About this map

San Guillermo Mountain stands as the central landmark in this high-elevation region of Ventura County, where the Los Padres National Forest landscape is defined by deep canyons and seasonal watercourses. The northern portion of the map is dominated by the broad expanse of Lockwood Valley, a high-country basin accessed via Lockwood Valley Rd. This area reveals a sparse pattern of human activity centered around the Plush Ranch and the Boy Scout facilities at Camp Three Falls.

Southward, the terrain becomes increasingly complex as the headwaters of several significant drainages take shape, including the many-forked Piru Cr and Alamo Cr. A network of backcountry sites like Fish Bowls Campground, Haddock Campground, and Cedar Campground are linked by Forest Service routes such as 9n03 and 8n40. This 2012 survey illustrates the contemporary management of this wilderness interface, marking the various springs and campgrounds that serve as vital nodes for modern recreational use in the California backcountry.
