1942 Map of Margarita Peak

About this map

The Rancho Santa Margarita y Las Flores land grant dominates this 1942 landscape, illustrating a transition from expansive ranching estates to military and residential development. Along the eastern edge, Fallbrook serves as a primary settlement, while the Atchison Topeka and Santa Fe Railway traces the coastline and follows the Santa Margarita River inland. This corridor is punctuated by small stops and facilities like the Deluz RR Station and the Stuart Siding Water Tank, essential infrastructure for the steam era. Rural life is anchored by family-named holdings such as Johnson Ranch, Sky Ranch, and Richman Ranch, alongside local institutions like the Deluz Sch and Deluz PO. Near the coast, the Horno Canyon CCC Camp reflects New Deal-era activity just prior to the area's intensive wartime transformation into a major military installation.
