The United States Mexico border defines the southern edge of this landscape, where the international boundary line cuts across the high ridges of Tecate Peak. At the base of these mountains, the settlement of Tecate sits adjacent to the Customhouse, serving as a critical point of transit between California and Baja California. Infrastructure for water and transport is a prominent theme, evidenced by the San Diego City Conduit winding through the northern hills near Dulzura Summit, utilizing a complex system of tunnels, siphons, and a flume.
