About this map

The Santa Monica Mountains dominate this 1900 survey, presenting a complex landscape of ridges and deep canyons reaching the Pacific Ocean. This specific edition, developed by the Oil Map Association, features an unusual overlay of arbitrary township boundaries and section lines across lands that were not formally sectionalized by the General Land Office, including large land grants like El Conejo and Guadalasca.

Coastal geography is defined by a series of south-running drainages such as Arroyo Sequit and Escondido Canyon, terminating at landmarks like Dume Pt. Early inland settlements are sparse but significant, including Newbury Park and the stage stop at Triunfo. The map documents the high peaks of the range, from Sandstone Pk on Boney Mountain to Castro Pk, providing a primary record of the terrain before the mid-twentieth century development of the Malibu coast and the Conejo Valley.
