Same here and for a neighbor of mine who has collected arrowheads by the bucketfuls. He has a better collection of arrowheads, spear points, gaming stones, drills than a lot of museums I've visited. He even has a pipe he found along the shore of the Tennessee River. This area of SE Tennessee was home to many projectile makers as is evidenced by all the flint shards you find anytime you turn dirt over. They apparently had an ongoing trade system with a lot of tribes, some of which weren't so local. I'm told that the origin of some flint found here can be traced to as far away as Michigan. I'm always on the lookout when I plow my garden spot. I found one 5" spear point in a neighbor's garden and had it dated by a local Archaeologist to approximately 11,000 BP. Pretty neat.
Pipestone, from a certain quarry in Minnesota, has been found far and wide.
“dated by a local Archaeologist to approximately 11,000 BP.”
What?
Well, duh. It's famous for being in Michigan.
