About this map

The gold-bearing foothills of Mariposa County are meticulously detailed here in the early 1960s, revealing an landscape defined by its mining heritage and cattle ranching terrain. The settlement of Ganns serves as a central point along White Rock Road, which winds through a territory marked by numerous mineral extractions. Hard-rock history is evident in the cluster of workings such as the Great Northern Mine, Pocahontas Mine, and the colorfully named Toad Mine.
