About this map

The Sierra Madre Mountains and the San Rafael Mountains converge in this 1942 military survey, revealing a landscape defined by deep canyons and high ridges in the heart of the Los Padres National Forest. The map documents a sparsely settled interior where large landholdings like the Sisquoc Ranch and Rancho San Juan occupy the rare flat ground along the Sisquoc River and Foxen Canyon.

Resource extraction and backcountry management are evident through labels like the Asphaltum Mine near Asphaltum Creek and the Barrel Springs Guard Station. The presence of several family-named outposts, including Adams Ranch, Colson, and the Diamond-T Ranch, alongside numerous canyons such as Buckhorn Canyon and Bear Canyon, provides a detailed record of the early 20th-century ranching and infrastructure within Santa Barbara County's rugged backcountry.
