About this map

Courtright Reservoir and the high alpine basins of the Sierra Nevada define this 1962 landscape in Fresno County. This era captures the region's character as a primitive wilderness managed by the Sierra National Forest and Kings Canyon National Park. The survey details the high-altitude topography where the San Joaquin River and Helms Creek carve through granite peaks, featuring the remote Muir Trail Ranch and segments of the legendary John Muir Trail.

Glacial features are prominent throughout, from the Blackcap Basin to the strikingly named Hell For Sure Pass. For the researcher, the map documents the established backcountry infrastructure of the mid-20th century, including Chamberlains Camp and numerous meadows such as Blayney Meadows and Post Corral Meadows that served as crucial milestones for packers and early mountaineers navigating the Goddard Canyon and Piute Canyon routes.
