1940 Map of Camp Baldy

About this map

San Gabriel Mts dominate this 1940 edition, where the high-altitude settlement of Camp Baldy serves as a central hub for canyon access and forest management. Surveyed in the mid-1930s by W. R. Chenoweth, the map reveals a landscape defined by steep drainages like Cattle Canyon and Coldwater Canyon, and the critical infrastructure of the Angeles National Forest. Mining history is evidenced by the Gold Dollar Mine and Eagle Mine situated high on the slopes. The era’s focus on fire prevention is clearly marked by the Camp Baldy Guard Station, several designated Firebreak lines, and the Sunset Peak Lookout. Rising to the northeast, San Antonio Peak 10059 marks the topographical climax of the San Antonio Ridge, overlooking a network of early mountain thoroughfares including Baldy Road and the Glendora Mountain Road.
