About this map

Apache Potrero and the high mountain flats of the Los Padres National Forest define this 1940s landscape along the border of Ventura and Kern Counties. The topography is dominated by massive east-west drainage systems, most notably Quatal Canyon and Apache Canyon, which carve through the arid terrain. Human presence is sparse, marked by isolated outposts such as the County Industrial Road Camp and Dorman Ranch.

A network of seasonal water sources sustains the area, including Blue Rock Spring, Nettie Spring, and Mystery Spring. The map documents a rugged interior transition where the San Emigdio Mesa meets deep-cut ravines like Burges Canyon and Long Canyon. This survey, based on 1942 aerial photography, captures the primitive road network and cattle-grazing geography of the Cuyama Valley backcountry before modern infrastructure altered the accessibility of these high-desert canyons.
