The Mont Buet is a mountain of the Chablais Alps in Haute-Savoie, France. Mont Buet has played an important role in the history of science at the end of the eighteenth century when a series of Genevan scientists such as Jean-André Deluc, Horace Bénédict de Saussure or Marc-Auguste Pictet climbed to the summit to carry out scientific observations. Before the first successful ascents on the Mont Blanc in 1786, Mont Buet was "the highest among those accessible in this area" of the Alps.
