Chablais Alps in the context of "Mont Blanc Massif"

The Bernese Alps are a mountain range of the Alps located in western Switzerland. Although the name suggests that they are located in the Berner Oberland region of the canton of Bern, portions of the Bernese Alps are in the adjacent cantons of Valais, Fribourg and Vaud, the latter being usually named Fribourg Alps and Vaud Alps respectively. The highest mountain in the range, the Finsteraarhorn, is also the highest point in the canton of Bern.

The Rhône valley separates them from the Chablais Alps in the west and from the Pennine Alps in the south; the upper Rhône valley separates them from the Lepontine Alps to the southeast; the Grimsel Pass and the Aare valley separates them from the Uri Alps in the east, and from the Emmental Alps in the north; their northwestern edge is not well defined, describing a line roughly from Lake Geneva to Lake Thun. The Bernese Alps are drained by the river Aare and its tributary the Saane in the north, the Rhône in the south, and the Reuss in the east.

The Lac de Montriond (Lake of Montriond) is a lake in the Chablais Alps at Montriond in the Haute-Savoie department of France. It has a surface area of 32 hectares (79 acres).

There is a circular path around the lake and several restaurants next to the D228 access road (which connects Montriond to Les Lindarets). In winter the lake surface frequently freezes over and the immediate area surrounding the lake experiences extremes of cold due to the topology of the surrounding area blocking most sunlight during the coldest months of winter.
