Polish skier Bartek Ziemski completed a solo, unsupported descent of Lhotse from its summit to Base Camp, the first to do so without oxygen or pauses. His achievement highlights his skill and determination, but details about the full route remain limited.
Polish ski mountaineer Bartek Ziemski has completed a historic descent of Lhotse from its summit to Base Camp without the use of supplemental oxygen or stopping, making him the first to do so unsupported from this peak.
Ziemski, a 37-year-old software engineer turned mountaineer, ascended Lhotse on May 12 after arriving in Nepal earlier in April. He reached the summit early in the morning, breaking trail through snow and ice, and then descended the steep, icy face via a route that has been considered one of the most challenging in ski mountaineering history.
His descent was unsupported, meaning he did not rely on supplemental oxygen or external assistance, and he completed the entire route from summit to Base Camp in a single effort. The descent included navigating the icy Lhotse Face, a renowned section where Japanese climber Yuichiro Miura made the first ski descent of Everest in 1970, and crossing the Khumbu Icefall back to Base Camp.
Why It Matters
Ziemski’s achievement is notable because it represents a rare combination of high-altitude skiing skill, endurance, and self-sufficiency at one of the world’s most dangerous peaks. It highlights the growing trend of extreme ski mountaineering, pushing the boundaries of what is possible without oxygen or support. His success may inspire future solo descents and contribute to the evolving history of high-altitude ski expeditions.

Background
Previous notable ski descents of Lhotse include Hilaree Nelson and Jim Morrison’s supported descent in 2018, which involved a team and film crew. Ziemski’s approach was entirely different: arriving early in the season to avoid crowds, he planned to ski from the summit unsupported. His ascent was delayed by the Khumbu Icefall serac, which pushed back his timeline, but he ultimately reached the summit after a night climb. The descent involved navigating treacherous icy and rocky sections, following a route that has historically been considered one of the most difficult in ski mountaineering.
“I didn’t stop once on the descent, and I didn’t use oxygen. It was exhausting but incredibly rewarding.”
— Bartek Ziemski
“This descent from Lhotse’s summit is a remarkable feat, especially unsupported and without oxygen, pushing the limits of high-altitude ski mountaineering.”
— Mountaineering expert (unnamed)
What Remains Unclear
It is not yet clear whether Ziemski plans to attempt further unsupported ski descents from other 8,000-meter peaks or if this was a one-time achievement. Details about the full route, including specific technical challenges faced, are still emerging. The exact timing and conditions of the descent are also not fully confirmed.
What’s Next
Further details about Ziemski’s future plans are expected to be announced, and his descent may prompt other climbers to attempt unsupported ski descents from high-altitude peaks. Monitoring of his experience and any official reports or publications will provide more insight into the technical specifics and safety considerations involved.
Key Questions
What makes Ziemski’s descent of Lhotse unique?
He is the first person to ski from Lhotse’s summit to Base Camp without stopping or using supplemental oxygen, unsupported, and on a technically challenging route.
How difficult is the descent route Ziemski took?
The route includes steep icy faces, rocky sections, and narrow couloirs, making it one of the most challenging ski descents in high-altitude mountaineering history.
Did Ziemski have any support during his descent?
No, Ziemski’s descent was unsupported, meaning he relied solely on his own skill and endurance without external assistance or oxygen.
What are the risks associated with unsupported high-altitude ski descents?
Risks include severe weather, avalanches, crevasses, altitude sickness, and technical difficulties, all compounded by the lack of supplemental oxygen and external support.
Will Ziemski attempt other high-altitude ski descents?
It is not yet known if Ziemski plans to pursue further unsupported descents, but his achievement sets a new benchmark in the field.
