Pointe de Chalune, Alpine summit in Bellevaux, France

Pointe de Chalune is a 2,116 m summit in the Chablais Alps, on the commune of Bellevaux in Haute-Savoie. It forms the western end of the frontal fold of the Brèche nappe, where erosion exposes the successive layers of the anticline in cross-section. The upper part is a jagged crest of grey sedimentary rock, with steep grassy and rocky slopes below and patches of snow in the gullies.

Pointe de Chalune lies at the western end of the frontal fold of the Brèche nappe, the Roc d'Enfer anticline. Erosion there exposes the anticline's successive layers in cross-section: the Roc d'Enfer belongs to the upper Brèche, the Pointe de Chalune to the lower Brèche, and the Pointe de Chavasse to the underlying Median Prealps nappe. The contact between the two nappes lies northeast of the Col de Vésinaz.

The name Chalune may come from the local patois word calonna, meaning a sheltered slope, or from calane, a steep rocky slope; it may also share its origin with the word caillou, pebble. Hikers reach the summit from the col de Chalune, itself accessed via the col de la Ramaz or from La Chèvrerie through the hamlet of Pététoz.
