About this map

The San Andreas Fault cuts a definitive line through this high-altitude landscape, marking the structural divide between the San Gabriel Mountains and the desert floor. In the southern portion, the high ridges of the Angeles National Forest drop into recreational and seasonal flats such as Appletree Flat, McClellan Flat, and Big John Flat. This area, centered on the community of Big Pines, is characterized by the high-elevation geography of Table Mtn and Blue Ridge.

Transitioning north, the terrain gives way to the alluvial fans of the Antelope Valley, where the Governor Edmund G Brown East Branch California Aqueduct flows as a critical infrastructure artery. Residential growth is evident in settlements like Mescal Hts, while numerous canyons such as Jesus Canyon and Boneyard Canyon drain toward the north. The proximity of Jackson Lake to the primary fault line illustrates the unique geologic character of this transition between national forest wilderness and burgeoning desert communities.
