Hooper and Mosca anchor this 1968 study of the San Luis Valley, where the landscape is defined by a rigid grid of numbered roads and an intricate irrigation network. The terrain is marked by a series of parallel east-west routes, including Elevenmile Lane through Fourmile Lane, which illustrate the systematic agricultural development of the region. Flowing through the eastern portion of the map is San Luis Creek, leading toward the edges of the Great Sand Dunes National Monument. Water management is central to the area's identity, evidenced by numerous features such as the San Luis Valley Irrigation Drain, Gibson Ditch, and Prairie Ditch. The prevalence of Flowing Wells across the quadrangle highlights the heavy reliance on artesian water for ranching and farming during this era of Colorado's history.
