The Riesending cave on Untersberg mountain is the largest cave of Germany, being currently 21.3 km long and 1149 m deep. After the accident of Johann Westhauser in June 2014 and the difficult rescue that was covered by the media all over the world, meanwhile the exploration of the cave has resumed. During the last years the deepest regions of the cave were in the focus of exploration. Final sumps could be reached in Krakencanyon (-1149 m), Auencanyon (-1148 m) and lately in Suppendunstgang near Krötenhalle (-1080 m). In parallel to the exploration the cave is cleaned up from the remains of the rescue and meanwhile it can be considered clean below Bivouac 3 (-700 m).
