1953 Map of Devils Postpile

USGS Topo · Published 1955

About this map

Devils Postpile National Monument serves as the central anchor of this mid-century high-country survey, capturing the complex geography where the Middle Fork of the San Joaquin River carves through the central Sierra. This era is defined by a landscape transitioning from pioneer-era resource extraction to a managed wilderness for recreation and conservation. The presence of the Minaret Mine on Volcanic Ridge and scattered landmarks like Bugg Cabin reflect the area's prospecting history, while the emergence of sites like Reds Meadow RS and the Minaret Falls Campground signal the post-war rise in backcountry tourism. Geologically, the sheet documents the jagged crests of Banner Peak and Mt Ritter, overlooking a dense network of glacial basins including Thousand Island Lake and Garnet Lake. For researchers, the map preserves old trail crossings like Sargent Crossing and established ranger infrastructure before modern expansion.
