1962 Map of San Andreas

About this map

San Andreas serves as the focal point of this 1962 survey, situated at the confluence of the North Fork and South Fork Calaveras River. The landscape reveals a transition from the established gold-mining era toward modern industrial and civic development, marked by the presence of a large Cement Plant and quarries near Kentucky House. Local history is deeply etched into the terrain through numerous family-named claims such as the Cassinelli Mine and Lloyd Mine, alongside the Pioneer Cem which preserves the memory of early settlers. The mapping captures a significant hydrological shift as the Calaveras Reservoir is shown with its spillway elevation, while a dashed blue pattern indicates areas subject to controlled inundation from the New Hogan Reservoir. This document provides a clear view of the mid-century infrastructure supporting the county seat, from the Mark Twain Hospital to the Calaveras County Airport.
