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 🙏
