As a newcomer to this site and artifact hunting, I'd like to thank all those who have looked at and all those who have responded to my post in a thoughtful and informative manner. I posted these pictures of the pipe my friend found about seven years ago as a favor to her in case someone here had found something similarly crafted by a Native American. Previously she had been told by someone in the Archaeology Dept. at the University of Tennessee that it might have been carved by an African American before the Civil War because some African American pottery and walking canes contain similar snake motifs.
Today she informed me the culvert she found the pipe in drains a hollow that has a few old home sites but nobody has lived there for at least 30 years. That's all the info I have about the pipe's location and thanks again for the views and also the link to the Indian Map, the pottery pic with circles, the info on how the circles were made and the pic of the Choctaw pipe.
