About this map

The Sespe Condor Sanctuary dominates much of this landscape, reflecting late 20th-century conservation efforts within the Los Padres National Forest. The terrain is defined by deep drainages like Agua Blanca Creek and Piru Creek, which flow toward the northern reaches of Lake Piru. Human presence is marked by a series of remote campsites and ranching history, notably at the Whitaker Ranch (Site) and the Log Cabin Campsite.

The border between Ventura Co and Los Angeles Co traverses the steep ridges, connecting prominent landmarks such as Cobblestone Mountain and Whiteacre Peak. Local geographic curiosities include the narrow passage of Devils Gateway and the Hole-in-the-Wall Falls along Hopper Creek. This 1991 survey shows the area largely preserved from modern development, maintaining its character as a protected wilderness and watershed.
