With Callum.

A successful and productive evening breaking-up boulders in the deep Soft South using plug and feathers method. After a quick lesson showing Callum how to use the kit, I drilled the holes and Callum split the boulders. There is quite a pile of rocks for the weekend team to shift out of the cave and add to the wall-building material stash.
