2018 Map of Groveland

About this map

Groveland and the historic settlement of Second Garrotte anchor this modern survey of the Sierra Nevada foothills, where the landscape is defined by the legacy of hydraulic mining and the engineering of California's water infrastructure. The Hetch Hetchy Aqueduct cuts across the center of the quadrangle, passing through the Second Garrotte Basin as it moves toward the valley. The map details the transition from high-density development around Pine Mountain Lake and the Pine Mountain Lake Airport to the wilderness of the Stanislaus National Forest. Significant terrain features such as Jackass Ridge, Hells Hollow Ridge, and Wagner Ridge frame deep drainages like Jackson Gulch and Whites Gulch. In the south, the boundary between Tuolumne County and Mariposa County follows the rugged terrain near Greeley Hill, while the Tuolumne River winds through the northern reaches, illustrating the region's complex network of creeks and valleys.
