Schöllenen Gorge and the Devil’s Bridge

Photographer: Michela Meda
Summary Author: Michela Meda; Stu Witmer

The Schöllenen Gorge, shown above, is an excellent place to see the
effects of the collision of the African and European
tectonic plates. It’s located in the canton of Uri, Switzerland,
between the municipalities of Göschenen in the north and Andermatt in
the south. The gorge is situated on the Ruess River in the southern
part of the Central Aar Granite, a granitic batholith that
intruded about 300 million years ago. Up to 1,968 ft (600 m) in
depth, the gorge shows the fracture systems brought about primarily
by uplift and shear as the continents moved together.

An impediment to travel throughout human history, bridges have been
built across the gorge since the 13th century. The first stone bridge,
called the Devil's Bridge, was built about 1585. Photo taken August
11, 2020.
