Here are some rock pile pictures from the site I visited this past weekend. The large boulder from the prior post is just visible in the background, between the trees. If you click on this picture, you can also see that rock on top of the rock pile a little better.
There is a "hollow" or "bowl" just off to the right of, yet not visible in, this picture.Two piles on boulders.
This was up the mountain from the site, but it's something I've seen a lot of here in NY. The middle boulder appears to be split and pulled forward. The entire structure is about 6 feet tall if you stand on the low side.
There were a few small rock piles on the summit. Here is one of them.
I've posted additional photos at the Two Headwaters blog.
