1953 Map of Blackcap Mtn

About this map

The high Sierra Nevada backcountry, as mapped by the State of California Director of Water Resources and federal surveyors, reveals a landscape of high-altitude water management and wilderness recreation. The creation of Courtright Reservoir and Wishon Reservoir on Helms Creek and the North Fork Kings River signals the era's mid-century focus on hydroelectric power and storage. The map tracks the winding path of the John Muir Trail through Kings Canyon National Park, connecting the Glacier Divide and the Evolution Valley. Significant landmarks for high-country travelers include the Diamond D Ranch, Chamberlains Camp, and numerous named meadows like Blaney Meadows. The terrain is characterized by dramatic granite features such as Pavilion Dome and challenging crossings like Hell For Sure Pass, which provides access to the lake-studded Red Mtn Basin and the Devils Punchbowl.
