View from Hochhäderich (1565 m) in NW direction to the Prodel-Kojen range with Kojen (1300 m) on the left side and Fluh (1391 m) on the right side. This chain of low mountains consists of conglomerate rocks, locally known as Nagelfluh. They have their origin in sediments transported out of the early Alps which later consolidated, and were folded and tilted due to tectonic forces. Hennenmoos, on the territory of Austria, is shown on the left side.
