John Aylott, Rod, Dave (NTTSCC) Rachel, Quackers.
Three interesting “collector’s items” in the National Tower Testing Station Quarry. Chelm’s Combe Quarry Cave and Box Cave are both extremely well decorated – the latter with a fairly large chamber. Reynold’s Rift is tight and wet-ish with a desperate dig in a choked sump at its bottom. How the hell John manages to drill 3’ slotholes down here I will never know! Nice to wash off in the firm’s own washroom after the trip.
