| Easiest route | The mountain is easily climbed from the Chamonix valley. There is a chalet en route, which sells refreshments during the summer months. The main obstacles are a boulder field and a short ice field. Carrying an ice axe is recommended here in case of a slip, although I found crampons unnecessary. The top is likely to be snow-covered, even in summer, but one is rewarded by a splendid view of Mt. Blanc just across the valley, and of the Alps of Haute Savoie. |
The Mont Buet (3,096 m) is a mountain of the Chablais Alps in Haute-Savoie, France.
History
The first known attempt at ascending on Mont Buet was that of the Jean-André Deluc and his brother in 1765. After a second failed attempt, Deluc and his brother managed to reach the summit on September 25th, 1770. Here, they carried out a series of scientific measurements which was the initial purpose of their expedition.
Using a portable barometer designed by him, Deluc measured the air pressure on the summit. By comparing this result to a parallel measurement taken by his father in Geneva, and after correcting for temperature, Deluc inferred that Mont Buet was at an altitude of 2674 m above Lake Geneva, and 3040 m above sea level (2% less than the modern value).[2] Deluc also took advantage of the position and visibility of Mont Blanc from the summit of Mont Buet to determine its relative height, from which he derived that Mont Blanc was 4660 m above sea level. This was 400 m higher than the earlier trigonometric measurement of Mont Blanc by Nicolas Fatio de Duillier, and made the Mont Blanc the highest peak in Europe.[3]
Deluc reached the summit of Mont Buet from the side of Sixt by climbing directly through the cirque of Fonts. Because this route was considered to be too demanding, in 1775 the Genevan artist and travel writer Marc-Théodore Bourrit sought a different path from the southern side of Chamonix and Vallorcine.[4] This path follows along the valley of the Bérard to the refuge of the Pierre à Bérard.
In 1776, the Genevan geologist Horace Bénédict de Saussure followed the path discovered by Bourrit to reach the summit of Mont Buet.
