Der Steinbockschacht, die östlichste 1000 m tiefe Höhle

Lukas Plan

Since 2011, Steinbockschacht has been explored and in September 2018 an international team of cavers surpassed the 1 km mark and reached a depth of 1037 m and a length of 2324 m. There are several continuations including ones that lead further down. The cave developed in Upper Triassic Dachstein limestone and dolomite as well as Middle Triassic limestone of the Grafensteig and Wetterstein Formation. It is characterised by a short horizontal part slightly below the entrance level and relatively deep pits (up to 250 m). Only at around 180 m below the entrance, the pits are separated by significant horizontal canyons. Speleothems are rare and notable deposits of fine-grained sediments only occur in the deepest parts. Further, the Hochschwab karst massif and its almost 1000 documented caves are characterised and its significance for the water supply of the city of Vienna are highlighted.
