The hiking tour from the mountain station of the Brigels-Crest Falla cable car to the Biferten Hut and the mountain lake behind Mt. Péz d'Artgas reveals impressive evidence of the region's geology. The handy guidebook leads you on this hiking tour to places where you can practically retrace the origins of the Alps and recognize their geological strata. In the lime stone strata near the Biferten Hut, even the untrained eye can discover fascinating fossilizations. On the return to Brigels, you will encounter once more Europe's highest primeval pine forest, the Uaul Scatlè.

This hiking tour leads you on a mountain trail from the Alp Quader lookout point to the 250 to 300 million-year-old Verrucano rock formations towards the Biferten Hut. To the west, the Piz Tumpiv, consisting of Punteglias granite and Verrucano, rises to the heavens.

On a mountain trail, the hiking tour proceeds from the Alp Quader lookout point to the Biferten Hut on ground harboring Verrucano stone formations that are 250 to 300 million years old. To the west, Piz Tumpiv, consisting of Punteglias Granite and Verrucano, rises into the sky. From Rubi Sura, you will have a wonderful view of Val Frisal Valley, which was formed by the glacier. To the west of Val Frisal, almost the entire geological history of the earth ranging from 250 to 30 million years ago, when the Surselva was still under water, becomes evident. In some of these limestone layers you can even find fossils. Your destination is the mountain lake behind Piz d'Artgas. After pausing for lunch from your backpack, the hike leads you back to Rubi Sura, and on a steep trail through the valley formed by glaciers, to Rubi Sut. On the way to Brigels, you will discover Punteglias Granite that was uncovered by the trailside. The glaciers have formed the environs of the village of Brigels. The wall of moraines running through the village evidences this impressively.
