About this map

Gold mining history and water infrastructure define this mid-century survey of the Stanislaus National Forest. The landscape is dominated by the Tuolumne River and its various forks, including the Middle Fork Tuolumne River and South Fork Tuolumne River. Evidence of the region's mineral wealth is scattered across the terrain, with operations like the Gold Queen Mine, Kanaka Mine, and Hazel Dell Brothers Mine marking the hillsides. The Hetch Hetchy Aqueduct cuts through the southern portion of the map, appearing both as a surface feature and a tunnel through the granite.

Industrial activity centers on Tuolumne, where the Sierra RR terminates near the Providence Mine. Outside of the larger settlements of Groveland and Arastraville, the area is characterized by isolated homesteads and family holdings such as Murphy Ranch, Quinn Ranch, and Rogge Ranch. The presence of the State Fish Hatchery and the Oakland Recreation Camp highlights the shift toward conservation and public recreation alongside the established extraction industries.
