The Rio Grande and Conejos River converge in this high-altitude landscape along the border of Alamosa and Conejos counties. The terrain is defined by a sophisticated network of irrigation infrastructure designed to manage the water of the San Luis Valley, including the Sanford Ditch, Tenfoot Lateral, and the Conejos River Diversion. These man-made watercourses reflect the area's agricultural dependency and the complex engineering required to sustain life in this arid basin.
