did this April 27th 2009, from Aigille diu Midi mid station to Grand Mulets (bewere the dangerous “Junction” section of crevasses and bridges to be negotiated on the way to the hut)
Grand Mullets hut was fully operational. Book ahead. Breakfast is served about 1am and you set off by 2am. Make sure you get out of the hut before everyone else as there will be a big Q (the hut is perched 30m above the glacier and it is pretty epic simply getting down to your skis) We took your red route up and green route down, as did the other 50 or so people in front of us. You cannot ski all the way up the ridge, it is a bootpack with crampons and ice axe. Beweare getting very cold at transition from skis to crampons at 3am (- stupid degC). We roped up as it very exposed. Ice axe v. useful for negotiating scary exposed crevasse/crack about halfway up ridge, (about 5am as it was getting light i think). I do not think that descending this route would be a good option, not on skis anyhow.
Green route down: Stick to the tracks so long as they do not dissapear into big holes. Huge crevasses to the left and right hand side. Don,t stop to look at the view, enormous amounts of serac fall debris (ranging from size of large houses down to golf ball sized) , very scary, some open crevasses to hop over, keep skiing. This was probabaly the most scary ski i’ve done, although technically easy at least.
Overall, technically the skiing and climbing is not particularly difficult, but not to be underestimated; good fitness, rope-work, crevasse negotiating technique, rescue, crampon & ice axe use, navigation, route choice, etc. skills are all required. If you not having them a UIAGM Guide is essential. Numerous large dangers everywhere. Keep an eye on the weather, we got clouded in at the Vallot hut and were exceptionally lucky that the cloud cleared for 5 mins and we managed to find our way down. Otherwise we were in for a night at 4000m, and we did not really have enough warm kit, so that could have been disastrous.
After decending to the Hut the fun is not over as you still have to re-negotiate the Junction area below the hut. This time it is late in the day and so more dangerous, plus very tired. Worked out way back and across and up (very tiring traverse and climb under exposed late-in-the-day cliffs, a little like one of those 1980,s computer games where you dodge the deadly flying stuff coming out of the top of the screen) to ADM mid station by about 5pm, making for a 15hr day.
We wree in the bar in Chamonix by 6pm and all was well. Thanks Doug , Hamish and Rich for that!
Overall, best mountain day of my life, but we were a little lucky on a couple of occasions...
