I just thought of something else on the subject. Most of you probably already know this, but it may be helpful to some. When I first started looking for artifacts, I took the "high ground" aspect a little too far. Only looking on the highest points along streams etc. It dawned on me one day, that high ground can be any place higher than the water would be at floodstage. Once I realised this, I started finding things on a regular basis. I't works well in this area anyway. Sorry if I'm posting too much. I'm obsessed with this subject.
