Glaciers are supposed to be pristine white, but as these ones descend from the mountains they collect scree rocks and end up covered in grey boulders – you can see the glacial face at the end of the melt lake.  We walked up here in the evening, the landscape was desolate and not at all comfortable, only rock, water and mountains.

The sides of the lake are the lateral moraines left over by the melting glacier.  The highest level seen on the mountains at the back date back from the 1300’s: the glacier has been slowly melting since then, way before global warming was fashionable.
