Walk into a scanned boulder, block, slab, stump or log and you stop at the surface you see. All 25 scanned rocks, logs and stumps have a solid shape now, where a granite erratic used to let you walk in until your eyes were at its middle. You can no longer walk up a big boulder’s side like a ramp, and cliffs, walls and tors keep their hollows and overhangs open.

A blow counts when the pick is visibly on the stone. At the edge of your reach the swing leans in, or bends lower, until the point goes in, and a swing that stops on a log, a wall or an animal no longer pays out ore from the rock behind it. Ore rocks that were being judged as animals, so that no blow did any work, take the pick like any other rock.

A granite boulder takes nine swings, gives a stone at each, then falls apart into two to four more, and E picks them all up. The stones at the foot of a rock on a slope sit on the ground instead of hanging in the air, and the big gray boulders in meadows can be mined.

Still open on October 31: a very low rock could be out of reach from straight on, and small stones in talus and on open ground could not be picked up. Each blow then cut a flat slice off the rock; since November 3 the pieces break on rough faces.
