is only 13.5 km away to the northeast. The pass lies between the Grubigstein (2233 m) on the northwest, the Wannig (2493 m) on the southeast, and the Loreakopf (2471 m) on the west.
History
The pass was created when a huge mountain slide (actually the collapse of an entire mountain, with an estimated volume of 1,000 km3; the third-largest mountain slide ever in the eastern Alps) filled part of the valley to a height of 300–400 meters, distributing its boulders up to 16 km away. While it was initially believed that this had happened at least 12,000 years B.P. as a consequence of the strong temperature increase and intense run-off after the end of the last deglaciation, pollen analysisPollen analysis
