1996 Map of Otay Mountain

USGS Topo · Published 2002

About this map

The San Ysidro Mountains dominate this 1996 survey, where high ridges and deep canyons meet the international border. This map offers a rare dual-nation perspective, documenting the transition from the Otay Mountain Wilderness in San Diego County to the diverse network of settlements in Baja California. In the north, the Dulzura Community Center and family-named landmarks like Donohoe Mtn and the Donohoe Mine signal the area's early mining and community roots. South of the border, the topography falls toward the Río Tijuana and the Aqueduct, where small communities such as Santa Martha, Valle Redondo, and Los Aguajitos are linked by Telegraph lines and trails. The map tracks the convergence of Cottonwood Creek and Tecate Creek in Marron Valley, a significant watershed juncture that has shaped the human geography of this borderland region for generations.
