Not sure what to call this stone. It is quarried near my house and use to make crushed gravel and used as hardcore under foundations and floors. Some of it is stratified. All of it is hard but somewhat brittle. I had put in broken 1/2 bricks and the like on the path around and into the house but it always looked dirty and uncleanable.
So i bought some chisels and split some of the stones and shaped some more and came up with this stone pathway over the timbrel vaulted bridge. next two the bridge I put up two columns and a rough cut reject lumber beam. Bernice wanted another place to put her flowers.
