Here is Peter at another crossing. Looks like a "swimming" hole ahead.

I noticed some stone work and it turned out that it is some kind of pen? It's sort of a square about 15' x 15'. The walls are about 4 feet high and there is an opening on the stream side.

We cleared just a little of the growth covering the inner wall to get a better look. Still have no idea what it really is/was.
