Aiguille de Triolet - a mountain of the Mont Blanc Massif
    The Aiguille de Triolet belongs to the Mont Blanc massif. It's placed in the eastern part of it, and also it's point of union of 4 ridges that divide as many basins. On the north side (France), from the summit starts a ridge that includes the famous Les Courtes, Les Droites,Aiguille Verte and divides the basins Argentière (north) and Talèfre (west) with their ominous glaciers. On the south side (Italy), a minor ridge called Mont rouge de Triolet, divides the basins Pré de Bar (east) and Triolet (south). Both covered by glaciers, but smaller if compared with the northern neighbours. The boundary ridge between Italy and France where the Aiguille de Triolet is placed, includes also important summits (from east to west) as Mont Dolent, Aiguille de Talèfre, Aiguille de Leschaux and Grandes Jorasses. The west flank is almost totally covered of ice and it's also easily climbed by ski. The other 3 flanks are made of good yellowish granite, first of all the spectacular north wall above the Argentière Glacier, which has made this mountain famous in the alpinism history.
Historical note:
    The first climbers of the Aiguille de Triolet were J. A. G. Marshall, U. Almer and J. Fischer on 26. August 1874.

    During a long time, the classic north face route of 1931 was important. It has been considered as the most difficult ice climb in the Alps. Even today, it's a route where ice climbers can increase their reputation. The other routes are seldom climbed. This classic route from 1931 was done by R. Gréloz and A. Rochs, technically very gifted climbers from Geneva. At that time, the main problem of the face was the ice conditions; this is a problem which has lessened over the years from the first ascent. Of course, on any snow and ice route, success always depends on the quality of the snow; nevertheless, these days, with the technical advances made possible by front-point crampons and by ice pitons and screws which allow good belays and abseils (both of which were impossible earlier on), it is possible to undertake this climb even if optimum conditions do not prevail everywhere on the face. It is this, as well as the face's intrinsic beauty, which explains why there are a number of ascents every year.

    As is the case for any glacier face, the north face of the Triolet changes year by year. The snow, annually accumulating above and slowly compressed to form ice, moves downwards, adds weight to and extends the rows of seracs. The slope is very steep, 53° at the bottom and even steeper in the middle. The angle towards the top depends on the route taken; you can go straight up as did A.Contamine and L.Lachenal, but normally you traverse right above the big serrac barrier and then either come back left to get to the summit or exit directly onto the ridge of the Petites Aiguilles du Triolet.

    Getting There

    To the Aiguille de Triolet
      You can come from the Refuge d'Argentière. You can come from the Refuge du Couvercle. You can come from the Bivouac Fiorio. You can come from the Refugio Dalmazzi.
    To the Refuge d'Argentière
      In order to reach the hut, you have 3 possibilities: From Croix de Lognan (1970 m) in 3 - 3,5 h, to Croix de Lognan with cable car from Argentière. From Croix de Lognan, you go on foot up over the morainecrest till about 2250m. Than you continue horizontally to the glacier, which you follow on the orographically left side. After about 1 km, the glacier becomes steeper and more torn. You climb onto the morain of the Rognons, first over a slippery shelf, than via a marked way which you follow until you reach the upper end of the ice break. You climb the glacier in SE direction and reach over the moraine the hut. On foot from Argentière in 5 h: From the ground station of the cable car, you follow the wide aisle of the ski-run. You leave it at the height of about 1750m and reach the way of the middle station of the cable car (2 h). Now, you need 3 h to the hut. From Aiguille des Grands Montets (summit station of the cable car from Argentière; last train up: 4:45 p.m.) in 2 h. From the summit station, you go via a stairway to the Col des Grandes Montets. You traverse a bergschrund (maybe with the help of a rope) and go up the steep hang to the Glacier Rognons. You go with ENE direction on the western side along P. 3000 to P. 2754m. You go down southeastern to the glacier d'Argentière, which you reach above the icebreak. From here in 2 h to the hut. You reach Argentière by train (from Martigny/CH or Geneva or Annecy - TGV to St. Gervais), bus (from Annecy, Geneva, Grenoble, Courmayeur, Aoste and Turin) or car from Geneva or Martigny (Switzerland) via Vallorcine and the Col des Montets.
    To the Refuge du Couvercle
      You reach the hut from Montenvers in 3,5 h over the glacier. From Montenvers to the starting point of the hiking way to the Refuge d'Envers des Aiguilles. You have to follow the way with direction to Les Echelles which goes slightly down to the western side of the Mer de Glace. But before you enter the Glacier, you have to follow the way on the western side of the glacier for about 20 min. Now you have to go up the glacier first more on the western side, then just through the middle with SE direction to Les Moulins. Now you do not follow the marking signs to the moraines but continue with S and then E direction to the steep passages at Les Egralets (partly a little bit like a way). You go the steep passages up and via a good way through grass hangs to a moraine, from which you reach the hut soon. You can reach the hut via a new climbing track below the Flammes de Pierre and the ends of the Aig. du Moine to the Ref. du Couvercle. But because of ice avalanches, some passages of this route have become very dangerous. You have to ask for the actual conditions. 3,5 h from Montenvers to Couvercle.
