Portjenhorn from Weissmies-SSE-Ridge

Rocky peak, pyramid shaped and placed at the junction between the valleys "Antrona", "Saas" and "Zwischbergen".

It's the highest peak of the chain watershed from "Montemoro pass" to the "Zwischbergen pass"; and it's the southern peak of the massif almost totally in Swiss region composed from north to south by Fletschorn,Lagginhorn and Weissmies. Magnificent pyramid from the Italian side but a long crest not very impressive if seen from the Almagellertal(Saas side). It is formed by three main rocky ridges. The first two, on the border crest from the Porta di Loranco to Andolla pass, where they fall on the Italian side with numerous jagged ridges that enclose remains of ancient almost extinct glaciers.

The Italian side hosts the major and difficult routes. While, the northern ridge divides the valley of Saas from the valley of Zwischbergen.

Both flanks covered by glaciers, which are the Rotblattgletscher (west side) and the Zwischbergengletscher (east).

The Italian name of the mountain, derives from its Andolla homonymous belower pastures. The sense of the Swiss name, should be: "Portjengrat", "Portjen-ridge", "Ridge of Porta (di Loranco)".

The arrival on the top of the Andolla is always an emotion, thanks to the engagement, the attention, the labour. But must not forget that the top is not the end of the excursion because the descent is longest and more difficult.
