1972 Map of Otay Mountain

USGS Topo · Published 1974

About this map

The San Ysidro Mountains define this international border landscape in the early 1970s, where steep ridgelines and deep canyons meet the United States Mexico boundary. The map documents the high-elevation terrain of Otay Mountain, a site of critical communication infrastructure as evidenced by multiple Radio Towers and the Otay Mountain Truck Trail. At Doghouse Junction, these specialized access roads converge, providing a look at the technical and defensive management of the high ground overlooking the Tijuana River.
