About this map

Antelope Valley meets the northern slopes of the San Gabriel Mountains in this 1934 survey, where the dramatic San Andreas Rift Zone carves a distinct geological path across the landscape. The map captures a transition from high desert alluvial fans to the steep, wooded canyons of the Angeles NF. Local water management is evident through the network of the Ditch system and Reservoir near Longview, supporting the scattered agricultural outposts of the era.
