About this map

The Bear Mountains dominate this 1962 survey of Calaveras County, where the landscape is defined by the industrial legacy of the Mother Lode region. Mining activity is prominent throughout the terrain, particularly in the southern reaches where the Mountain King Mine, Royal Mine, and Big Seven Mine are located near Gopher Ridge. The rugged topography, characterized by deep cuts like Heiser Canyon and peaks like Mount Ararat, drops off into the broad floor of Salt Spring Valley.

The western edge of the quadrangle is marked by the Salt Spring Valley Reservoir, which serves as a central hydrological feature for local ranching operations. Significant family-named landmarks and small settlements such as Red House Ranch, Carmen City, and Pools Station provide specific coordinates for genealogical research. These scattered outposts, connected by a network of unimproved roads and trails, reflect the rural and extractive character of this portion of the foothills in the early 1960s.
