<underground_description>Entrance gully of 5m leads to 20m pitch at 70&deg; over snow, heading roughly back towards Eislufth&ouml;hle. At the base is a 'snow-duck' under a rock wall beyond which a small rift-like chamber descends about 3m. Straight ahead at the same level, the rift quickly becomes an impenetrable slot through which can be seen a 2m wide passage with an ice floor running down from right to left at 5-10&deg;. This is the source of the strong draught. Below the slot is another low hole, this leaks a vague draught and leads to a small boulder-strewn ledge with a definite blackness continuing to the left behind more boulders. Energetic but nervous removal of these gave obvious signs of a continuation, but other commitments and rain prevented a return. Note therefore it has been <strong>Left Going</strong>.</underground_description>
