1992 Map of Ackerson Mountain

About this map

Yosemite National Park and the adjacent Stanislaus National Forest converge on this map, highlighting a transition from managed timberlands and early settlements to protected wilderness. The area around Hazel Green Ranch and the Tuolumne Grove marks a historic intersection of early travel routes and natural monuments, featuring the noted Tunnel Tree. The landscape is defined by the deep canyons of the Tuolumne River and its forks, which influenced the placement of early outposts like Peach Growers and the Carlon FS Station. To the south, Big Oak Flat Road provides a corridor through the high country, connecting the Big Oak Flat Entrance Station to high-elevation points like Gin Flat and the Crane Flat Lookout. The presence of the Yosemite Wilderness boundary reflects a commitment to preserving the drainage basins of Ackerson Creek and Crane Creek in their natural state.
