As part of an exploration of ice tower ridge, Harry, Nial and Aaron found a lousy hole in the snow and climbed down into it. Inside was a narrow (1.5m max), shallow (3m max) void which extended about 15m downhill, narrowing eventually to the point that it was no longer passable. No clear vent was found. At first it was decided not to leave a temperature sensor in this cave, but after finding 2009-11 too dangerous to enter with available equipment, the team returned to 2009-10 and left a tinytag down there.
