FALL THROUGH CORNICE, OFF ROUTE, UNROPED
Alberta, Banff National Park, Mount Balfour
On April 12, N.F., a ski patroller from Whistler and member of the ACC Whistler section, was skiing the Wapta Icefield traverse with two companions, D.S. and G.M. They were equipped with a copy of Murray Toft’s Wapta Traverse composite topo map and compasses. They had conversed with guides at one of the huts who had informed them that the snowpack was large this year. The visibility over the previous few days had been intermittent with some whiteout conditions. They had had no trouble with crevasses on the traverse. When they reached the Balfour Hut, they were joined by another party of two, S.F. and E.N., who were equipped with a GPS, compasses and an emergency radio. The two groups decided to combine forces on the ascent over the Balfour High Col to the Scott Duncan Hut.
They were skiing roped up in two teams. The skiers were using a Rutschblock cord tied to their ski poles and flicking it ahead of them to assist in defining the changes in the terrain. They periodically checked their bearings by compass and GPS and switched leaders. At one point N.F. believed that the group had veered too far left and corrected their course. As the group climbed toward the Col, visibility was initially quite reasonable and no worse than on previous days. As the group approached what they believed was the Col, the visibility dropped sharply. They were actually off-route to the extreme left edge of the traverse at this point.
The group checked their bearings by GPS and decided to unrope for the descent, as they felt they were beyond the obvious crevasses and could navigate reasonably well. They also removed their skins and Rutschblock cords and were having to travel shoulder to shoulder at that point in order to keep track of each other in the whiteout conditions. Each member was using a compass and/or GPS. N.F. was using a compass. His closest companion, G.M., noticed that he pushed off a couple times and then took a reading on his compass. He skied off away from the group, slightly to the left. It was at that moment, when N.F. was about 20 to 25 feet away, that
N.F. disappeared. N.F.’s companion was clearly also very close to the edge. G.M. believed that N.F. had skied over a wind lip. He skied toward N.F. but was warned by another member of the party to get back from the edge. It was then that they realized that he had gone over a cliff. When N.F. did not reappear, his companions shouted loudly, but received no response. Visibility improved slightly and they set up a rappel and looked over the edge. They realized the seriousness of the drop and could not see N.F They attempted to use the radio on a number of occasions over the next few hours to report the accident but were unable to make contact with anyone. They attempted to rappel onto the slope from the Col but due to cornice conditions and the difficulty of reversing the rappel they aborted this attempt. They made a number of other attempts to get to N.F. by various routes. S.F. had the most first aid training, and he entered the slope from the south where it was marginally safer and made his way to N.F., about two hours after the fall. S.F. determined that there was nothing that he could do to assist N.F.
It was obvious from the laceration that N.F. had fallen directly on his head. There was a fair amount of blood loss from this injury. When S.F. reached N.F., he was not breathing, was cyanotic, and had no carotid pulse. (As a side note, S.F. had set off at least two avalanches in his approach to N.F. and thus chose to exit to the north of the Col, which took him through an icefall, which he then crossed solo.) One of the group skied part of the way down to him so that they could come back through the crevasses roped up. The group spent the night at the Scott Duncan Hut, where they again attempted unsuccessfully to call for help on the radio. The following day they exited at West Louise Lodge and reported the incident to the RCMP. Storm and whiteout conditions continued for seven more days. N.F.’s body was recovered by a team of Parks Canada Wardens from Lake Louise and flown out by helicopter on April 19. N.F. was buried in 80 cm of snow but his companions had taken a reading on his location. He was wearing a transceiver which made it possible to locate him very quickly.
Whiteout conditions at the Balfour High Col are fairly common, and this is the second such incident at this precise location. The decision to unrope in good visibility at this point is common, as most of the crevasses on the way to the Neil Colgan Hut can be avoided. Since the party was not familiar with the terrain in good visibility, they likely underestimated the cornices and steep terrain to their left. The main error was in failing to remain roped up and utilize proper glacier travel techniques. The recommended way to travel on glaciers is to rope up as the “default” position. Exceptions can be made, but being in a whiteout, in unfamiliar terrain, is not one of the exceptions. Worse yet, we seem to be seeing people using “not roping up” as the default position and roping up when they sense an exception, which in turn gives “human error” an even greater chance of success.
Ski mountaineers traveling the Wapta traverse should be equipped with a compass, topo map and GPS where possible. Having a pre-marked route plan is important as well, as it is easy to make errors in navigation in difficult conditions.
