California Historic Gold Mining Locations

California has produced more gold than any other State - more than 106 million ounces from 1848 through 1965. The well-known discovery in El Dorado County in 1848 sparked a series of gold rushes that indirectly led to colonization of the entire mountain West. The rich gold placers of California yielded phenomenal wealth in the early years, and as the placers were depleted, prospectors searched for and found the source of the placer gold - the high-grade gold-quartz veins of the Mother Lode and Grass Valley. Others explored the forbidding mountain ranges of southern California and found productive lodes in the Cove, Rand, and Stedman districts. Placer mining was rejuvenated in the early 1900's with the introduction of large bucket dredges. From the late 1930's onward, dredging operations were responsible for a major part of California's gold output*. Gold Prospecting Research Material for California
