1935 Map of Whitaker Peak

About this map

Whitaker Peak dominates this mountainous 1930s landscape, where the sheer density of contour lines reveals the sharp verticality of the northern Transverse Ranges. This survey by Alfred Jones and the Los Angeles County Board of Supervisors captures the rugged divide between Los Angeles and Ventura Counties. The storied Ridge Route Highway snakes across the northeastern ridges, serving as the primary inland link for motor travel through these canyons before modern interstate alignments. Below the peaks, remote outposts like Agua Blanca Camp and Slayback Camp sit along the winding course of Piru Creek. The map documents a wilderness transition, showing the boundary where the Santa Barbara National Forest meets the Angeles National Forest, with the Piru Ranger Station providing a lone point of institutional presence in the south.
