1962 Map of Keystone

About this map

Table Mountain and the Stanislaus River anchor this topographic study of the foothills where Tuolumne, Calaveras, and Stanislaus Counties converge. The landscape is defined by the massive infrastructure of the Hetch Hetchy Aqueduct carving across the center of the sheet, while the northern edge is dominated by Tulloch Dam. This era shows a working ranching and forestry landscape, noted by the Kistler Ranch and Burgeson Ranch, alongside a California Division of Forestry station near Keystone. The terrain is marked by the prominent Rushing Mountain lookout and the distinctive Red Hills, with the Sierra Road providing a primary transit corridor through the drainage basins of Dry Creek and North Fork Wildcat Creek. Isolated prospects and a claypit suggest the localized mineral interests that persisted into the early 1960s.
