Potrero sits at the northern end of this international landscape, where the high-elevation valleys of Hauser Mountain meet the international border. This mid-1990s survey illustrates a rural-industrial borderland defined by trans-boundary utility and communication lines, including a significant pipeline and a telephone line corridor. While the California side is marked by the rugged path of the Pacific Crest National Scenic Trail and the small communities of Canyon City and Division, the landscape transitions south into the Mexican state of Baja California. Here, the settlement pattern is characterized by numerous small establos and ranchos such as Establo la Paleta and Los Villarreal, situated among the deep drainages of Arroyo Seco and Cañada Joe Bill. The infrastructure supporting the city of Tecate is visible, including the C. La Panocha TV Tower and various water systems.
