Actually the pass does not have a distinct name. It is the signpost just nearby the dead-end hiking trail that has Belchenflue written on. The mountain is also called Bölchen by locals. The name came originally from Celtic from the sun god Belenus. The namegiving nearby peak (el. 1099 m.) was an important marker for the tribal calendar establishing the seasons. Along with the peak of the same name in Alsace (Alsatian Belchen) and Black Forest (Black Forest Belchen), it allowed the establishment of the winter and summer solstice.[1] As is the case with much of the Jura range, the cliffs are formed of hard oolithic limestone, which has been exposed as the softer stone above it has eroded. The pass forms the divide between the watershed of the Aare in the south and the Ergolz in the north. Both flow into the Rhine. To the east are the Challhöchi and Unterer Hauenstein passes.
