During the late Jurassic, this dolostone was formerly at the sea floor, but after millions years of tectonic movements and natural forces, these rocks now appear at 3000m! Mont Blanc, the highest peak of the Alps is less than 20km away, and is visible in the background. Thank to the Alpine collision, this former sea floor was thrusted over gneiss and granite to make both geologists and mountaineer ...[Read More]
