1948 Map of Mariposa

About this map

Mariposa and the high Sierra Nevada are documented here just after the war, showing a landscape defined by its transition from the Central Valley foothills to the jagged peaks of the Cathedral Range. The map details the early post-war infrastructure of Yosemite National Park, featuring the Glacier Point Hotel and the Crane Flat Ranger Station along the historic Tioga Road. Further east, the high desert and alpine lake country around Mono Lake and Crowley Lake are clearly delineated, including the complex water systems of the Long Valley Reservoir and Hetch Hetchy Reservoir. Local history is preserved through labels for smaller mining and timber era settlements like Mormon Bar, Ahwahnee, and Nipinnawasee. The presence of the Southern Pacific RR near Raymond and Knowles Junction illustrates the transportation networks that linked these mountain communities to the valley below, while industrial markers like the Blind Spring Mill point to the region's mineral heritage.
