Mirage Cem sits on the western edge of a landscape defined by an intricate network of irrigation and water management systems. This modern survey reveals how the drainages flowing from the Rio Grande National Forest, such as Wild Cherry Cr and Rito Alto Cr, have been carefully harnessed for agricultural use. The valley floor is crisscrossed by family-named infrastructure including the Wales Shellabarger Ditch Number 1, Shellabarger Eaton Ditch, and Wales Travis Ditch. These features illustrate a legacy of land use where natural flows like San Luis Cr are diverted through complex channels like the Hoffman Niedhardt Ditch. The transition from the high-altitude terrain of Marshall Gulch to the managed wetlands of the San Luis Valley is captured through clearings and rugged pathways like the Rito Alto Trl.
