The Swiss Tectonic Arena Sardona is a remarkable geological site that showcases the phenomenon of mountain formation through continental collision. It is distinguished by the Glarus overthrust, where older rock layers have moved above younger ones, a feature that has intrigued and challenged geologists for years. This area's unique geological history and its significance in understanding the formation of the Alps were recognized in 2008 when it was inscribed as a UNESCO World Heritage Site. The region not only offers a window into the Earth's deep past but also presents a stunning landscape for hikers and nature enthusiasts to explore.
