Piz Dolf, right, from the east end of the Fil de Cassons about the Bargistal seen time. The summit is quite right. Good visibility, the thrust line; this is also in the foreground; greenish Verrucano on light limestone.
Piz Dolf from low to high, as seen from the Fuorcia ( rom = saddle) Raschiglus upper Segnesboden. The summit is the somewhat inconspicuous second cusp of the right
The Piz Dolf, also Trinserhorn, is a 3'028 m above sea level. M. high mountain on the border between the Canton of Grisons and the Canton of St. Gallen in Switzerland. The summit is - as well as that of the neighboring Piz Sardona, Piz Segnas and also the Fil de Casson - from the ancient rocks of the Verrucano blanket that was pushed in folding of the Alps on the much younger Flyschschichten that form the base of the mountain. This striking thrust fault is listed as a UNESCO World Heritage Site.
Piz Dolf is the Roman name. The German name Trinserhorn not from the community Trin, which was Romansh -speaking, but probably from the St. Galler Calfeisental.
The summit is located south of Sardonahütte and can be reached via the Sardona Pass. An access of Flims forth along the Segnasgletschers is now possible without committing the glacier. Both routes meet in the north-west flank. At the top of the Grisons communities Flims and Trin and the St. Gallen municipality Ragaz meet.
Who can be satisfied with the sight of the mountain, you can do this from Fil de Cassons from; either after a climb through the Bargis Valley and below the south flank of Piz Dolf through ( in the picture is the path in the vegetation visible ) or via the Alpweg the Flimserstein or from the Segnas Hut forth across the Segnesböden.
