One pretty good rule of thumb is.." where there's pottery there's points".. the fact that pottery is there usually means alot of time was spent there and it's not just a little lithic scatter at a campsite.
CRAP!!!!! That piece in the back, with those patterns...Thats what the big pieces i threw away looked like exactly! kicking my self now! I didnt realize what they were. There were about 5 pieces, around 4 to six inches. I may be able to find where I threw them. dang it. That map is helpful also. much better than the ones I found on wiki. I really appreciate everyone's willingness to tolerate a newbies ignorance and to be helpful in answering my questions. This is a great forum.
