No, I found these at the site that I posted info about in the signs and symbols diagnosed thread. I haven't posted them there yet. I noticed this rock overhang and that it would have made a pretty great shelter, so I decided to check under it. These rocks were just under the top layer of debris, pretty much exactly how they sit in the picture. There are a couple more that go with them that aren't in the picture. They look to be of a completely different composition than the ledge covering them. What are your thoughts?
