Route Notes Plan to break up into 2 to 3 teams aiming for various goals: "Mingbo Eiger" North Face, Peak 6430m N Face (N summit of Kangtega), Cholatse North Face. GEAN (Groupe Excellence d'Alpinisme National) of French Alpine Club, leader Stephane Benoist. BC on 08/10 at 3985m (Pangboche). Acclimatization Climbs: Meanwhile, the rest of the team with Thomas Arfi, Louis Pachoud, Gabriel Miloche and Anouk Felix-Faure climbed the normal route (SW Ridge) of Cholatse. 13/10: first climbing day. From 4000m, intended to make first bivouac on the glacier afoot of the col. Since they couldn't find a suitable place there (not being exposed to objective risks), the team climbed up instead directly to the col. Made a bivouac at 5600m, which happened difficult for acclimatization. 14/10: had a "small day" further up on the ridge until a 5800m bivouac. 15/10: made the round trip to the top, summiting between 1 and 2 pm. At first had been concerned by the weather, since last days' clouds were arriving at about noon. However on that day, they got clear sky conditions on the top. 16/10: from the 5800m bivouac down to Thare village (4350m). 17/10: back to BC. Primary Climbs: 22/10: Unclimbed Omoga Ri Chang (in JK, 6070m; not an opened peak, but permit had been taken for nearby Kangtega). NW Face to NW Ridge. "Mingbo Eiger" is the name of NE Face, which looks like Eiger's N Face in the Alps; it's been christened by the Brits who first remarked the face (ref Victor Saunders, Paul Ramsden?). Thomas Arfi, Gabriel Miloche and Louis Pachoud intended to climb the NW-orientated broad couloir located on the left side of the W Face, then to follow the NW Ridge to the top (previous solo attempt of Andy Parkin? in ?). From there the duet had planned to down-climb the SW Ridge to the col (with Kang Tari, 6071m), then down-climb the steep NW couloir below it. Known details about the attempt: 23/10: the trio reached the lower ABC (4600m). 24/10: the trio walked further up till the bottom of the face, sleeping at the higher ABC (circa 4900-5000m) located nearby the start of the route (right bank of the main couloir). 25/10: the trio took the whole day observing the face and its snow conditions from the higher ABC. 26/10: first climbing day. Started at 2 am, climbing all day. At 17:11, they sent a SMS via their satellite phone to the other team climbing on Cholatse: "All right, long day, bivouac at 5650m, great gully. Now it's time for the ridge. Kiss". This was to be their last communication. Rescue details: 30/10: Without any news of the trio since the 27th, an alert was launched by the trio following the climbers (weather forecast Nicolas Feraud, plus French climbers Damien Tomasi, Benjamin Guigonnet) to start a flying rescue operation, under the FFCAM aegis. 31/10: In the morning, a survey heli-flight of Kailash Adventure crew (pilot Claudio Mittner) could fly to the place. The team could first spot the higher ABC tent; then see at the bottom of the NW couloir 1 bag and an ice axe lying on the surface of a vast avalanche debris; then the pilot went up the face, noticing an interruption of the climbing footprints at some stage, then above it the 5650m bivouac place; further up, the team spotted the trio's footprints going up to 5900m as a high point, then back down (the team had obviously passed the steepest section of the ridge already). At 5900m, the team had triggered an avalanche (snow slab, cornice...) on the NE Face, choosing to go back down by the same way. FFCAM statement detailed that the helicopter had: "spotted the tracks of the ascent, as well as the debris of a vast avalanche which had swept the face". It also mentioned that: "it spotted the [higher ABC] tent and landed nearby it. Finding no one, it took off again to watch the face and follow the ascent's tracks. The latter stop on the summit ridge at an avalanche' break circa 40cm thick. Here the footprints go back down until a bivouac place where the 3 alpinists likely slept. The footprints go further downwards for about a 100m. Then it stops at a gully from which an avalanche apparently triggered. The pilot went back down at the bottom of the face to discover an avalanche cone with two bags, one mattress and ice axes”. 01/11: A Nepali rescue team involving Sonam Sherpa, Mingma Gyalje Sherpa, Vinayak J Malla, Ang Dawa Sherpa, Tshering Sherpa and Pemba Gyalzen Sherpa was helicoptered to try to find some potential survivors on the footstep of the face, but they found nothing except empty the aforementioned tents, bags and ice axes. The 5 remaining members of the GEAN expedition were helicoptered to the higher ABC, below the face, for a moment of silence. Then Stephane Benoist and Pierrick Giffard did a survey flight over the peak (with the same swiss pilot Claudio Mittner). It allowed to follow the footprints of the trio up to 5900m on the NW Ridge. At this place they saw the clear mark of the avalanche, as well as the footprints that the trio had left when turning back down. Circa 50m below the 5650m bivouac, they found a yellow snow stack, confirming that the trio had begun its descent. 30m below the same snow stack, at circa 5570m, they lost any signs of the trio, noticing that the snow here had disappeared for an ice slope instead – obviously the place from which the trio had fell to its death. The exact cause of the trio's fatal fall remains unclear: proper fall; snow slide coming from above; snow slab triggered at the 5570m place? The remnants of the upper and lower ABC were evacuated on this day. 02/11: the team stayed in Pangboche, packing his gear. 03/11: team flew from Pangboche to Kathmandu by helicopter. 05/11: a French rescue team comprising experts of PGHM and former GEAN coach Christophe Moulin flew from Geneva to Nepal. 07/11: the Nepali rescue team located the 3 bodies in the remnants of the avalanche, afoot of the face at circa 4900m under 1m of snow upstream and 0.5m downstream. On this afternoon, French Guy le Neve and Christophe Moulin reached the area. 08/11: the 3 bodies were taken out from the avalanche on this day. The French rescue team begun to analyze the gear remnants and tie-in to understand the circumstances of the accident, an effort which would continue on the next day. 10/11: the French rescue team made a reconstitution of the accident in its lodge at Namche. 11/11: the French rescue team left Nepal.
