A Rock Pile in the water?
And this is Jupiter's Boulder at Black Rock Forest:
A rather testudinate boulder on Peekamoose Mountain (are those hand tools below it?):
And some interesting standing stones at Shawangunk Mtn.
And I couldn't copy this one, but it might possibly be the "Tavern Stone" near the Schaghticoke Res, but I'm not sure. So click here for "Cairn on River by Schaghticoke:"
