Overstreet just never got out in this area. I checked out the local museums and collections and there's some killer Paleo points found locally. Don't know how they missed out in his book.
We're planning a trip out to the buffalo jumps and I talked to the land owner and there's been a lot of old points and blades found. They do allow hand digging and may be up for a screen dig if I can get TJ or Nacho to make the quick little jaunt up here.
The Montana jumps are excellent places to hunt points. Especially if on private land. In some places the bones are eight feet deep. A variety of blades can be found.I will look for your upcoming hand-dig report with many good pictures!
