Tschingelhörner with Martin’s Hole

The best-known view of the UNESCO World Heritage Tectonic Arena Sardona! At approx. 2 600 m above sea level, Martin’s Hole pierces the Tschingelhörner between Elm and Flims.

A transverse, dark marl layer and a steeply orientated fault surface (red) intersect at Martin’s Hole (click on the image above). In this area, erosion was able to remove the rocks more quickly and the hole with a diameter of more than 15 metres was formed.

On two days each in spring (13 / 14 March) and autumn (1 / 2 October), the rays of the sun hit the church of Elm through Martin’s Hole.
