About this map

The San Ysidro Mountains dominate this borderland landscape, defined by a sharp divide between San Diego County and Baja California. The international boundary is traced as it follows the course of the Tijuana River and Tecate Cr near Marron Valley. High-altitude features like Otay Mtn and Donohoe Mtn overlook a series of steep drainages, including O'Neal Canyon and Bee Canyon.

Transport and water sources are concentrated in the northern and eastern portions of the map. Doghouse Junction serves as a notable landmark in the interior mountains, while the area surrounding Dulzura Cr is marked by a network of local roads such as Campo Rd and Flume Rd. Springs such as Echo Spring, Donahoe Spring, and Lupe Spring point to critical water points in this arid terrain, situated alongside seasonal landmarks like Mine Canyon.
