Hidden Waters

Kurzbeschreibung

Flims Rockslide – Groundwater – Lakes, UNESCO World Heritage Tectonic Arena Sardona

Beschreibung

We hike across the debris of the Flims Rockslide, the largest landslide event in the Alps. Unique waterways have formed within the rockslide debris. The mysterious, turquoise-glittering lakes hidden in the forest offer us insights into this underground water network. From our meeting point, we enjoy a leisurely hike to Lag Prau Pulté, cross the Flims bypass road, and continue to Lag Prau Tuleritg and Lag la Cauma. At various stops, we will address questions such as: How was the age of the Flims Rockslide determined? How fast does groundwater flow? Why do the water levels of the lakes fluctuate?
