I call it "rubble" but some of it's useful. The old flat red bricks that were placed horizontally in the buttress and the large pieces of soft sandstone that the French call "tuffa" can be made into garden walls. The smaller fragments will make good filling for our potholes.
While working we saw and heard high to the south, cranes travelling due west, perhaps trying to skirt the Pyrenees. I tried to photo them but they were too high and too far away. They were no more than a faint cloud of dust against the blue sky.
