About this map

Los Padres National Forest dominates this 1943 survey, revealing the remote high-country landscape along the Ventura and Kern County border. The map documents a period of early regional infrastructure, notably the County Industrial Road Camp near Apache Potrero. This facility reflects the era's focus on backcountry road development and land management within the national forest system.

The topography is defined by dramatic elevation changes, from the broad San Emigdio Mesa to the sharp ridges of Knife Edge. Vital water sources are meticulously plotted, including Nettle Spring, Mystery Spring, and Blue Rock Spring, which served as essential landmarks for surveyors and forest travelers. The drainage network is characterized by deep erosional features like Apache Canyon and Quatal Canyon, providing a clear record of the watershed before mid-century changes.
