1949 Map of Triunfo Pass

USGS Topo · Published 1958

About this map

Santa Monica Mountains topography dominates this coastal landscape, where steep canyons carve toward the Pacific shore. At the edge of the sea, the settlement of Solromar sits along the Roosevelt Highway, serving as a rare point of human habitation in a region defined by its drainage systems like Arroyo Sequit and Big Sycamore Can. Higher in the peaks, infrastructure of the late 1940s is represented by the Yerba Buena Sch and Decker Sch, alongside fire prevention sites like the Triunfo Lookout and Lechuza Fire Patrol Sta. The map highlights the early development of famous thoroughfares, including the winding Mulholland Highway and Yerba Buena Road, which navigated the difficult terrain of Boney Mountain and Triunfo Pass long before the modern expansion of Southern California coastal communities.
