Getting some compass readings so we could try to match this up with topo and usgs maps would be fun too.I agree, that's what the ones in the pictures are, but I'm not sure about this one's original purpose and location. It is definitely not in line with the tramway from Shaker plant to dam. Perhaps it was moved from elsewhere prior to filling the lake? It is certainly a large structure to move without dis-assembling. I recall one leg is busted up, with a gap that would make a standing structure unsound.
I guess I need to go have another look
