I was browsing through my photos and came across some images that I had not shown to anyone yet, so I thought I'd post them. The rockpile above is on the Miner Farm at Tomaquag.
Above is another image from the Miner Farm, this time it's a rock-on-rock. The shape certainly reminds me of some kind of animal head.
Piles of stones make up the above row at the Miner Farm. The arm and leg belong to Bob Miner. The rockpile above was found on a site near Rte. 3 in Hopkinton, RI. It sits near the lone boulder you see pictured below.
