About this map

Mount Bullion and the surrounding gold-rich slopes of the Mother Lode dominate this mid-century topographic record of Mariposa County. The landscape is defined by its deep mining history, with operations like the Pine Tree Mine, French Mine, and Josephine Mine clustered near the Merced River. Further south, the settlement of Bear Valley serves as a local hub, featuring the Bear Valley Sch and a dedicated Bear Valley Sub-Station.

Evidence of historical land use is visible in the scattered garden plots and flats, such as Pendola Gardens, Trabucco Gardens, and Washington Flat. The rugged topography transitions from the river canyon floor up to heights like Fremont Pk and Telegraph Hill. Aviation infrastructure also appears near the southern edge of the quadrangle at the Mariposa Airport and the nearby Airway Beacon, marking the era's technological footprint in the Sierra foothills.
