And speaking of looting of ancient artifacts. I worked with a guy named david (can't think of his last name) who lived right next to the creek on signal mountain that goes and forms rainbow falls at point park. directly down from where the creek crosses the road (before the signal mountain leaf fill) is a natural cave/bluff/overhang. It's hard to reach from the falls because you have to climb rock cliffs.

Him and his family took buckets and buckets of ancient indian artifacts from this natural shelter.
