2018 Map of San Guillermo Mountain

About this map

Los Padres National Forest encompasses this high-elevation terrain in Ventura County, where the landscape is defined by the prominent peak of San Guillermo Mtn and the long expanse of Lockwood Valley. The map details a complex network of seasonal and perennial watercourses, including the upper reaches of Piru Cr and the westward-flowing Alamo Cr. A single paved artery, Lockwood Valley Rd, provides access through the valley, connecting remote canyons like Wagon Road Canyon and Park Canyon to the broader region. This late-2010s survey captures the area's preservation as a protected wilderness, characterized by steep ridgelines such as Pine Mtn and remote water sources like Pine Spring. The presence of numerous creek branches, including Beartrap Cr and Piedra Blanca Cr, illustrates the drainage patterns vital to this part of the California coastal range.
