Disappointment Valley anchors this high-desert landscape in southwest Colorado, where the transition from open basins to forested plateaus is marked by the boundary between the Uncompahgre National Forest and the San Juan National Forest. The geography is defined by complex drainage systems, with Disappointment Cr and various arroyos like Pine Arroyo and West Branch Pine Arroyo carving through the terrain. Human modification for agriculture is evident in the presence of the Horseshoe Ditch and Custer Ditch, which manage water in an otherwise arid environment.
