I just got back from Chamonix France to do Mt Blanc the grand Mulet route. unfortunalty we had a small window of weather and missed our chance to get up to hut by one day,., and possibly summit by about 3 days.. France is a very frustrating area to gather accurate information. When we first got there to chamonix we went to the usual places to get beta on current conditions... they moutain rescue people spoke hardly any english and basically told us not to go up there,. the moutain guides were no better,.. so we hung out by the aquille du midi the cable car to get to the approach were we met some guys from scottland who just came down they were happy to talk to us and said they did summit..they had to break trail 10 hours from cable car to hut ( book says 3-5) and 12 hours from hut to summit these were really longs times as they had to go really slow to break trail and watch out fro crevases due to lack of previous snow. we attempted to get up to the hut the very next day .,. packs on skis in hand in hopes of riding out the upcoming storm at the grand mulet hut we got to the cable car and they basically said there was no visibility...what does that mean we asked we want to go to the hut not sight see,.,. once again no visibility .. we sat there and watched them turn away tourist after skiier after tourist not taking there money and telling them to go across the street and not willing to send up a cable car for only 2 people willing to check it out.... no such luck .. our window had closed the storm set in and we were bummed .. even though we both knew this was a possibility given the time of year we went.... but it is possible.... you can pm with more questions about the area ... we did find ice ... on the mer du glace glacer only to be turned around by very unstable conditions you could see the rock fall and hear it all up and down glacier ... but to save the trip since it did keep snowing and snowing we did go skiing at the grand monte area ... in waist deep powder best snow of the year said the locals....
