About this map

Los Padres National Forest contains a complex network of high peaks and drainage basins along the border of Santa Barbara and Ventura counties. Compiled from 1987 aerial photography, this topographic record details the high-elevation terrain around Old Man Mountain and Monte Arido, where the headwaters of several significant drainages originate. The map illustrates a landscape defined by sharp elevation changes, with Sespe Creek and Matilija Creek cutting through the interior.

Evidence of historical land use and early ranching appears at the Upper Hartman Ranch and the named canyon of Agua Caliente Canyon. The southern portion of the sheet transitions into the Los Prietos y Najalayegua land grant area. This survey provides specific locations for water sources critical to the region's history, including La Carpa Spring and Abadi Creek, which have long sustained life in these remote mountain corridors.
