About this map

Cobblestone Mtn dominates this 1958 topographic survey, which documents the remote and largely undeveloped mountainous border between Ventura and Los Angeles counties. The landscape is defined by the steep drainage basins of Piru Creek and Agua Blanca Creek, revealing a network of seasonal camps and specialized outposts like Ellis Apiary Campground and Whittaker Ranch.

Mapping by the Army Map Service and the Geological Survey highlights the early conservation efforts within the Los Padres National Forest, including the designated Sespe Wildlife Area. Unique geographical features such as the Devils Gateway and The Pothole are clearly marked alongside primitive infrastructure, including the White Mountain Trail and several firebreaks. The presence of numerous benchmarks like BM 1893 near Log Cabin Campground reflects the intensive surveying required to navigate this complex terrain before the expansion of modern road systems.
