About this map

The gold-bearing quartz veins of California's Mother Lode dominate this 1947 field-checked study, centering on the historic mining hub of Coulterville. This landscape is densely populated with hard-rock mining sites such as the Mary Harrison Mine, Virginia Mine, and the Mountain King Mine along the Merced River. The map illustrates the transition from the rugged mining camps of the mid-19th century toward more established agricultural and civic life, evidenced by the Greeley Hill School and Quartzburg School.

Downstream, the early stages of Lake McClure and the riverside settlement at Bagby reflect the region's reliance on water power and transportation. Notable landmarks like Fremont Peak and the Bullion Mountains rise over significant historical outposts including Bear Valley, Hornitos, and Mount Bullion. These areas, marked by numerous small pits and family-named mines like the My Gaines Mine, provide a detailed record of the mining activity that shaped Mariposa County.
