On the outskirts of Questenberg, strange rock formations were discovered during ground work in the 1920s near the former entrance to the Questenhöhle. Their appearance reminded people of the glacial potholes of the Alps and they initially assumed that these were comparable phenomena. It was only later that the true character of the holes and fissures in the gypsum rock, which were up to three meters deep, was recognized. The water from the Nasse created these impressive soil structures - with the help of harder material such as pebbles. The whirlpools of the river, which today flows around 10 meters further down the valley, worked the stones into the soft plaster. You can see the result of this work today as you climb the karst hiking trail to the Queste.

On the climb to the Queste you pass the glacier potholes. There is also an information board about the history of the glacier potholes and a seating area.
