Bare rock is emerging between Scex Rouge and Tsanfleuron glaciers as they melt at an accelerated rate

The mountain pass is already partially free of ice that had covered it since at least the Roman era.

The thick layer of ice that has covered a Swiss mountain pass for centuries will have melted away completely within a few weeks, according to a local ski resort.

After a dry winter, the summer heatwaves hitting Europe have been catastrophic for the Alpine glaciers, which have been melting at an accelerated rate.

The pass between Scex Rouge and Tsanfleuron has been iced over since at least the Roman era.

But as both glaciers have retreated, the bare rock of the ridge between the two is beginning to emerge – and will be completely ice-free before the summer is out.

“The pass will be entirely in the open air in a few weeks,” the Glacier 3000 ski resort said in a statement.

While the ice measured about 15 metres (5oft) thick in 2012, the ground underneath “will have completely resurfaced by the end of September”.

The ridge is at an altitude of 2,800 metres in the Glacier 3000 ski domain and effectively marks the border between the Vaud and Valais cantons in western Switzerland.

Skiers could glide over the top from one glacier to the other. But now a strip of rock between them has emerged, with just the last remaining bit of ice left.

Glaciologist Mauro Fischer, a researcher at Bern University, said the loss of thickness of the glaciers in the region will be on average three times higher this year compared to the last 10 summers.
