Again just a short distance up valley from B3, a significant shakehole with snow at foot. (Cambridge Underground 1977 gives bearings of Loser 234°, Bräuning Nase 292°. However, Loser is not visible from this area and it is most likely that this bearing is to Sommersitz, which looks rather similar from this direction.)
