View across Tour Glacier towards Aiguille Verte and Mont Blanc today! 😍 Very little snow for early June... 🥵 📷 @lomdumtblanc.bsky.social

Jonction!

Glacier des Bossons towered by 4,000ers (Mont Blanc du Tacul, 4,248 m and Mont Maudit, 4465 m) as seen from La Jonction today! 🏔️🧊🥰 Most icy landscape of the rest of your life... 🔥 📷 by @lomdumtblanc.bsky.social 🙏

Young Pinus cembra recently damaged by an avalanche against the backdrop of a glacier entirely damaged by human activity! 🧊🔥 Bossons Glacier today 🤍 📷 by @lomdumtblanc.bsky.social 🙏

Bossons Glacier 2022 | 2026 📷 @lomdumtblanc.bsky.social & Guillem Lafitte

Large subfossil log sampled in the Trient Glacier lateral moraine last year and just tree ring dated to the 1285/86 CE winter! 🧊🌲💍 Means that the Medieval early-LIA advance has reached the level of late-LIA (eg 19th c.) as we already show elsewhere in the Alps (journals.sagepub.com/doi/full/10....)

Melting glaciers today in Chamonix! 🧊💧💦 We just out fom the longest May period with average temperature >2°C (5 days) at Aiguille du Midi (3842 m asl), a threshold for cryospheric change at high elevation glaciers! 🏔️🔥 Picture: @lomdumtblanc.bsky.social Data: Xavier Cailhol

The year before the hole appeared in Bossons (here 10th Sept 2022), it still retained its incredible and endless tongue spreading across the valley! 😍 A vision that gave me goosebumps every time! 🤍 Now lost forever. We are losing beauty, in addition to our ability to live on this planet

Argentière serac ice cliff gazes huge recent ice loss! 🧊🔥 Thinking that back in 2009, both parts of the glacier were still connected! Now the serac no longer feeds the lower body, which sags at an incredible speed! A monumental natural amphitheatre, soon entirely de-icing because of us 🤮

Fieldwork in Argentière gorge is always stressful 😬 So many things can turn bad... -Rockfalls -precariously crossing streams tens times/day -AND sudden releases of water (Emosson SA) that can make the torrent impassable (don't be on the wrong side :) A bit of mental strain, but LOVE this place 🤍

Y'all notice that gaping hole first appeared in Bossons icefall in late summer 2023! 🧊🔥 Only the right branch (which won't last summer) still connects with the dead and flat lower body 🌡️ At most, it is still feeding by some seracs fall, but for how long? ⏳ @lomdumtblanc.bsky.social yesterday 🙏

So much change in one year! 😱 (Bossons glacier)

There's still so much snow!

Another unseasonal 'summer' day with freezing level above 4100 m asl, i.e. just below Dôme du Goûter (4,304 m) here ! 🥵

What's left of lower Argentière Glacier... 🧊🔥 Both parts were still connected in 2009!

Trient Glacier from the Little Ice Age lateral moraine today ! Huge retreat of this glacier tongue... 🧊🔥

23°C at 9 am in Chamonix... 🥵 Everything is fine (nope) 😱

Aiguilles de Chamonix tonight ! 🤩

Mont Blanc last sunday! Enjoy this 'snowy' view, as isotherm 0°C will rise at 4,200 m asl from friday! 🔥 This meagre snowfall does little to make up for the drought of a barren winter on the glaciers Summer looks set to be relentless once again... 😱 📷 @lomdumtblanc.bsky.social

Bright morning over Mont Blanc today after days of unstable weather! ❄️ View towards Taconnaz Glacier towered by Dôme du Gouter (4,304 m) 🏔 📷 by @lomdumtblanc.bsky.social

Even fresh May snow cannot hide the irreversible damage caused to the Bossons Glacier by human-induced global warming! ❄️🧊🔥 📷 by @lomdumtblanc.bsky.social

Microplastics on top of Mont Blanc (4,806 m asl)! 🏔❄️🚮 Discover the full report here: hal.science/hal-05426589...

