About this map

Potrero sits at the heart of this borderland survey, positioned in the open expanse of Big Potrero Valley. This mid-century landscape is defined by its proximity to the United States Mexico international boundary, where the settlement of Tecate anchors the southwestern corner of the sheet. The area's infrastructure reflects a reliance on both water management and rugged transit, featuring numerous wells, a Gaging Sta, and a network of Jeep Trails cutting through the high country around Hauser Mountain.

Resource extraction and transit are evident in the presence of a Gravel Pit and the tracks of the San Diego and Arizona Eastern railroad. Small community hubs like Canyon City and the recreation-focused Picnic Lake Park provide local focal points among the valleys. The map documents a specific era of rural San Diego County, where topographic detail reveals a mix of ranching-era water sources and the geographic constraints of the California Baja California border.
