Irrigation infrastructure dominates this portion of the San Luis Valley, where the Trinchera Canal and the Highline Canal snake through a landscape defined by an extensive grid of county roads. The importance of water management in this arid agricultural region is further evidenced by the presence of the Sangre de Cristo Ditch Number 3 and the Willow Cr Reservoir in the southeast. While much of the terrain is characterized by these systematic road layouts and water courses, the Basaltic Hills provide a distinct geological contrast in the west. This 2013 survey illustrates the modern rural layout of the region, tracing the intersection of geographic features like Ojito Cr with the organized human imprint of numbered roads and the Cervante landmark.
