GeoPark Sarganserland-Walensee-Glarnerland, around the best lake in the world to understand immediately that mountain building the way you were told in school is a lie.

Not so long ago, in the days of the dinosaurs, there were no mountains on Earth.
So the northshore top was still touching the southshore.

Then the northshore was suddenly uplifted, 1900 meters higher above, leaving in the middle the deepest lake in the new area that would be known a few thousand years later as the Alps.
