The site contains evidence of long and diverse human occupation through prehistoric and historic periods.  The location offered a permanent water supply and a variety of natural shelters along the projecting bluff.  The site also contains a large array of rock art whose range of styles demonstrates the evolution of rock art through time.  An 1868 skirmish here between soldiers of the U.S. 7th Cavalry and Cheyenne Indians was the last historically documented Plains Indian / military engagement in southeastern Colorado.
