The platform was designed by the Chur architect Corinna Menn on behalf of the municipality of Flims and inaugurated in September 2006. It consists of a single pillar that is anchored in two places. The pillar, held back by a traction cable, protrudes into the gorge. On the pillar lies the triangular platform made of larch wood, which gives the structure the shape of a swift.

The highest point of the Kunkels Pass is 1,357 meters. It was probably already used in Roman times.

Lake Cauma, the Pearl of Flims Called "Lag la Cauma" in Romansh, which means "Lake of Midday Rest," Lake Cauma is the pearl of Flims. Origin This mountain lake was formed as a result of the largest landslide in the Alps, which occurred almost 10,000 years ago. The formation of the lakes is attributed to prehistoric landslides. The water seeped through the porous rockslide masses. However, it can also dissolve the limestone with the help of its carbonic acid. Over time, it created an underground passage. A deeper, impermeable clay layer ensures that the water does not completely seep into the ground. Text / Source: Flims Laax Falera https://www.caumasee.ch/geschichte/

Ruinaulta Rhine Gorge The Ruinaulta or Rhine Gorge is a gorge up to 400 meters deep and around 13 kilometers long in the Vorderrhein between Ilanz and the mouth of the Hinterrhein near Reichenau in the canton of Graubünden in Switzerland. The Romansh name 'Ruinaulta' is composed of the two words Ruina (scree slope, quarry) and aulta (high). The Ruinaulta was created after the Flims landslide almost 10,000 years ago. At that time, over 10 billion cubic meters of rock broke off between the Flimserstein and the Piz Grisch and buried the Vorderrheintal between today's villages of Castrisch and Reichenau under a mass of rubble several hundred meters thick. Since the Vorderrhein could no longer drain, a lake was dammed over a length of around 25 km. Over time, the river cut deep into the landslide masses and the resulting lake was able to drain completely. What remained was the Ruinaulta with its steep limestone rubble cliffs in impressive erosion formations. Text/Source: Wikipedia https://de.wikipedia.org/wiki/Ruinaulta
