1991 Map of San Guillermo Mtn

USGS Topo · Published 1991

About this map

San Guillermo Mountain and the high ridges of Pine Mountain dominate this corner of the Los Padres National Forest in Ventura County. This 1991 edition captures a landscape defined by deep drainages and recreation infrastructure, including the National Recreation Trail and remote outposts like Fishbowls Campsite and Haddock Campsite. The northern portion of the map transition into the Lockwood Valley, where Lockwood Valley Road serves as the primary artery alongside features like a Gravel Pit and a small Landing Strip. The map illustrates a complex network of seasonal water sources and landmarks like the Gaging Station on Wagon Road Canyon, detailing the hydrology of Piru Creek and its many tributaries before they reach lower elevations.
