Swiss Tectonic Arena Sardona
The Swiss Tectonic Arena Sardona
in the north-eastern part of the country covers a mountainous area of
32,850 ha which features seven peaks that rise above 3,000 m. The area
displays an exceptional example of mountain building through continental
collision and features .excellent geological sections through
tectonic thrust, i.e. the process whereby older, deeper rocks are
carried onto younger, shallower rocks. The site is distinguished by the
clear three-dimensional exposure of the structures and processes that
characterize this phenomenon and has been a key site for the geological
sciences since the 18th century. The Glarus Alps are
glaciated mountains rising dramatically above narrow river valleys and
are the site of the largest post-glacial landslide in the Central Alpine
region.
