That helps. I wouldn't have a clue about Illinois, but lookin it up they have some scattered temporary paleo sites, but one big one in Jersey County. I would say your find is Paleo. Good to know the location of a find, as you can go back and check the research of that area and see what people were known to be there. Of course, you might make a find that establishes the presence of people in an area that were never thought to be there. Cool find, and keep checkin that spot.
