The main (first) entrance is a 2m x 0.5m shaft around 5m higher and 7m away from a larger, snow-plugged shaft (the second entrance), which in turn is just above a snow field, a little higher than the Eishöhle path. Both entrances lie on an obvious fault line which heads uphill for around 100m. If the fault line is followed up to just past a squeeze through bunde, you can turn left for around 100m to reach the entrance to 1623/136, Steinschlagschacht.A third, horizontal entrance is found by heading down to the snow filled shaft (the second entrance) and traversing left beneath a small cliff for around 20m. This leads to a low, unobvious hole at foot height, noticed because it was draughting out quite strongly. There is a surface survey to this third entrance from the first entrance.
