In reply to fultonville:
Mmmm. I'm sure it's all true, but on "Another day at the Office" a few years back my wife and I chipped our way neatly up in good order to hear, as we started faffing with the ab, a repetitive mighty thumping and crashing.
It continued. Then there was a lot of shouted instruction and more ice came thundering down. "It's going to be a swan ?" we teased (no originality, I know.)
We abseiled neatly down, past the CANADIAN GUIDE leading his client up the beatup-remains of what had been a very fine little two-pitch waterfall.
Clearly the Canuck competence at mighty acres of steep ice isn't ubiquitous. Maybe the best guides don't do Whistler piste-side cascades.
