Fortezza

The peaks, from left to right, are Piz Cambrena, Piz Palü and Bellavista. The high pass just right of center, between Piz Palü and Bellavista, is Fuorcla Bellavista. From there the route down to Berghaus Diavolezza over Fortezza descends south (that's to the left in the picture, which is taken from the west), over the big snow mass. Where the snow mass ends, follow the rocky ridge for quite a while, until you reach a suitable snow field on the eastern side (not visible of course) of the ridge to descend to the Pers Glacier. This should be near the left hand side of this picture. The picture coordinates are of Fortezza.
