In 2003, a few weeks after identifying the characteristic and recurring bird-human themes in artifact material at 33GU218 in Ohio, this author came upon the traditional Inuit/Yupik "transformation art" on the Internet.  It was noted with much surprise that this displays essentially the same apparently shamanistic themes, albeit in a much more virtuosic presentation.  Some cultural affiliation, however remote, seems unmistakable.  Shown below are Inuit/Yupik works in specific common motifs, along with lithic artifacts from the 33GU218 site incorporating the same thematic iconography.  Crude as it is in the stones, it is quite recognizable.  This should probably come as no surprise, given that similar shamanic-like imagery is very much evident in 20,000+ years BP Pleistocene artifacts of northeastern Asia (e.g. Siberia - see Early Art of the Northern Far East: The Stone Age by Russian archaeologist M. A. Kiriyak), Siberia being the presumed earlier residence and departure point of  most of the earliest migrants to North America.
