1932 Map of Red Rover

About this map

The San Andreas Rift Zone slices across the northern portion of this 1932 survey, creating a distinctive linear landscape within the Angeles National Forest. This era in Los Angeles County's history is characterized by isolated rural outposts and the nascent infrastructure of early automotive travel. The terrain is dominated by the Sierra Pelona range and the high Sierra Pelona Valley, where specialized services like Boiling Point Garage, Summit Garage, and Valley Garage supported travelers navigating the steep elevation changes. Remote family operations such as Ritter Ranch and Letteau Ranch appear alongside spiritual and industrial sites, including the Christ Faith Mission and the Red Rover Mine. The presence of the Puritan Mine (Abandoned) suggests the shifting economic priorities of the region as mining gave way to ranching and transport.
