Entenloch Gorge

The Entenloch Gorge (German: Entenlochklamm) is a 2.5-km long water gap of the Leukental in the Bavarian-Tyrolian border area between Kössen and Ettenhausen bei Schleching.

Coming from the south, the Großache cuts through a transverse mountain range of steep rocks, reaches the border at the pilgrimage site Maria Klobenstein, and from then on is called the Tiroler Achen.

Geology

The Großache rises on the northern edge of the Kössen valley between the mountains Rudersburg (1434 m) in the west and Rauhe Nadel (1266 m) in the east on several transverse and steeply placed bars of Rhaetian limestone and Jurassic rock. It is the southern border of the Oberwössener depression, which goes from Rauschberg bei Ruhpolding via Kössen to Niederndorf on the Inn. In these resistant layers, the Großache has only been able to create a gorge-like passage since the last ice age. On the Austrian side, the pilgrimage church Maria Klobenstein is located above the gorge in a depression made of weathered layers. A huge rock deposited by a landslide gives the church its name.[1]

One of these ridges forms the natural border between Germany and Austria.[2]

Widening of the gorge

Several extreme floods of the Großache in the area of Kössen and St. Johann in Tirol have occurred since the 16th century. The disaster of 1899 was responsible for the planning of a large flood control project. In 1902, the county of Tyrol commissioned the regulation of the Großache.[3]

Earlier, the Entenloch had a narrower stretch with a width of about 3.4 meters. During heavy rainfall and snowmelt, tree trunks would become wedged in the gorge, causing flooding upstream in the Kössen valley basin. The Großachen regulation from 1906 to 1922 achieved a widening of this area to 12 meters. The blasting for this took place in 1906 and 1907.[4][5]

Hanging bridge

A hanging bridge over the gorge led to a historical smugglers' path, on which residents of the border area transported cigarettes, alcohol, and coffee in order to avoid customs duty. The bridge was destroyed by driftwood during the 2013 European floods.[6]
