The Lac du Génépy and its moraine

If you think you will discover a clear expanse of water when you arrive at the lake, you will be surprised. The Lac du Génépy is a glacial lake. At the end of the little ice age (1550-1850) the Labby glacier left a moraine on the right bank of the lake. A moraine is an accumulation of stones transported along the front of the glacier and left in place during its retreat. The glacier gouges out the rock in front of the moraine. The glacial meltwater occurs in this basin, creating the Lac du Génépy. The very fine mineral particles that you can touch on the shores of the lake fill it gradually and give it its milky colour.
