This is one of 30 American Indian rock art sites located in the state of Kansas. The majority of the sites are located in four counties in the central part of the state. Smaller numbers are located in southeast and southwestern Kansas. These sites have examples of anthropomorphic figures and human-like forms, animals and animal-like forms, geometric designs, straight lines, and grooves. Several styles of anthropomorphic petroglyphs have been recognized. Previous analysis of a fraction of this rock art indicates it is the product of Indian tribes inhabiting Kansas during the protohistoric and historic periods of circa AD 1541 to AD 1870.
