1995 Map of San Guillermo Mountain

About this map

San Guillermo Mountain stands as the central landmark of this mid-1990s forest survey, which details a landscape where administrative boundaries and wilderness designations intersect. The northern boundary follows the Lockwood Valley Road, serving as a transition into the more developed Plush Ranch area, while the southern reaches are dominated by the extensive Sespe Wilderness. The drainage of Piru Creek and its various forks, such as the South Fork and Cedar Creek, define the complex topography. Historically significant access routes like the Wagon Road and the Piedra Blanca Trail are clearly mapped, indicating the long-standing utility of these corridors for both transit and backcountry management. This edition is particularly useful for identifying established forest facilities including the Fish Bowls Campsite and the Gaging Station located near the confluence of several seasonal canyons.
