Remote and beautiful, this is among the crown jewels of southeastern Colorado. The habitat is mostly lowland riparian, cliff/rimrock, and pinyon-juniper. For birders, this is among the best places to see Mississippi Kite, Ladder-backed Woodpeckers, Rufous-crowned Sparrow, and Western Screech-Owl. The variety of reptiles and amphibians at this site is among the best in the state. Bighorn Sheep can be seen here, particularly in winter.
