Kössen Formation

During the upper Triassic Age some 210 million years ago, Kössen formation emerged from the deposits in a shallow sea hardly exceeding a depth of 50m. Conditions were detrimental to life so that no bigger coral reefs could form. Only some smaller reefs emerged. Fossilized corals can be found as regular white structure in the Kössen strata.
Rocks found in the Kössen strata are very different from each other. The dark marlstones are good rocks for soil creation. Because of their high clay content they weather easily. They do not create summits but alpine pastures with an abundance of flowers. On the other hand dark or bright limestones can be included, which form steep escarpments and rock faces.
