Here's an interesting little artifact that we found on a Pre-Dorset site in Nunavut this summer. Its an endscraper, with a smooth working edge and deeply serrated hafting area. A lot of the diagnostic tools from this particular site had serrated bases. It was my first time seeing this sort of treatment on bases, but I guess it does show up in the early Palaeoeskimo toolkits.
