Farmers Union Canal and the Gibson Ditch define the agricultural water management of this high-altitude landscape in Saguache County. This 2016 survey shows a strictly rectilinear grid of rural routes, including Co RD 57 and Co RD G, which navigate the San Luis Valley's vast open stretches. The infrastructure is characterized by an extensive system of secondary irrigation channels such as the N Lateral, N Central Lateral, and Lateral Fortyseven. These features indicate a highly organized land-use pattern centered on controlled water distribution. Local naming, seen in roads like Peppers Ln and Holly Dr, provides a human scale to the large-scale township and range divisions of t42n r9e and t41n r10e.
