Since the last update the snow conditions have changed as a result of the warm period linked to the foehn wind on Sunday. The snow quality remains inconsistent.
In the Aiguilles Rouges, the Col des Dards and the Col du Belvédère are popular. The return to Flégère is awkward due to lack of snow.
The Crochues-Bérard traverse is also being skied, with the descent of the Berard valley just about OK.
The Buet has been skied, (no further information.)
There has been activity at Loriaz where the Col de la Terrasse and the Bosse are tracked, (some rocks exposed at Les Charmoz.) The Veudale is also tracked but not the Tré les Eaux valley. The snow is generally well packed and OK to ski.
Snow conditions are more variable in the Pormenaz area with a lack of snow by the Souay torrent.
In the Argentière sector the Col du Tour Noir and the Col d’Argentière continue to be skied, though the return to Lognan remains complicated.
The Col du Passon is tracked but the conditions are not very good.
Concerning the “high mountain” activity, the gullies remain very dry, especially at the head of the Argentière glacier.
The Claire Chazal has been climbed albeit in very thin conditions.
The Couturier has (foot) tracks on the true left side; technically harder than usual. A lot of snow on the descent by the Whymper.
No information from the “heart” of the massive, except for the Cosmiques Ridge.
The Valley Blanche, though possible, remains complicated and only suitable for very good skiers/alpinists with glacier travel skills.
Many of the icefalls are in condition.
At Trient “Une colonne de glace peut en cacher une autre” and “Cascade difficile” have been reported to be in good condition. The approach is quicker on skis.
In the Argentière sector conditions were good on 19/01 at the true right bank, e.g. “Lolly Pop”, “Enzo”, “Les Jumeaux”, “Icelander” and “Grand Bleu”. Careful though as conditions can change rapidly, especially with the re-warming on Sunday. The true left bank has less ice. However, many of the routes are OK, especially in the “beginners” areas.
Though the Bellevue icefall at Les Houches has been climbed recently, it is now no longer in condition.
At Cogne the long cold spell has created good conditions. See the Hotel La Barme website: http://www.iceclimbingcogne.com/
Snow shoeing is possible at altitude: for example, the Prarion plateau, the Samoteux area, the Chalets de Chailloux at Les Houches, the climb up to Loriaz and Granges loop near the Buet village. The Aiguillette des Posettes is also possible, starting from the top of the Vallorcine lift.
The trails at the valley floor are lacking in snow but can be hiked with good boots and a pair of poles.
