We have backcountry skied various sections of the Wapta Traverse, high elevation glacier routes in the Canadian Rockies.    We have started from Peyto Lake, from Bow Lake, and from the Yoho Valley and skied over routes in all kinds of conditions, usually in late winter.    On one of these days, we skied in near-whiteout conditions from Balfour Hut to Bow Hut, passing under the vertical slopes of Nicholas Peak.    We found our way to the hut and then out, after various adventures, all longer stories.
