1940 Map of Evey Canyon

About this map

The San Gabriel Mts rise sharply above the developing community of Claremont in this 1940 edition, reflecting a landscape defined by the steep transition from mountain wilderness to the alluvial fans of the Los Angeles basin. Angeles National Forest lands cover the high terrain, where a distinct Firebreak and the Camp Baldy Line indicate the region's historical efforts to manage fire risk. The presence of the Lower San Antonio Guard Station at the mouth of San Antonio Canyon underscores this area's role as a critical watershed and recreational gateway.
