About this map

Pyramid Lake serves as a massive focal point in this 1974 revision, which documents the critical water infrastructure and mountainous landscape along the Ventura and Los Angeles county line. The complex engineering of the California Aqueduct is prominently displayed, featuring the Gorman Creek Siphon and Side Hill Siphon as they navigate the varied elevations of Hungry Valley.

Isolated outposts like Lane Ranch, Kinsey Ranch, and the Bailey Homestead reflect the scattered human presence amidst the expansive protected lands of the Angeles and Los Padres National Forests. Historical backcountry access is visible through the network of the Piru Creek Trail and Buck Creek Trail, connecting remote points such as the Buck Cr Guard Sta and Hardluck Campground. The map also captures the topography of Black Mtn and White Mountain, showing the headwaters and springs that feed into Piru Creek.
