The San Pedro River corridor near the international border defines this 1952 topographic study, showing a landscape shaped by both water management and rail transportation. At the small settlement of Stark, the Southern Pacific railroad parallels the river valley, providing a critical transportation link through Cochise County. The presence of Diversion Dams along the river highlights early attempts to manage water for local agriculture and livestock, supporting isolated outposts like S-O Ranch and Valley View Ranch. Most notably, this map illustrates the precise line of the United States-Mexico border and the boundary between Arizona and Sonora, where the terrain transitions from the river bottom into the surrounding desert washes like Green Brush Draw.
