F-6 Fighter Aircraft – JhelumTragic Avalanche Claims Life of Renowned French Mountaineer on K6 in Pakistan
On June 24, 2026, esteemed French mountaineer and IFMGA-certified guide Guillaume “Gee” Pierrel, 42, tragically lost his life in an avalanche while attempting to summit K6, a formidable peak in Pakistan’s Gilgit-Baltistan region. Pierrel was accompanied by fellow climbers Boris Jule from France and Christina Maria from Switzerland. The incident occurred at approximately 5,000 meters (16,400 feet) during their ascent, when a sudden avalanche of snow and rocks swept over the team, resulting in Pierrel’s immediate death.

Both Jule and Maria survived the avalanche and are actively involved in the recovery efforts. Ishaq Ali, the tour operator assisting with the recovery, reported that the team managed to bring Pierrel’s body down to Camp I. However, due to high temperatures in the Baltoro Glacier region, which are expected to reach the 90s Fahrenheit this week, helicopter evacuation has been delayed. The team remains hopeful that a helicopter will be able to fly today to facilitate the transfer. (dailytimes.com.pk)
Pierrel’s partner, Christina “Lusti” Lustenberger, had previously announced their joint expedition to Pakistan. Sources close to Lustenberger confirm that she is alive and was at a lower camp during the avalanche. She is currently making her way off the mountain. (dailytimes.com.pk)
Renowned steep skier Aymar Navarro paid tribute to Pierrel on social media, expressing his sorrow and admiration for his friend. Navarro wrote, “Goodbye Gee, goodbye my friend. Still processing the sad news of your loss. It’s hard that the mountains give us the best of ourselves and at the same time tear us apart like this. Watch over us from wherever you are, my friend.” (dailytimes.com.pk)
Guillaume Pierrel: A Legacy in Ski Mountaineering
Born in 1983 in the Vosges region of France, Pierrel was introduced to skiing at the age of two and began climbing in the Swiss Alps at four. He rapidly advanced through his mountain guide training, undertaking numerous challenging ski descents in Chamonix. In February 2025, Pierrel and Lustenberger achieved the first descent of The Great Couloir on the South Face of Mount Robson in British Columbia, Canada. This nearly 10,000-foot-long couloir presented a formidable challenge, requiring stable rock and snow conditions for a safe descent. The team skied it early in the season in sub-zero Fahrenheit temperatures to minimize the risk of rockfall. (dailytimes.com.pk)
Earlier, in 2024, Pierrel and Lustenberger skied a new line on Aoraki (Mount Cook), New Zealand’s highest peak at 12,218 feet. An IFMGA guide, Pierrel was known for his impeccable alpine style—traveling light and fast, carrying only what was necessary for a quick descent. (dailytimes.com.pk)
In 2021, as a solo skier, Pierrel completed the first ski descent of the French Spur on Gasherbrum I, one of the 14 peaks in the world higher than 8,000 meters (26,426 feet). (dailytimes.com.pk)
K6: A Challenging Ascent
K6, also known as Baltistan Peak, stands at 7,282 meters (23,891 feet) in the Masherbrum range of the Karakoram in Gilgit-Baltistan, Pakistan. The Masherbrum Range lies just south of the Baltoro Glacier, famed for being home to 8,611-meter (28,251-foot) K2, the world’s second-highest mountain, and the Trango Towers, a renowned climbing and skiing arena.

K6 has only been summited once, in 1970, via the Southeast ridge by Eduard Koblmüller and a team from the Austrian Alpine Club. Alpinist Wolfgang Axt described K6 as “possibly the most difficult 7,000-meter peak in the Karakorum.” (dailytimes.com.pk)
The region has experienced elevated risks in recent years. In early June 2026, the Pakistan Meteorological Department forecasted ongoing rain and thunderstorms, maintaining a critical risk of Glacial Lake Outburst Floods (GLOFs) and flash floods across glaciated valleys in Gilgit-Baltistan. Over 7.1 million people in these northern regions remain vulnerable. (communityworldservice.asia)

As investigations into the avalanche continue, the community reflects on the inherent risks of high-altitude climbing and the importance of safety measures.
This is a developing story, and updates will be provided as more information becomes available.
Our condolences go out to Pierrel’s friends, family, and the skiing community. He will be missed.
