1936 Map of Redrock Mtn.

About this map

The Angeles National Forest dominates this mid-1930s landscape, centered on the heights of Redrock Mtn. This survey captures the vital infrastructure of the era, from the winding Ridge Route to the extensive Telephone Line and various fire-prevention features like the Firebreak and Fire Line. Human activity in these mountains is reflected in small outposts such as Kelly Ranch and Naylor Place, while the 1920s-era Shelter House and Cienaga Camp provided essential stopovers in the backcountry. The map also documents the Gillette Mine, a testament to local extraction efforts. Geologically, the terrain is defined by a complex network of drainages including Castaic Creek, Fish Canyon, and Cienaga Canyon, which carve through the high elevations of Liebre Mountain and Red Mountain.
