yo,  Have you ever skied the big couloir in the summer?  Planning a trip for this year if you have any suggessions on what month it would be best(all depends on the thaw),  routes,  and skiablity(too steep?(google earth says 72% at the top?))?  Great Pics,  Looks spectacular.

While I have never had the balls or the ability to ski 3- 3.5 couloir (from the photo i am guessing that its not 3.5-4 ) , I used to ascend this as a quick entry to the Neil Colgan hut . The snow is best around July 20 th . After that the steepest pitch becomes ice . I figured it to be 60 to 65 degrees . Crampons and 2 axes are what I used for the ascents  . A classic  long axe and a short "throw away" or " 3rd tool "  axe . ITS A SHOOTING GALLERY in the summer . The freeze thaw cyle breaks out the limestone and 10 kg projectile whizz down the slope . We used to start at the foot of the couloir at first light 4am so that we could ascend safely before the projectiles started rainning down .There has been more than one death here . It has been skied before though one skier was seriously injured in a fall on his descent . Good luck and stay safe .

That bootpack photo is in fact the 3-3.5 couloir, the beautiful couloir that graced our old $20 bill and can be seen right from the parking lot of Moraine lake. I've skied it twice, the first time in June when it was quite crusty and scary and the second time in April when the road was closed, we had the whole thing top to bottom in boot top powder, it was epic! I would recomend hitting this line as soon as the road opens in May for easier access and the best snow conditions, or time it a day or 2 after a June storm. It is a very wide couloir with a massive convex roll off the top into the super steepness of it, so beware of slab conditions!

wow great photos
