1940 Map of Valyermo

About this map

The San Andreas Rift defines the dramatic meeting point between the high desert and the steep northern slopes of the San Gabriel Mountains in this 1940 edition. While the Antelope Valley to the north shows a grid of agricultural development and early roads like Avenue W, the canyon floors are dominated by sprawling family holdings such as the Aldrich Ranch, Pallett Ranch, and Valyermo Ranch. This era of land management is well-documented through the presence of the Valyermo Ranger Sta and a CCC Camp, highlighting federal infrastructure within the Angeles National Forest during the late Depression years.
