I also picked up a nice squash knife, quill flattened or pottery tool, scraper, broke blade and a very wierd re-notched point. It looks as though the point broke at the original notch and someone quickly added a new one.
Awesome artifacts! I'm sure that point would still function and do what it was made to do. Otherwise; those are some really nice finds and the workmanship is superb. !
I was fortunate enough to have Mr. Larson send me a buffalo scapula. I could see wear along the wide part and figured it was an agriculture tool. I thought the Mandan probably had a variety of bone and stone spades. Thanks for the info. You guys are great.
