1947 Map of Mariposa

About this map

Mariposa and its historical mining district are documented here in the late 1940s, showing a landscape defined by the Mother Lode's legacy and early Sierra foothills development. The map details important gold-era landmarks such as the Mariposa Mine and the Granite King Mine, alongside established settlements like Mormon Bar and Bootjack. The rural social fabric is visible through numerous one-room schoolhouses, including Sebastopol School, Chowchilla Sch, and Ben Hur Sch, many of which served isolated ranching communities before mid-century consolidation. The southern portion of the quadrangle follows the Chowchilla River into Madera County, capturing the transition from the high ridges of Horsecamp Mountain to the flats at Bailey Flats. This survey preserves the exact alignment of the All-Year Highway and Raymond Road during an era when the Sierra National Forest boundary marked the limit of the region's ranching and mining expansion.
