1940 Map of Evey Canyon

USGS Topo · Published 1942

About this map

The San Gabriel Mts rise sharply above the developing community of Claremont, marking a dramatic transition from the alluvial fans to the high peaks of the front range. This 1940 edition captures the canyon-country infrastructure of the era, focusing on the steep drainage of Evey Canyon and the primary transit corridor through San Antonio Canyon. The presence of the Lower San Antonio Guard Station along Camp Baldy Road indicates the importance of fire management and forestry oversight during this period, reinforced by the numerous mapped firebreaks etched into the ridgelines. Near the southern edge of the mountains, the Norton Sch serves the outlying residential areas where Pomello Dr extends toward the mouth of the canyon. The map clearly delineates the Los Angeles Co San Bernardino Co boundary line as it follows the course of the San Antonio Wash downstream.
