1950 Map of Margarita Peak

About this map

The Santa Margarita Mountains dominate this 1950 survey, defining a landscape of sharp ridges and deep drainage systems like San Mateo Canyon and San Onofre Canyon. At the heart of the terrain, Margarita Peak rises near the Margarita Lookout, serving as a focal point for the surrounding Cleveland National Forest. The map reflects a period of significant military presence, with the sprawling Camp Joseph H Pendleton Naval Reservation covering the southern half of the quadrangle. Early infrastructure is visible through the network of firebreaks and isolated landmarks such as a Windmill, while the presence of Tenaja Ranch and Las Flores hints at the ranching history that preceded and coexisted with federal land management. Notable high points like Horno Summit and Miller Mtn bracket the area's complex topography.
