2015 Map of Ackerson Mountain

About this map

Yosemite National Park and the Stanislaus National Forest dominate this landscape, meeting along a boundary that divides the high meadows from the forest’s managed timberlands. The terrain is defined by the steep drainage basins of the Middle Tuolumne River and the S Fork Tuolumne River, which carve through the Sierra Nevada granite. At higher elevations, the settlement of Aspen Valley and the open reach of Ackerson Meadow provide a stark contrast to the surrounding forested slopes. Along the southern edge, the historic passage of the Tioga Road / Big Oak Flat Rd winds through Crane Flat and past Gin Flat, marking the primary route for early travelers entering the heart of the park. This topographic study captures the area's network of forest routes, such as Evergreen Rd, and the distinct ridgelines of Crocker Ridge and Ackerson Mountain.
