About this map

Acton and Ravenna serve as the primary northern outposts in this landscape, situated along the Southern Pacific railroad corridor through Soledad Canyon. The terrain is dominated by the high ridges of the San Gabriel Mountains and the protected lands of the Angeles National Forest. For researchers of the region's industrial past, the presence of the Monte Cristo Mine tucked into the upper reaches of Mill Creek provides a clear marker of the area's mining history.

Water management and ranching operations are prominent throughout the drainage basins, with the Tujunga Dam and Little Rock Palmdale Dam anchoring the hydrographic network. Isolated outposts like Hoyt Ranch and Kentucky Springs represent the sparse settlement patterns typical of the mid-century high country. Topographic markers such as Strawberry Peak, Gleason Mtn, and Mt Lukens define the skyline, while the network of canyons like Arrastre Canyon and Aliso Canyon illustrates the complex natural corridors used for movement through the mountains.
