On Wednesday, May 29, a massive section of the Birch Glacier collapsed in Switzerland’s Lötschental Valley. What followed was a wall of ice, rock, and sludge that tore down the mountain and buried the Swiss villa of Blatten.
It happened fast. It was expected. And still, it was overwhelming.
Roughly 300 residents had already been evacuated weeks before, after authorities noticed the glacier’s movement accelerating. It wasn’t enough. Ninety percent of the village is now under mud. One man is missing. Search crews are using drones with thermal cameras. The Lonza River is dammed. And everyone’s holding their breath.
The Images Speak for Themselves: A Swiss Village Buried by a Glacier
Blatten was a place you’d expect to find on the cover of a hiking guide—stone chalets, green slopes, a river cutting calmly through the valley. In the before photos, it looks untouched by time.
And then the glacier fell.
In the after shots, nothing holds. Roofs are half-submerged in sludge. The streets are untraceable. The Lonza River is blocked and swelling, forced to find new paths—or force its way out.
From above, it’s worse. The village isn’t damaged. It’s almost erased.
What took centuries to build disappeared in minutes. There is no metaphor needed. You can see it.

A Climate Threat That’s No Longer Distant
Switzerland has lost 10% of its glacier volume in just two years. What once took centuries to change is now shifting in weeks. Thawing permafrost, warmer temperatures, and weakened geological structures are setting up more collapses like this one.
Officials called this an “extraordinary event.” It’s not. Not anymore.
The collapse in Blatten follows near-misses in places like Brienz, where entire towns have evacuated just in time. The Alps aren’t stable. And everyone knows it.

What Comes Next—If Anything
The Lonza River is now partially buried. If it floods, more communities could be at risk. Swiss military forces have been deployed to monitor the site. Damage assessments are still underway. The man who’s missing hasn’t been found.
Swiss Environment Minister Albert Rösti said the government will help rebuild. But there’s not much to rebuild.
Blatten wasn’t just buried. It was erased.
