About this map

The San Andreas Rift Zone bisects the northern reaches of this high-altitude landscape, creating a distinct geological trough where Jackson Lake and Appletree Flat are situated. Surveyed in the mid-1930s, the map documents a transition in land use within the Angeles National Forest, where industrial mining footprints like the Big Horn Mine on the eastern flank of Mt. Baden-Powell exist alongside early 20th-century recreational outposts.

Social and youth organizations established a significant presence in these elevations, seen in the Boy Scout Camp and Girl Scout Camp located near the northern ridges. The steep drainage systems are meticulously detailed, from Vincent Gulch to the complex headwaters of the San Antonio Falls. Small stopping points such as Fenner and Barrel Spring provide evidence of early travel routes through the high passes of the San Gabriel Mountains.
