"A mica schist outcrop polished and striated by the passage of quaternary glaciers, the last great ice age gœs back more than 10,000 years. The glaciers descended to Lyon at that time, and ice over 1,000 m in thickness filled the great valleys (Grenoble). The English call these “roches moutonnées” whalebacks. The inhabitants of Champagny-en-Vanoise call this rock ""Dos de l´éléphant” (the elephant’s back)."
