I just tree ring dated this large stone pine cookie sampled in 2024 below the Argentière Glacier lateral moraine 🌲💍

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) 🧊⏱️

Ski lift operators are commiting what amounts to environmental crimes! 🤬

Since 2024, SATA which operates Deux Alpes ski area has levelled Mont De Lans Glacier and filled in a 2000 m² new glacial lake that had appeared around 2010... without any authorisation!

UTTERLY SURREAL LOW ANGLE GLACIER SLIDE!! 😮😱

On Saturday at 11:00 am, a 2 km-long, 25 m-high, and 150-200 m in width section detached off the Ismoil Somoni Glacier (Tajikistan) and slid down the gorge! 🧊🌊

This is the only tree I found embedded in a moraine that shows a pre-existing cut mark! 🤔🌲⛏️

This means that this tree was felled by people and then (shortly afterwards?) buried by the glacier during a major advance (LIA)! 🧊🌊

Obviously, this can only happen in the Chamonix Valley (Bossons here)! ⛪

What trees can tell ? 🌲💍🥰

This small cembran pine found in the Argentière Glacier lateral moraine has likely grew in a steep slope (avalanche couloir) and had a perturbated life, struggling to maintain apical growth (orange compression wood, R)! 💪

Tré-la-Tête Glacier
1990s | 2025

Demise of the most 'secret' (fact already emphasised by Whymper in 1909!) large glacier of the Mont Blanc massif! 🏔️ 🧊

The icefall no longer exists and most of the left tributaries have broken off! 🔥

Imagine Tré-la-Tête Gacier in the 'Swinging Thirties' when first glaciological work began there! 🧊⏳⛏️

So moving to see these beautifully dressed early glaciologists! 🎩

Want to acquire such a priceless piece of our natural heritage? 🥰

This is a subfossil spruce from late Roman period that comes from Bossons Glacier in Chamonix! 🌲⌛

What makes it special? 💚
- Spruce is pretty rare in moraines
- Precisely dated to early summer 253 CE!
