1949 Map of Triunfo Pass

About this map

The Santa Monica Mountains meet the coast in this topographic study, where deep ravines like Little Sycamore Canyon and Nicholas Canyon carve through the steep terrain of the Topanga Malibu Sequit. Human presence is concentrated along the shoreline and a few winding mountain routes, with the Roosevelt Highway tracing the edge of the Pacific Ocean past Solromar and Leo Carrillo State Beach. Education for the mountain communities is centered at the Yerba Buena Sch and Decker Sch, while fire protection is evidenced by the Triunfo Lookout and Lachusa Fire Patrol Sta. The map highlights the intersection of the Ventura and Los Angeles County line, crossing high points like Sandstone Pk and descending through Sequit Creek to Sequit Point. The 1967 photorevisions, shown in purple, reveal the gradual expansion of roads such as the Mulholland Highway into these previously remote coastal ridges.
