Tour Sallière, Mountain summit in Valais, Switzerland.

Tour Sallière is a 3220-meter summit in the Chablais Massif with a distinctive pyramid shape composed of sedimentary rock layers. The peak rises prominently above Lake Salanfe, creating a recognizable landmark visible from the surrounding valleys.

The mountain formed through tectonic movements that pushed sedimentary rock layers upward over millions of years, creating its present structure. The geological processes that shaped it left behind visible layering in the rock formations that can be seen today.

The first ascent of the Tour Sallière was made in 1858 via the north-west face by H. Marguerat, J. Oberhauser, J. Rey and E. Gonet. In 1907 Émile-Robert Blanchet, Jean Chaubert, E. Revaz and A. Coquoz opened the direct east face. Climbers still follow these lines on the north-west side, including the Grand Revers, which rises more than 1,000 metres.

The usual approach follows the path past Lake Salanfe to the mountain's east side, where the 1858 first-ascent route climbs the north-west face. The serious lines, including the Grand Revers with over 1,000 metres of height and the direct east face climbed in 1907, demand alpine experience and a guide.
