About this map

Agricultural precision and water management define this portion of the San Luis Valley, where the town of Center sits at the northern edge of a highly organized grid of roads and irrigation works. This high-altitude farming region relies on a complex network of man-made waterways, including the Rio Grande Drain, Hiline Lateral, and Raney Ditch, to support its operations. The landscape is marked by smaller named localities such as Ansel, Dunul, and Vastine, which reflect the historical distribution of farming communities and rail-side points across the valley floor.

Transportation and infrastructure are adapted to the flat terrain, featuring straight-line routes like Twelvemile RD and localized aviation facilities like Van Treese Airport and McCullough Airport. The map also captures the intersecting boundaries of Saguache, Rio Grande, and Alamosa counties, illustrating how political lines were drawn across this uniform, productive landscape. This survey provides a clear look at the contemporary state of Colorado's high-desert irrigation heritage.
