About this map

Hazel Green Ranch and the isolated Peach Growers settlement sit at the western edge of this high-country landscape, where the Stanislaus National Forest meets Yosemite National Park. The topography is defined by the deep canyons of the Middle Fork Tuolumne River and its various tributaries, including Ackerson Creek and Crane Creek. The transition from forest service land to protected wilderness is marked by the Yosemite Wilderness boundary, which encompasses the high ridges of Crocker Ridge and peaks like Ackerson Mountain.

Logistics and park administration are centered around landmarks like the Big Oak Flat Entrance Station and the Carlon FS Station. To the south, the Tuolumne Grove stands near the intersection of major high-altitude routes like Tioga Road, while the sprawling Ackerson Meadow provides a rare level opening in the otherwise steep terrain. The presence of the Crane Flat Lookout suggests the critical fire-watch infrastructure necessary for this heavily timbered region during the late twentieth century.
