The high desert terrain of the Tecate Divide and In-Ko-Pah Mountains defines this 1959 survey of San Diego County, where the southern California landscape meets the Mexican border. The map documents the scattered high-altitude communities along the highway corridor, including Live Oak Springs, Manzanita, and Boulevard. The geography is split between tribal lands, including the Manzanita Indian Reservation and Campo Indian Reservation, and private developments like the Calexico Lodge.
