About this map

The San Diego River watershed defines this Southern California landscape, which was surveyed just before the 1940s. At the center of the region's agricultural and social structure is the Edgemoor County Farm near Santee, while the eastern peaks are dominated by the El Capitan Reservoir and the Capitan Grande Indian Reservation. The mapping captures a network of small ranching and residential pockets like Lakeside, Bostonia, and Glenview, all connected by U. S. Route 80.

Transportation is anchored by the San Diego and Arizona Eastern railroad, which skirts the valley floors. Further into the foothills, the Sequan Indian Reservation and various family-named outposts like Featherstone Ranch and Grable Ranch reveal the dispersed settlement pattern of the era. Higher elevations toward El Cajon Mtn and the Cleveland National Forest show evidence of industrial activity at the Daly Mine and a local Prison Camp near the dam.
