1955 Map of Lone Tree Creek

USGS Topo · Published 1972

About this map

The Hetch Hetchy Aqueduct cuts across the northern landscape of this quadrangle, illustrating the massive mid-century water infrastructure required to support California's coastal cities. This survey of the tri-county border area where San Joaquin, Alameda, and Stanislaus counties meet reveals a land defined by complex ridge systems like North Ridge, Pegleg Ridge, and Smiths Ridge. Local industry and resource extraction are evident at the Ladd Mine and Buckeye Mines, while the presence of numerous water sources such as Lone Tree Mineral Spring and Sperry Springs highlights the critical importance of water rights in this arid terrain. The map's network of jeep trails and canyons, including Hospital Canyon and Hellsinger Canyon, documents the historical access routes through the Diablo Range before modern development altered the rural character of the region.
