1958 Map of San Diego

Moving inland, the terrain rises sharply into the Laguna Mountains and Cleveland National Forest, where water management systems like San Vicente Reservoir and El Capitan Reservoir supported the growing coastal cities. The transit infrastructure of the era is preserved in the tracks of the San Diego & Arizona Eastern Ry and the Atchison Topeka & Santa Fe Ry. To the far east, the map details the arid transition into Anza-Borrego Desert State Park and the Coyote Mountains, providing a view of the region before modern suburban sprawl moved into the inland valleys.
