Douglas serves as the focal point of this borderland survey, positioned directly against the international boundary of the United States of America and Estados Unidos Mexicanos. The town's grid expands toward the northwest into Pirtleville and the settlement of Calumet. This landscape is deeply shaped by its industrial heritage, most notably marked by the Copper Queen Smelter situated west of the main town site.
