Glacial striae and roches moutonnées bordering the new glacial lakeFollowing 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. |  Rock, moraine and water - abstract art made by Mother Nature. |  Roche moutonnée with an open fracture (lower right) and bright quartz vein (left). |
