1965 Map of Pine Mountain

About this map

Granite Station serves as the primary landmark in this mid-1960s survey of the California foothills, where the landscape transitions from open flats to more complex drainage networks. The map documents an economy driven by resource extraction, clearly marking the Round Mountain Oil Field in the southwest and several hard-rock operations including the Long Tom Mine and Poso Mine. The rugged character of the area is defined by the winding course of Poso Creek and its many tributaries, such as Grimaud Creek and Five Dog Creek, which cut through the terrain toward Poso Flat. This edition captures the infrastructure of the era, from the winding Granite Road to the high-elevation Radio Towers, while also preserving small details for local historians such as a remote cemetery and numerous spring-fed water sources scattered across the slopes of Pine Mountain.
