A long drive to see not much.

An outcrop with a wedged splitnext to a broken down pile. I wasn't sure whether or not to photo it.Then one nicer example of a split wedged rock:
Then I walked over hill and dale, to find only a very faint hint of a site where an outcrop faced north into a wetland. A little pattern with a "manitou" shaped rock-on-rock.
[Note the rock to the left. I think it is part of the pattern]

In the background...a solitary rock pile:Closer:
