It's a Cham

I've just discovered this nice little website, which provides a really cool and well-designed guide to Chamonix: -

Whether this information is accurate, I will better equipped to tell you in March, when I'm heading out to the Valley for a week-long winter alpine and ice climbing course with top UK outfitter Icicle Mountaineering (http://www.icicle-mountaineering.ltd.uk/).

Bring it on!
