Diablerets
Diablerets, a mountain group of Switzerland, situate in the Bernese Alps, between the cantons of Vaud and Valais. The highest point is 10,620 feet. There is much clay in the formation, and the result of glacier action upon this is to cause frequent and considerable landslips, the most considerable of which have been those of 1714 and 1749. In the case of the latter of these, the Liserne was choked, and its waters formed the small lake of Derborence.
