A deadly Easter weekend saw at least three people, including a mountaineer and a snowboarder, killed in separate avalanches across the Swiss Alps, contributing to an above-average number of avalanche incidents this winter.

"Such conditions are hard to detect in the field, even for experts, and avalanches released deep in the snowpack tend to be large and dangerous."
Switzerlandâs Easter celebrations have been shattered by a trio of mountain tragedies as the Alps reclaim their reputation for lethal unpredictability. Within a single weekend, three outdoor enthusiastsâa mountaineer, a snowboarder, and a freeride skierâmet their ends in separate, violent snow slides across the country. On the Grossen Mythen in Central Switzerland, a young mountaineer was hurled down a rock face to his death on Good Friday, while his companion narrowly escaped by clinging to a tree in a desperate act of survival. Meanwhile, in Canton Bern, a 41-year-old snowboarder was buried near RĂŒschegg, and a 35-year-old skier perished in Isenfluh despite immediate rescue efforts by bystanders. These are not isolated incidents; they are the latest casualties in a winter season that has seen 15 lives lost to the mountains. The suddenness of these strikes serves as a grim reminder that even as spring arrives in the valleys, the high peaks remain a high-stakes arena where a single misstep or a shift in the wind can prove fatal.
A staggering instability is lurking beneath the pristine white surface of the Swiss Alps, creating a 'perfect storm' for avalanche triggers. Experts at the WSL Institute for Snow and Avalanche Research (SLF) warn that the primary culprit is a fragile layer of old snow, a structural weakness born from a dry, sunny January that followed an early winter start. This 'old snow' problem is notoriously deceptive; it creates large, deep-seated avalanches that can be triggered even by a single person. These weak layers are nearly impossible to detect with the naked eye, confounding even seasoned mountain guides and professionals. When these layers collapse, they release massive slabs of snow that move with terrifying speed and force. Most of the 13 fatal accidents recorded this season were triggered in these specific weak layers. The danger isn't just on the surfaceâit is baked into the very foundation of the winter's snow accumulation, making every off-piste excursion a calculated risk.
The numbers are in, and they paint a picture of a winter season that has pushed Swiss rescue services to their absolute limits. By the end of March, an alarming 244 people had been caught in 171 avalanchesâa massive surge compared to the 10-year average of 182 people in 127 incidents. This represents a nearly 35% increase in the number of people finding themselves in the path of a slide. While the death toll of 15 remains within the statistical norm, the sheer volume of close calls is unprecedented. Between January 10th and February 22nd, avalanches involving humans were recorded almost daily, creating a relentless cycle of emergency deployments. Thirty-seven individuals were completely buried this season, surviving only through the rapid intervention of companions or specialized rescue teams. This spike in activity highlights a volatile mountain environment where the frequency of danger has outpaced historical expectations, leaving no room for complacency among the Swiss public.
Geography has dictated the lethality of this winter, with Valais, Ticino, and GraubĂŒnden bearing the brunt of the most extreme conditions. In mid-February, the situation reached a critical breaking point when Lower Valais was hammered by up to 150cm of fresh snow in a matter of days. This forced authorities to raise the avalanche danger to Level 5âthe maximum possible ratingâon February 17th. Such a rating is rare and indicates that large, spontaneous avalanches are certain. Even as conditions appeared to ease in early March, the southern side of the Alps saw a rapid deterioration. The Cantons of Valais and GraubĂŒnden remain the most dangerous hotspots, where the combination of steep terrain and heavy snowfall continues to trigger human-caused slides. The Bernese Oberland also joined the list of high-risk zones this Easter, proving that no region is immune when the weather shifts. These regional variations demand hyper-local awareness from anyone venturing into the backcountry.
As Switzerland moves toward the end of the hydrological year in September, the shadow of this deadly winter looms large over the mountaineering community. The Swiss Alpine Rescue and Cantonal Police are bracing for a difficult spring, as warming temperatures can further destabilize remaining snow slabs. The tragic Easter weekend serves as a stark warning: the mountains do not care about the calendar. For the Swiss people, the Alps are a source of national pride and recreation, but this season has forced a national reckoning with the inherent risks of high-altitude sports. Moving forward, the SLF will continue to monitor the 'old snow' problem, but the ultimate responsibility lies with the individuals. Education, proper equipment, and a willingness to turn backâas the two men on the Grossen Mythen tried to doâare the only defenses against an environment that remains fundamentally indifferent to human life. The 2025-26 season will be remembered not just for the snow, but for the lives it took and the lessons it left behind.
