"Rockage"

We are digging in a part of the build site where there is a lot of rock on the surface.  Most of our rock is limestone and the rocks that are buried are almost always rust colored.  But the ones that have been lying on the surface for the past few thousand years have weathered to a lovely grey color.  I have been saving a number of these for future landscaping projects.

These two big rocks were recently removed from our excavation.  Note my hat for scale.
Some day I want to set them up as standing stones a' la Avebury.

Smaller pretty rocks I add to this pile.