I revere erratic boulders. Torn from their bed, carried away and left in a place they did not choose. They bear witness. We listen to them if we can. We located this one yesterday, deposited at least 200 years ago at Mer de Glace Literally perched in a cliff Pure joy!

Wildfire in Chamonix valley today! 🔥😱 In Les Houches (Montagne des Faux, 1300 m asl)

Les Drus topping the 200 m-high Mer de Glace lateral moraine 🏔 So dry for the season that it is stable ! 😎 Usually, I never do fieldwork there so early (boulders bombing!), but didn't see anything fall today...

18th annual subfossil wood sampling campaign today at Mer de Glace! 🌲💍 Never did it so early in the season, feels like late june, so dry! 🥵

The modesty of the great ones! 🏔

How dry are high elevations in the Alps? ❄️💧 Insanely dry... 🥵 See the Périades Glacier, between Mont Mallet (3,989 m) and Dent du Géant (4.013 m), with ice already visible everywhere in steep slopes above 3,500 m asl... 😱

Dôme du Goûter (4,304 m asl) taking first rays this morning! 😍 Taconnaz Glacier just below 🧊

Mont Blanc du Tacul (4,248 m asl) and Mont Maudit (4,465 m) topping disfigured Bossons Glacier this morning! 🏔🧊

Les Droites (4,000 m), Aiguille Verte (4,121 m) and Drus (3,754 m) this morning! 😍

Les Aiguilles de Chamonix from Col des Montets today! 🤩

Sunset on Bossons Glacier from its left lateral moraine today! 🧊 Feels like summer... 🤪

Mont Blanc and Bossons Glacier tonight! 🥰

Sunset on Aiguille du Midi tonight! 😍

Against the light on Verte and Drus this morning highlighting the size of the Nant Blanc moraine complex! 🤩

Nothing can beat Mont Blanc on a 'jour blanc'! 😍 Makes the ice more present and magnetic! 🧊

Bedrock is already outcropping in La Niche des Drus... in April! ❄️ 23°C in Chamonix at 6:00 pm, insane. 🥵

To look at Bossons head-on is to face up to our collective responsibilities! Lateral branches have now detached from lower body, and situation will be catastrophic by the end of next summer! Retreat will accelerate further, leaving behind only memories of the most beautiful glacier in the Alps!

Mont Blanc massif from Aiguilles Rouges today! 🤩 📷 @lomdumtblanc.bsky.social

I sampled this profile (dark brown, left) on top of the lateral moraine of Argentiere Glacier 15 yrs ago! It basically no longer exists today, bedrock is outcropping everywhere! These moraines won't be around much longer!

Argentière Glacier ice cliff today! 🧊 The regenerated body below is now barely fed and has thinned a lot 🔥

Large and recurrent instabilities (along the lengthy dark band) between Bossons (L) and Taconnaz Glacier (R) tongue, west of La Jonction 🧊 ❄️ 🌊 Last night rockfalls were incessant... 🔥 Started few years ago, but intensified since this winter! Any feedback from the field?

Mont Blanc massif this morning from around Lac Blanc! 🤩 📷 @lomdumtblanc.bsky.social

Dômes de Miage (3,673 m asl) today! 🤩

Mont Blanc (4,806 m asl) and Bossons Glacier today! 🤩

Mont Blanc (4,806 m) and Dôme de Miage (3,673 m) this afternoon 😍 Not much snow for the season... ❄️🔥 For weeks now, the temperatures have been typical of June! 🥵 Do you find that pleasant? The Earth doesn't. 📷 @lomdumtblanc.bsky.social

Aiguille Verte and Drus today! 🤩

A summit blasted and drilled... For the dreams of star architects An “eco-friendly” reconstruction (they say) 🤬😭 ... 2/
