Another 7no. holes to continue with the connection into the 'lower series'. The holes were drilled a little shorter than usual, c.350-400mm, only used-up two batteries. Peering down into the Tuck Shop, there are a lot of rocks that require capping at some time in the future. Lots of 'mossies' and midges in the cave.
All sounded good from Stal Bend, there was a satisfying tumble of rocks.
