It's been said that the prehistoric story of America is many times more convoluted than the little we know at present. At the rate things are being discovered, things that were simply bypassed in the rush West, it might be that the history is a thousand times richer than what we know about now.
Kind of like "keniwic (sp?) man", huh? I agree. There ARE wonders to be discovered and those already discovered that haven't been seen by many in the USA. Near where I live are the most amazing sand dunes that stretch for hundreds of miles in length but are only a few miles wide. They are thought to be the "beach" of the prehistoric inland sea that covered much of the Great Plains.
