Three years ago, I spend some days on the Swiss Alps. All the glaciers we visited were in clear recession. Ok, this is a global issue. But I was suprised by a little detail in the Ferpècle Glacier, in the Évolène valley, near Sion, Switzerland. There were several trees on the river bed, just below the ice edge. A clearly retreating ice edge, one has to say. On the first photo, you'll see the remains of the tree on the river bed. The second photo show a general view from a recent morraine. You'll see the same hole on the glacier from which melt waters flow in its context. The area is at 2000m above sea level and you'll see no trees. Can anyone explain where these trees came from? I say trees because there were several of them, and we could even see one inside the glacier.
