An article about native stone sites appeared in our local paper today. Quoted in it are Fred Werkheiser, Chief Bob Red Hawk Ruth, and Tim Powell of the Penn Museum. Apparently with the cooperation of Fred and some Indians, the museum is carrying out research at what sounds like the Oley Hills site. A picture of one of the cairns at Oley Hills appears on the first page of the article, which may be found here. Unfortunately only part of the article is online.
This is exciting, because this is the kind of research that would have to be done in order for entities like the Archaeological Conservancy to be willing to spend money on sites like this. Of course the research could prove inconclusive, but this is a huge step in the right direction!
