About this map

Inyo National Forest and Kings Canyon National Park meet along the dramatic crest of the Sierra Nevada in this early 1950s survey. The high-altitude landscape is defined by the South Fork of the Kings River and the winding John Muir Trail, which traverses through Pinchot Pass and Sawmill Pass. To the east, the terrain drops sharply toward the Owens Valley, where the settlement of Aberdeen sits near the base of the mountains.

Mining activity is concentrated in the eastern canyons, with several named operations including the Sierra View Mine, Glacier Mines, and the Ruby Mine situated near Armstrong Canyon. The presence of the Division Creek Powerhouse and several springs, such as Harry Birch Springs and Graver Anton Spring, highlight the essential role of water management in this arid transition zone. Geologists and local historians can trace the intricate network of pack trails connecting high-country meadows like Sawmill Meadow to the valley floor.
