About this map

Patterson Crossing serves as the focal point of this arid landscape, where the management of water dominates the human footprint. The map documents a sophisticated network of irrigation infrastructure designed to divert water from the Purgatoire River, including the Lewelling McCormick Ditch and the Patterson Ditch. These man-made channels reflect the agricultural necessity of the region, cutting across the terrain to sustain local land use near the prominent Purgatoire Canyon.

The surrounding geography is defined by a series of drainages and arroyos that feed into the river system. Significant watercourses such as San Francisco Cr, Frijole Cr, and San Isidro Cr carve through the plateau. This 2016 survey captures the intersection of natural erosion and human engineering, connected by local routes like Co RD 30.7 and Co RD 22 that navigate the varied elevations of the Las Animas County backcountry.
