How much longer will we be able to enjoy being close to the ice? 🧊
These sensations are essential, yet have become so rare... 😢

The dead ice lowest point is ~1650 m and the ice cliff at the background - which hardly feeds it anymore - is ~2200 m asl 😨

A clear path! 🤩
When the wood is full of resin and sticky, sanding doesn't allow the tree rings to be seen clearly enough 🧐
It is then necessary to make a path with a razor blade filled with chalk 🔬

It dates the Bronze Age Advance Period of this glacier to 1553+ BCE, which is conform to other calendar dates we have in the Alps at ~1550-1540 BCE (Mer de Glace and Gepatsch) 🧊⏱️
