About this map

The Santa Barbara Co Ventura Co boundary line bisects this rugged portion of the Los Padres National Forest, documented during the Second World War. High peaks like Monte Arido and Old Man Mountain define the drainage basins of the North Fork Juncal Creek and Matilija Creek. The terrain is characterized by steep canyons and prominent landforms such as the Three Sisters and La Carpa Potrero.

Remote land use is visible at the Upper Hartman Ranch near Abadi Creek, providing a rare look at mid-century ranching in these mountains before later development or landscape changes. Strategic water sources like La Carpa Spring and the Agua Caliente Creek served as vital points in a landscape dominated by steep descents into Canyon Diablo and Monetta Canyon. This survey, compiled from 1942 aerial photography, preserves the interior geography of the Los Prietos Y Najalayegua area as it stood in the 1940s.
