Domestic Archeology

I've been doing some digging, laying brick to enlarge my walkway and give me a bit more patio for the little house.  And in my digging I'm discovering river rock and slate.  These are a couple of photos of this work so far.  Most of the slabs of slate I've uncovered are too big for me to budge from their resting places, so I am using river rocks and brick to incorporate them into the patio I'm building without disturbing their resting places.
