About this map

The Angeles National Forest San Gabriel Mountains dominate this 1934 topographic study, revealing a landscape defined by extreme relief and early mountain industry. Miners and ranchers carved out a precarious existence along the steep drainage basins, leaving behind sites like the Stanley Miller Mine, Allison Mine, and Baldora Mine. These mining operations are situated near prominent peaks such as Rattlesnake Peak and Iron Mtn, highlighting the intersection of geological exploration and industrial ambition in the high country.

Water management and forest administration are evident through features like the Cattle Canyon R S and numerous named canyons including Devils Canyon and Bichota Canyon. Human settlement is represented by small outposts such as Webers Camp, Williams Camp, and Thompsons Ranch, which served as hubs for early mountain recreation or resource extraction. The complex network of the West Fork San Gabriel River and East Fork San Gabriel River forms the backbone of the region's geography, providing a clear view of the area's natural hydrology before significant modern developments.
