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.
The careful planning of a tour will ensure that you also derive the maximum pleasure and enjoyment from it. Please take the time to contact the local information centre and enquire about route and weather conditions before setting off. Your intended trail may be fully or partially closed, depending on the time of year and weather conditions.
