1933 Map of Sierra Madre
USGS Topo · Published 1933About this map
The San Gabriel Mountains rise sharply above the developing San Gabriel Valley, where the interface between the City of Sierra Madre, City of Arcadia, and City of Monrovia meets the southern edge of the Angeles National Forest. This 1933 survey reveals a landscape defined by canyons and early 20th-century mountain recreation, featuring numerous retreats such as Orchard Camp, Roberts Camp, and the First Water Resort. The intricate network of human activity in the hills is marked by the Toll Road, the Wilson Trail, and several Firebreak lines designed to protect the watershed. Infrastructure like the Santa Anita Dam and Sierra Madre Dam highlights the era's focus on water management for the growing communities below. Local resource management is also evident at the L A Co Nursery near Henninger Flats, reflecting the county's early conservation efforts within the steep terrain of Eaton Canyon and Santa Anita Canyon.
