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 🔬 Mer de Glace stone pine (300-500 CE) killed during the so-called 'Late Antique Little Ice Age' 🧊🥶

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) 🧊⏱️

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)! 💪 1/
