The mountain doesn't pause. It never has. But for those who live beneath Mont Blanc, 2026 has been a year that makes that truth impossible to ignore — a season of avalanches and rescues, vanishing ice, and a valley quietly reinventing how it moves through the world.
The day the mountain came down
On a Tuesday afternoon in late February, the Flégère ski area looked ordinary. Skiers carved down the red Crochues piste. The lifts hummed. Then, at around 1:30 p.m., a slab the size of several football pitches released from the steep, rocky terrain above the Floria T-bar.
It was a D3 — a large avalanche by any measure — and it didn't stop at the boundary of the ski area. It crossed two groomed runs, the kind of runs where parents take their kids, where beginners find their confidence. Three skiers were partially buried, one up to chest height. Somehow, none died.
What followed was a response that says everything about this community. Seventy-seven people — ski patrollers, mountain guides, instructors, gendarmes, members of the public — converged on the slope within minutes. The buried skiers were freed. The injuries were serious but not fatal.
This winter, avalanches had already killed 100 people across the Alps. Chamonix's number stayed lower — not by luck alone.
It stayed lower because of the culture of vigilance and readiness that runs through this place like a seam of granite.
Nine rescues before dark
The PGHM — the Peloton de Gendarmerie de Haute Montagne — is the busiest mountain rescue unit in the world. On Sunday, March 8th, they earned that title again.
By the end of the day, they had carried out nine separate rescues. The first was a skier with a knee injury in the Vallée Blanche before most people had finished breakfast. Then the Dragon helicopter was up and away: to Mont d'Arbois in Saint-Gervais, to the Balme ski area, to the Améthystes Glacier, to the Col du Passon, to the Glacier du Tour. Leg injuries, knee injuries, shoulder injuries — the full toll of a valley where the terrain never flatters mistakes.
To live in Chamonix is to carry a quiet awareness of these people. The sound of the helicopter is so woven into valley life that locals barely look up. But they know. On a single Sunday in March, nine families got their person back. That's what the PGHM does, day after season after decade, without ceremony.
The glacier doesn't lie
Walk down to the Montenvers train station. Look at the photographs on the wall — the ones showing where the Mer de Glace stood in 1900, in 1950, in 1980. Then ride the train up and look at the glacier itself.
The gap between the photographs and the reality is the story of our time.
France's largest glacier is losing six metres of thickness every year. In places, glaciologist Luc Moreau — who has been measuring it since 1987 — has recorded 40 metres of loss in just four or five years. Mountain guides like Jérôme Stoessel now walk their clients further and further upstream just to reach ice worth training on. What was once the approach has become the destination.
Scientists say the Mer de Glace could be gone entirely by 2100. Some who grew up in this valley will live to see it.
This summer, a new chapter opens at Montenvers: the Glaciorium, an international glacier and climate interpretation centre. It won't stop the ice from melting. But it will make sure no visitor — and no local — can stand here without understanding what they are witnessing. The valley is choosing to be honest about what is happening to the mountain it is built around. That takes a particular kind of courage.
A new train for an old line
The Mont-Blanc Express has been running since 1908. It is one of the oldest mountain railway lines in the world, connecting Le Fayet to Martigny through 117 years of weather, politics, two world wars, and enough powder days to fill a lifetime.
This autumn, it gets its first new trains since 1996.
Seven Z890-type trains, built by Swiss manufacturer Stadler at a cost of €55 million, will begin rolling into service on the French and Swiss sides of the line. They carry 224 passengers, with nearly flat floors for accessibility and space designed for skis and bicycles. Blue towards France, red and white towards Switzerland — a compromise painted in metal, stitching the two countries together as the line always has.
For valley residents, the Express is not a tourist attraction. It is the school run, the commute, the way home when the road is blocked by snow or rock or the sheer indifference of the mountain. New trains matter here in the way that new buses matter in any town — practically, daily, personally.
The summer that's coming
As the snow retreats from the lower slopes and the lifts reopen for hikers and mountain bikers, Chamonix is already looking ahead to what comes next.
In early July, the Arc'teryx Alpine Academy returns — over 80 clinics led by IFMGA guides and world-class athletes, covering everything from glacier travel to mixed climbing. It is one of the finest gatherings of mountain knowledge anywhere on the planet, and it happens here, in this valley, because this valley is where that knowledge lives.
A week later, the World Climbing Series comes to Chamonix. The best competition climbers on earth, set against the backdrop of the Aiguilles. For a few days, the world will look at Chamonix and see not just a ski resort but what it has always been: a place where humans come to test themselves against something larger than themselves.
What stays the same
The glacier retreats. The trains get newer. The helicopter goes up nine times in a single Sunday. The mountain sends its snow down without warning and 77 people run toward it.
Chamonix in 2026 is a place caught between what it was and what it is becoming — a high valley feeling the weight of a warming world, while carrying forward the instincts and the skills and the solidarity that have always defined it.
The mountain doesn't pause. Neither does the valley that grew up in its shadow.
