Following the hottest summer in Europe on record, a path usually covered by ice and snow has been uncovered for the first time in at least 2,000 years.
"Ten years ago I measured about 15 metres of ice. So more than 15 metres of ice and snow have melted," says Mauro Fischer, a glaciologist at the University of Bern's Institute of Geography.
Bare rock can now be seen between the Scex Rouge and the Zanfleuron glaciers at an altitude of 2,800 metres, and the pass is expected to be completely exposed by the end of this month.
Why is the ice melting so dramatically in the Alps?
Since last winter, which brought relatively little snowfall, the Alps have sweltered through two big early summer heatwaves. Not only did a hot, dry summer melt snow and ice but the lack of rain means there’s very little to replenish it.
"What we saw this year and this summer is just extraordinary and it's really beyond everything we have ever measured so far," Fischer adds, referring to the speed at which the ice has melted.
