About this map

The Angeles National Forest dominates this landscape, where the steep terrain of the San Gabriel Mts falls away from the towering San Antonio Peak 10059. At the heart of the canyon network lies the settlement of Camp Baldy, a vital mountain retreat and gateway to the high country. The map documents the complex infrastructure of the early 20th-century forest service, featuring the Camp Baldy Guard Station and the Sunset Peak Lookout perched atop Sunset Peak.

Resource extraction and early recreation routes are clearly visible, with the Gold Dollar Mine and Eagle Mine situated in the upper reaches of the drainage. A network of fire prevention is evidenced by numerous Firebreak lines cut across the ridges, while the Glendora Mountain Road provides a primary transit link. The map captures the hydrography of the region through named drainages like San Antonio Canyon and Coldwater Canyon, illustrating the vital watershed management that defined this era of Southern California's development.
