Down the main pitch, in a rift, is 10m to a boulder pile in a chamber where the shorter route reenters, and a passage continues back north towards the entrance. South is a rift ending too tight. The main way soon leads to a pitch of 10m with a large ledge halfway. A short passage intersects a cross-rift before becoming too small (with a draught), but down the rift drops c15m to a choke at about -45m.
Re-explored and surveyed in 1999 - see log-book write-up – but apparently never drawn up.
