About this map

Santa Monica Mountains dominate this 1950 coastal survey, where the steep canyons of Guadalasca and El Conejo meet the Pacific Ocean. The landscape is defined by its dramatic relief, from the high elevation of Sandstone Pk and the Triunfo Pass down to the rugged shoreline at Sequit Point and Bass Rock. Settlement is sparse, concentrated near the coast at Solromar or tucked into upland areas like Nicholas Flat.

Infrastructure in the mid-century consists primarily of narrow mountain roads and rural institutions, such as the Yerba Buena Sch and Decker Sch. The fire protection network is visible through the Triunfo Lookout and Lachusa Fire Patrol Sta, essential for managing the brush-covered terrain of Topanga Malibu Sequit. Transportation follows the winding Yerba Buena Road and Mulholland Highway, while the Pacific Coast Highway hugs the base of the cliffs.
