Pennine Alps
The Pennine Alps, sometimes referred to as the Valais Alps, are a mountain range in the western part of the Alps. They are located in Italy and Switzerland.
The Pennine Alps are amongst the three highest major subranges of the Alps, together with the Bernese Alps and the Graian Alps that include the Mont Blanc massif.
Geography
The Italian side is drained by the rivers Dora Baltea, Sesia and Toce, tributaries of the Po. The Swiss side is drained by the Rhône.The Great [St Bernard Tunnel], under the Great St Bernard Pass, leads from Martigny, Switzerland to Aosta.
Morphology
The main chain runs from west to east on the border between Italy and Switzerland. From Mont Vélan, the first high summit east of St Bernard Pass, the chain rarely goes below 3000 metres and contains many four-thousanders such as Matterhorn or Monte Rosa. The valleys are quite similar on both side of the border, being generally oriented perpendicular to the main chain and descending progressively into the Rhône Valley on the north and the Aosta Valley on the south. Unlike many other mountain ranges, the higher peaks are often located outside the main chain and found themselves between the northern valleys.Peaks
