The Epic First Descent of Mount Robson’s Great Couloir
The South Face of Mount Robson, towering at 12,972 feet, stands as the highest peak in the Canadian Rockies and a formidable challenge for mountaineers. On February 13, Canadian ski mountaineer Christina “Lusti” Lustenberger and acclaimed IFMGA guide Guillaume “Gee” Pierrel embarked on an ambitious quest to achieve the first descent of this peak’s iconic Great Couloir. However, as the sun set and they reached just 650 feet from the summit, the duo made the critical decision to turn back, prioritizing their safety over ambition.
A Historic Climb against the Odds
Lustenberger and Pierrel were not new to this kind of challenge, having successfully completed a series of first descents on New Zealand’s Mount Cook just prior. Their current venture involved navigating a mountain that has historically tested climbers with its sheer enormity and unpredictable weather. Past legends such as Barry Blanchard and Marc-André Leclerc have made their mark on Mount Robson, but Lustenberger and Pierrel aimed to leave their own legacy.
The Challenges of the Descent
The descent proved significantly more daunting than the ascent. After a two-day climb, the team faced treacherous conditions, encountering mixed rock and ice while skiing through some of the worst snow they had ever experienced. Overcoming these obstacles required rigging seven rappels through a perilous landscape of decaying sedimentary rock and sheer ice—all while descending in darkness. According to Pierrel, “The skiing was terrible,” highlighting the unique difficulties they faced during this expedition.
A Second Attempt with Improved Conditions
Following a brief regroup in Valemount, Lustenberger and Pierrel returned to Mount Robson on February 15, equipped not just with skills but also with a film crew. After a fresh snowfall, conditions significantly improved, facilitating their ascent via the famous Kain Route. The duo enforced a strategy of timing their climb to avoid strong solar radiation, essential for maintaining the mountain’s challenging icy terrain.
Safety First: Navigating the Descent’s Dangers
As they descended back to safety, the pair was reminded of the risks inherent in their adventure. The Great Couloir, shaped like a funnel, posed a constant threat of falling rock and ice. With experience gained from their initial attempt, they efficiently navigated the previously established rappels to enhance their safety on this challenging route. Describing it as “playing Russian Roulette,” Pierrel expressed the intricacies of managing speed while remaining vigilant of hazards falling from above.
Reflections on Risk and Achievement
Lustenberger’s history with Mount Robson spans a decade. Her motivation to conquer this peak was fueled by a deep passion for adventure and an established trust with her partner, Pierrel. Their differing styles of risk management, with Pierrel leaning towards caution as a guide, created an interesting dynamic throughout the expedition. Ultimately, they managed to complete the ski descent on February 16, solidifying their names in the pantheon of great mountaineers associated with Robson.
The Future of Ski Mountaineering
With the successful descent behind them, Lustenberger and Pierrel are looking forward to documenting their adventure in a film set to release in late 2025, produced by Sherpa Cinemas. When asked about future endeavors, Pierrel hinted at a desire to ski the Hornbein Couloir on Mount Everest, a line comparable to Robson’s Great Couloir. However, for now, both mountaineers expressed their need for a well-deserved break, contemplating a peaceful retreat to the sauna.
