Cooley knows what he's talking about. Marvin Rowe and Karen Steelman of the Department of Chemistry, Texas A&M University, have agreed to use their plasma-chemical extraction (PCE) method in an attempt to date samples of the polished rocks by direct AMS radiocarbon measurement (Rowe 2001; Rowe and Steelman 2002). To book a camping spot will cost you $35, but the premium sites are $45 per day.
