1938 Map of Black Mountain

USGS Topo · Published 1948

About this map

The wild, high-altitude landscape of the Los Padres National Forest dominates the eastern portion of this survey, which captures the sharp transition between Los Angeles and Ventura counties. Topography here is defined by the steep drainage of Piru Creek, which flows through a complex network of ridges and narrow valleys. This specific sheet focuses on the eastern margin of the broader Tejon region, where the terrain rises toward Dome Mtn and descends into the deep cuts of Beartrap Canyon. A solitary Spring is noted near the canyon floor, a vital resource in this arid, high-elevation environment. The lack of roads or settlements emphasizes the undeveloped character of these mountains in the early 1930s, showing the land before modern infrastructure began to penetrate these remote sections of the Transverse Ranges.
