About this map

The Margarita Mountains dominate this coastal and inland transition of San Diego County, surveyed just as the region began a major military transformation. The landscape is defined by vast landholdings and ranching estates, most notably the sprawling Rancho Santa Margarita and several family-named properties like Johnson Ranch and Ferrante Ranch. Coastal life centers on the rail corridor where the At&Sf Rr skirts the Pacific Ocean near Las Flores, providing a vital link for the small settlements of Stuart and Oceanside North Base.

Inland, the Santa Margarita River carves a path toward the sea, passing near De Luz Station and the community of Fallbrook. Significant local landmarks include the Margarita LO lookout atop Margarita Pk and several water features such as O'Neill Lake and Whalen Lake. This survey captures the rural character of the backcountry before the rapid mid-century expansion of nearby Marine Corps installations.
