More induced rapid speleogenesis. Continuing the expansion of the narrow gap to the north of the current end of Merlin’s. Six holes, plus a shorter one for the trimmings, concentrated on the right-side. Some of the holes weren’t so easy to drill, the bit was binding, probably a calcite/mineral vein.
The task was brought to a satisfactory conclusion.
After a warm few days, I opted for cotton overalls, good choice, the cave is almost dry, just a small puddle along the haul and shuttle route, and still damp in the Tuck Shop, but I was comfortable.
Coming out of the cave, the heat is noticeable, still in the twenties at 21:00hrs.
