1955 Map of Lone Tree Creek

About this map

Hetch Hetchy Aqueduct cuts across the northern terrain of this quadrangle, a critical piece of California's water infrastructure threading through the ridges. The landscape is defined by the convergence of several major ridges, including North Ridge, South Ridge, and Smiths Ridge, which create a complex drainage system fed by numerous named springs. Mining history is evident at the Ladd Mine and the Buckeye Mines located near Buckeye Gulch, indicating the industrial activity that drew workers to these remote canyons. The map also delineates the jurisdictional boundaries where San Joaquin, Alameda, and Stanislaus counties meet. Historically significant water sources like Lone Tree Mineral Spring and Sulphur Springs are documented alongside natural landmarks such as Cedar Knob and Buzzard Roost, providing a detailed record of the physical and resource geography in the mid-1950s.
