Alberta, Jasper National Park, Mount Athabasca, North Face
On August 15 at 0530, four Calgary-based climbers started their ascent up the trail to Mount Athabasca’s north face. The overnight low at 2,3 50 metres, recorded at a nearby weather station, was 9.5 C. At 1030, the party of four were at the bergschrund below the north face. N.B. (23) and F.L. (30) started to solo the route while the remaining two, T.R. (24) and J.M. (26) started simul-climbing with running belays. After ascending approximately 110 metres, the group encountered rockfall. At this point N.B. and F.L. roped up. The group continued their ascent and a short time later encountered more rockfall with very large blocks.
The leader, J.M., and T. R. were struck by the rocks and fell approximately 40 metres. Being much lighter, T.R. was pulled upward seven metres towards their ice screw running belay. During the incident J.M. sustained a life-threatening compound fracture of the femur. T.R. sustained significant internal injuries. F.L. and N.B. immediately came to the assistance of their friends, lowering them two pitches to the base of the route. By this time J.M. was reported to have the symptoms of hypovolemic shock and was drifting in and out of consciousness. F.L. ran down the glacier to get help. Parks Canada staff at the Icefields Centre noticed a single person running down the glacier waving his arms, so they called the Warden Dispatch office, which started to assemble a rescue team. At 1245 F.L. contacted the Jasper Warden Service from a phone at the Columbia Icefields Visitor Centre by which time a helicopter was already on standby in Canmore, Alberta. A rescue was initiated and at 1430, a rescue team arrived and started to evacuate the three remaining climbers. By this time J.M. had already died from his injuries. T.R. was transported to hospital for treatment.
At this time of year it is not uncommon for freezing levels to remain above 3,200 metres (10,500 feet) in this area. Under such circumstances any route with mixed rock and ice terrain below this elevation is subject to rockfall exposure. Many of the classic routes on the north face of Mount Athabasca have this type of terrain above with the exception of Silverhom. Compounding this problem is the unprecedented extent and rate of melt-off that has taken place over the past five years in this area. These factors necessitate careful evaluation as to the probability of rock and icefall on any given morning. With daytime warming, the likelihood of rockfall increases. Therefore, by completing a route early in the day you reduce the probability of rockfall. It is not uncommon for persons to do the approach to the glacier in the dark which requires a 0330 start, putting them at the toe of the ice for first light at 0530. It is not uncommon for climbers to be off the route by 1130. (Source: A1 Horton, R. Wedgwood, Jasper National Park Warden Service)
