Did you know, that Triberg…
… with its mighty granite blocks lies in the so-called "Triberg granite massif"?
… with its surrounding mountains was covered by glaciers in the crack ice age about 150,000 years ago, of which the “Bergsee” still bears witness as an ice age niche?
… with its southern mountain ranges borders on the main European watershed between the North Sea and the Black Sea?
