My contractor has been saying we were due for a break. It may have come today. I started digging the trench for the foundation that goes under the all important shear wall, when 3 inches down, Clunk....I moved the shovel, 3 inches down, clunk. A footing emerged, with rebar protruding, the correct size etc. It saves a bit of digging and some concrete. We're going to fill the void with concrete.
The picture did not come out as clear as I would have hoped. Oh well.
