About this map

The Santa Ana River corridor and the high ridges of the Cleveland National Forest define this landscape during the late 1990s. The map captures the transition from the developed riparian zone near Featherly Regional Park to the deep, canyon-cut interior of the Santa Ana Mountains. Significant water management infrastructure is evident at the Santiago Reservoir, also known as Irvine Lake, which is held by the Santiago Dam.

Tracing the rugged interior canyons reveals a history of resource extraction and isolated homesteading, with the Black Star Coal Mine and Hidden Ranch tucked away from the coastal plains. Land grants like the Santiago de Ana Grant and Lomas de Santiago Grant underpin the local geography, while prominent peaks such as Sierra Peak and the high Whiteside Ridge offer a look at the topographical spine of the region before further modern encroachment.
