The picture of the Scotrun chamber in a wall that Norman mentions is here. The question being asked the day I saw it was whether it was a chamber to receive the sunlight on a certain day or days or if it was for offerings of some kind.
The Monroe County site in my last few posts is just a few miles away from Scotrun, but seems to be a completely different kind of site. Scotrun is on a hillside, while all the rock piles at the other site are in a flat, low area.
If I could I would spend time examining the whole area near these sites and documenting anything I find, but I don't drive. What we need is a grad student!
