Sevenmile Plaza serves as the focal point for this rural agricultural landscape in the San Luis Valley. The terrain is defined by an extensive and complex network of water management features essential for high-altitude farming. The Rio Grande flows through the southwestern corner, feeding a sophisticated system of irrigation works including the Farmers Union Canal, the Monte Vista Canal, and the Rio Grande and Piedra Valley Canal.
