I used to live in NH. Moved to Indiana a year ago for work. Went to UNH in Durham.

There were, of course, native americans in Durham. They manufactured points out of stone, but I don't know the exact type in that area. I found a point north of there that was out of quartz.

I believe it was quite common for native americans to trade in things like points and also raw stone materials, so points found in one area may be made from material that came from some distance.

There may be some good folks to talk to at UNH re. native americans in the area. Contact the archaeology dept. and tell them what you're up to. They'll probably help you out.
