This last section, between the Gartnerkofel and Mount Carnizza, goes through the same Carboniferous rocks present at Mount Corona. Here, unlike Mount Corona, they are sharply southward tilted. It is because of the various and numerous Alpine faults that separate the two rocky masses. Moving for a short distance along the path that descends from the summit of Mount Carnizza towards Mount Corona, you can reach a wide sedimentary structure, visible just below 1900 m. It bears witness to a gigantic “water spill” that occurred from the sandy marine sediments of 300 million years ago. The weight of the sediments applied pressure on the deep deposits and the water contained between the sand granules was squeezed upwards. Going upward, it broke and bent the still soft upper layers, which were already compact but not cemented.
