About this map

Kings River South Fork carves through the high granite country of the eastern Sierra, forming the boundary between Kings Canyon National Park and Inyo National Forest. This mid-century survey captures a landscape of intense geological relief and early 20th-century resource extraction. The eastern slopes are dotted with high-altitude mining operations such as Glacier Mines, Firecracker Mine, and the Kearsarge Group, while the Division Creek Powerhouse marks the industrial utilization of the steep drop toward the valley floor.

Recreational routes are well-established, with the John Muir Trail threading through notable milestones like Pinchot Pass and Glen Pass. The map details a labyrinth of alpine water bodies, from the sprawling Upper Basin to the clustered Kearsarge Lakes and Gardiner Lakes. Near the eastern margin, the small settlements of Aberdeen and Seven Pines provide context for the human footprint on the edge of the Owens Valley, while the complex ridge systems of Muro Blanco and the Kearsarge Pinnacles define the crest.
