The Via GeoAlpina is a joint project of the Alpine countries launched in the framework of the International Year of Planet Earth 2007. The aim of the project is to make the public aware of the geological, geomorphological or hydrological highlights along the various routes of the ViaAlpina from Trieste to Monaco.
Two stages of the Via GeoAlpina lead right through the World Heritage, Swiss Tectonic Arena Sardona.
The first one leads from Weisstannen to Elm. On this stage, one can observe a geological phenomenon of world dimensions: the Glarner Hauptüberschiebung. This shapes the landscape along the route and is clearly visible on the mountain flanks.
Further information you will find here.
The second stage from Elm to Linthal leads through an impressive landscape with a mountain panorama in which the Glarus main overthrust is again particularly visible. The first part offers breathtaking views of the legendary Martinsloch and the Tschingelhörner, which mark the border between the cantons of Glarus and Graubünden.
