The possible hammerstone has undergone similar scrutiny with identical results. Evidence of modification to this stone included seven cones of percussion, all limited to a single poll of the stone, possibly indicating that it was used as a hammer (Ray 2000:70). While it is impossible to determine if these objects were ever used together, Ray and Lopinot argue that they were likely used to smash the bones of mastodons and other large game. They compare these to similar artifacts found at other suspected pre-Clovis sites such as Cooperton, Oklahoma; Bonfire Shelter, Texas; and the Lamb Spring site in Colorado (Ray 2000:70).
