General

The routes here are organised after the summit they lead to. Routes of the same mountain are sorted by the difficulty grade. Note that difficulty grades do differ, as grading is always somewhat subjective. Grading of some routes do differ considerably between different guide books. The difference may be as great as a whole alpine grade. Thus there is no guarantee, that grades shown here are accurate.

Grading system used in Griffin's guidebooks is different than the one used by Eberlein in the extreme end. Eberlein uses ED-, ED, ED+, ABO- and ABO to refine grading of the extreme routes. Griffin however has adopted free-ending numerical scale to classify such routes.

Route introductions consist of several parts:

Name and alpine grade

[references]

  • First ascent information
  • character (ice, snow, rock, mixed), predominant difficulties (alternate grading systems), other difficulties
  • Height from the begin of the actual route (unless otherwise stated), lentgh and time
  • Description consisting of information such as best time and/or conditions, danger/commitment, another notions.

Conditions can greatly affect the difficulty, seriousness and time of a route. It has to be considered, that especially ice routes may be a fair bit harder to climb and almost impossible to protect when ice cover is thinner (especially late summer). Blank ice conditions also make climbing ice routes much more strenous. Also general melting of glaciers and possible large rock falls can dramatically change the route over the years.

Mont Blanc 4807 m

  • Mont Blanc is often referred as the highest mountain in Europe. This is not true, as Elbrus, located in Caucasus, is by far higher. However, Mont Blanc is clearly the highest mountain in the Alps.
  • Horace-Bénédict de Saussure, scientist from Geneva, started the competition over Mont Blanc by promising a monetary reward of 20 thalers to the first ascender.
  • First succesfull ascent was made on 8 August 1786 by Michel-Gabriel Paccard (Doctor from Chamonix) and Jaques Balmat (crystal hunter). They found their way up the Rochers Rouges and the North-East slope (biwouak in the Colla della Brenva).
  • Saussure himself was guided to the top in 1787.
  • Marie Paradis was the first female to reach the summit (1808).
  • First winter ascent by I. Straton, J. Charlet & S. Coutett on january 31st 1876.
  • Currently there is over 100 routes leading to the top of Mont Blanc.

  • II on the rock rib pitches, 40° on the Bosses Ridge.
  • From Nid d'Aigle to Tête Rousse 800m, 2-3h and further to Goûter Hut 700m, 2-3h. Summit climb from Goûter Hut 1050m, 4-5 .
  • Stone fall danger, especially if crossing the couloir to ascend on the south side rock rib above Tête Rousse Hut (easier), only few crevasses. Most frequently used ascent route.

Grands Mulets PD

[Eberlein #182; Goedeke s.212; Griffin 1#58]

  • First ascent 29.7.1859 by E.Headland, G.Hodgkinson, C.Hodson, G.Joan, F.Couttet & two other guides.
  • Twice as long as Gouter Ridge, only normal clacier travel with crevasses. From téléphérique station Plan de l'Aiguille (2310m) to the Grands Mulets Hut 800m, 3h, from there 1776m and 6-7h to the summit. Occasiobnally plenty of crevasses, route finding problematic in bad weather. Less exposed to wind than Goûter Ridge, thus safest descent route on the bad weather. Popular ski mountaineering route. Starting point: Grands Mulets Hut.

Aiguilles Grises (Italian normal route) PD/PD+

[Eberlein #252; Goedeke s.212; Griffin 1#63; Rebuffat #30]

  • First ascent in 1890 by L. & J.Bonin and Achille Ratti (later Pope Pius XI) with J.Gadin and A.Proment.
  • Two variations:
    1. Glacier Variation PD+, 40°
    2. Non Glacier Variation PD, mixed up to II
  • From Lac Combal in the Val Veni 1050m, 4h to the Gonella Hut, from there 1736m (7-8h) to the summit.
  • Normal Route from Italy. The route of choice fro those looking for solitude and a beautiful unspoiled scenery. More technical than Goûter Ridge, and one should not under estimate the fact that evrything on the Italian side of Mont Blanc is far away - this is definately a much more commiting route than normal routes on the French side. Disrupted glacier that can be barely passable during late summer.

