About this map

San Andreas and the Mother Lode region are captured here in the early 1990s, revealing a landscape defined by its deep mining history and complex water management systems. The map traces the historic Gold Country towns of Jackson, Sutter Creek, and Mokelumne Hill, where legacy mines dot the foothills. The terrain transitions from the low-lying Camanche reservoir area to the high-elevation ridges of the Stanislaus National Forest, including notable landmarks like Calaveras Big Trees and Indian Grinding Rock State Historical Park.

The hydrography of the region is particularly prominent, featuring the three forks of the Mokelumne River and the Stanislaus River. Significant infrastructure, including the New Hogan Lake and Pardee Reservoir, illustrates the diversion and storage of Sierra Nevada snowmelt for downstream use. Rural communities like Volcano, Wilseyville, and Valley Springs are shown connected by a winding road network that reflects the difficult topography of Bear Mountains and Table Mountain.
