Minnesota pre-Clovis update A faithful reader send this article on the recent finds in that state that is generating some interest. Pictures, too, one of which I am hereby pilfering for display here:

Described as an "axe-like tool". Admittedly, that looks rather like retouch at the bottom, but it's hard to tell from the photo whether that shape is accidental or whether there is more retouching to get it to that shape (it seems like the former though). There is only mention of artifacts being found, no features (hearths) or anything else, which is a bit disconcerting.
