Back today at the same archaeological site where I was on Monday, working in little intact areas between the concrete foundations, utility trenches, and other disturbances. Above, a view of the area where we made today's discoveries. Not very promising, but you can see the Potomac River in the background.
In one of our units we found a pit that seems to contain all or most of a large ceramic pot, broken into pieces, along with cooking stones and enough charcoal to get a radiocarbon date. It's probably 700 or 800 years old.
And then below the pit we found this large stone tool, maybe a hoe. I'll have another picture when it comes out of the ground.
