Mountains are collapsing: A Swiss mountain peak fell apart, sending 3.5 million cubic feet of rock into the valley below. Scientists warn climate change could make more mountains crumble.

Mt. Fluchthorn's tallest peak collapsed earlier this year, and it's just one of many crumbling examples most likely to come within the next decade.

Mt. Fluchthorn’s tallest peak, on the Swiss-Austrian border, collapsed in June.

Experts say peaks in the European Alps and Southern Alps of New Zealand are at risk of collapse, too.

The damage and dangers from mountain collapse disproportionately impact indigenous communities.

On June 11, the main peak of Mt. Fluchthorn, on the border of Austria and Switzerland, collapsed without warning.

Roughly 3.5 million cubic feet of earth tumbled down, filling the valley below with 40 Olympic swimming pools’ worth of rocks, mud, and dirt, LiveScience reported. While no people got hurt, a religious cross marking the summit was destroyed.

Fluchthorn had three peaks, and the main, southern one used to be the tallest. With the south peak collapsed, the middle peak is the new summit at 11,145 feet — the second-highest summit in the Silvretta Alps.

Overall, Mt. Fluchthorn is 60 feet shorter than it was earlier this year, per LiveScience.

Why did the peak collapse? Well, like many mountains in the far north, Fluchthorn had a lot of permafrost — a permanent layer of ice and dirt under the mountain’s surface.

“Permafrost is important because frozen water within the ground holds the ground surface together and prevents it from moving. But when that ice melts, the liquid water can flow away. The ground surface becomes less stable and can move, often very quickly,” said Jasper Knight, a geoscientist at the University of Witwatersrand in South Africa.

When a big chunk of mountain moves quickly, like with the mudslide at Fluchthorn, that’s called a mass movement.

“Global warming is causing the permafrost to melt, which is the trigger for these mass movement events to take place,” Knight said.

    I don’t know about you guys, but this reality is starting to feel more and more like the things that we used to see in movies. The kind of things that were so bizarre that we scoffed at. I don’t like where this is all heading, especially considering it’s happening much faster than initially predicted. It just keeps gaining momentum.

    I know we’re not doomed yet, but most people don’t seem to give a hoot. Others see snow and denounce that any of this has anything to do with global warming. It’s a bit depressing sometimes, tbh.

    It makes sense to me now, but I never thought that I would see a headline like this.
