1938 Map of Black Mountain

About this map

Los Padres National Forest dominates this 1932 topographic survey of the mountainous region along the border of Los Angeles and Ventura counties. The terrain is defined by dramatic elevation changes, captured through detailed contour work by C.W.H. Nessier, culminating in the prominent peak of Dome Mtn. Drainage patterns are clearly visible through the descent of Piru Creek and the branching path of Beartrap Canyon, offering a precise record of the watershed before mid-century changes.
