mountain area in Lassen County. A total of about 30 t U has been intermittently produced from 1954 to 1968 from a number of small deposits in these areas. About 60% of this total came from the Juniper Mine in the Sonora Pass area making it the largest single uranium producer in California.
