The Denver and Rio Grande Western Railroad cuts a sharp line through the San Luis Valley, anchoring the grid of La Jara and the nearby agricultural settlements of Richfield and Sanford. This high-altitude landscape is defined by an intricate network of water management, where the Alamosa River and La Jara Creek are diverted into numerous channels like the Richfield Canal, San Luis Ditch, and Morgan Drain. These features reveal the engineered reliance of the local economy on valley irrigation.
