Glacial striae and roches moutonnées bordering the new glacial lake
Following the recession of Rhonegletscher, a riegel emerged from under the ice which now displays remarkable examples of glacial erosion.
General view of the newly emerged roches moutonnées, looking towards the Rhône valley.
Compact granitic bedrock was highly polished by the scouring action of ice and debris.
Limonite deposits formed in cavities facing downglacier.
Striae emerging from the lake show how the ice moved up and over this roche moutonnée.
Highly polished rock reflects the sunlight as if it were a mirror.
This small erratic was deposited on the top of a massive roche moutonnée.
