False1623-267100m up the 204 path from 157 and 0/5, turn right and drop into small valley leading to entrance. This entrance was found by CUCC in 1987, but was not given a number because a carbide pig was found at the entrance and taken to be evidence of previous or ongoing exploration. The entrance was then lost for many years (except briefly when Brian Outram refound it and took the carbide pig, without realising its significance). At one point it was postulated to be the same cave as Bogenhöhle, but was finally relocated in 2007.
Looking up valley towards entrance (halfway up on right).