Three Mont Blanc -route PD+

[Eberlein #188; Goedeke s.198&201; Griffin 1#62]

  • First ascent 13.8.1863 by R:Head, J.Grange, A:Orset & J.Perrot.
  • snow and ice, 50°
  • Glacier climb with steep snow up to 50°. Bergshrunds on the northern side (especially on the Mont Maudit) can be difficult to pass during (late) summer. Avalance danger on North Face of Mont Maudit and North-West face od Mont Blanc du Tacul after new snow. Route finding can be problematic (compass does not work reliably close to Mont Maudit). Starting Point: Cosmique Hut on Col du Midi. Possibilities to summit Mt Blanc du Tacul & Mt Maudit.

The Face lies in the shadow, so it is cold, which renders it safe against stone fall. Not recommended during windy or unsettled weather, as the route is heavily exposed to the wind. Not suitable for descend.

  • First ascent 30.-31.7.1927 by L.Obersteiner & K.Schneirer.
  • Sustained rock climbing at III and II with passages of IV, mixed, seldom easy, snow or ice up to 55°. Principal difficulty is however the length and sustained and changing demands.
  • Requires well settled weather. Remote. Everything that can possibly be encountered on high mountains: crevasses on a very disrupted glaciers (especially on retreat); stone-fall in the couloir to the Brèche Nord des Dames Anglaises, especially in good condiotions; loose rock on the rib on the South-East Face; hypothermia on the summit ridge in storm; avalanches on the Rochers Gruber in bad weather, etc. Principal danger is the bad weather forcing a retreat. This will be either a down the Rochers Gruber or difficult ascent to the Col de l'Innominata. Starting Point: Monzino Hut.

[Eberlein #224; Griffin 1#91; Rebuffat #100]

  • Frêney Pillar was regarded as the last of great problems in the Alps. Bad weather forced legendary Walter Bonatti and Pierre Mazeaud to cancel their pursuit in 1961. A few weeks later (27.-29.8.1961) Chris Bonington , I.Clough, J.Djuglosz & D.Whillans succeeded to make first ascent. First winter ascent 1.-6.2.1967 by R.Desmaison & R.Flematti.

    • First ascent is unknown as altough Whympers team based their route around Whymper Couloir, they traverse out of the couloir itself at around one third of the height. First descent 17.9.1865 by R.Fowler, M.Balmat & M.Ducroz.
    • 55°, avg.48°
    • Hut climb from Montenvers 900 m, 3-4 h. Summit climb 1450 m, 6-9 h from the hut.
    • Large scale snow and ice route that is best climbed during early summer, when climbers profit greatly from generous snow cover. When this is not present, ice climbing may be very hard at bergschrund (on descent this is often problematic involving a big jump or awkward abseiling). Starting point: Couvercle Hut.

                              • Starting from Torino Hut (3375m) cross the Col des Flambeaux and go around the base of Aiguille de Toule. From there there are two possibilities: a) follow the glacier on the east side of Tour Ronde to the Col d'Entrèves (3527m, 1,5h from the hut). Follow the snowy South-East ridge, at first on the right side, then turn a series of gendarmes on the left. Reach a snow saddle of Col Freshfield at 3625m. b) Before reaching the Col d'Entrèves head right to relatively steep (max.45 degrees?) snow couloir. Pass the bersgschrund and climb the couloir directly up to Col Freshfield . From Col Freshfield climb on a moderate rock (II) with some airy sections on the granite crest. This is followed by a snowy slope that leads on the foot of final rocks. Scramble them to achieve to summit. In descent 2-3h from summit to Col du Géant. It is possible to rappel the steep rocks down to Col Freshfield.

                              • A challenging route with 10-12 pitches of continuous ice up to 60 degrees. An established ice climbing classic providing good introduction to steeper alpine faces. The Face narrows to an icy couloir in the middle section (crux) then opening up again on the final broad and exposed upper slopes. Very popular, so an easy start is to be recommended to minimize rockfall (the route gets morning sun) and to be ahead of other parties. By keeping on the right side of the slope, it is possible to obtain good rock belays for the most of the route. Staring point: Torino Hut.
