Insights into the formation of the Alps
Nowhere else in the world are the processes of mountain formation more visible in the terrain than in the area around Piz Sardona in the border region between the cantons of St. Gallen, Glarus and Graubünden. Along the line visible from afar, the Glarus Thrust, 270 million year old rocks were pushed over a distance of 35 kilometers onto "only" 40 million year old rocks. Reason enough for the Tectonic Arena Sardona to be a UNESCO World Heritage Site today.
The Alps and Africa
How exactly did the mountains that characterize the Swiss landscape come about? Despite their fame, we know very little about this. One thing is certain: The Alps are a huge crumple zone that was formed when the two continents of Europe and Africa collided over 100 million years ago. A short film illustrates the various processes that ultimately formed our mountains.
Top hikes in the World Heritage Site
The Sardona Tectonic Arena runs right through the middle of the Heidiland vacation region. The best way to explore the individual hotspots of the UNESCO World Heritage Site is in hiking boots.
