Mountain melt shutters classic Alpine routes

Little snow cover and glaciers melting at an alarming rate amid Europe’s sweltering heatwaves have put a few of the most classic Alpine hiking routes off-limits.

Usually at the height of summer, tourists flock to the Alps and look for well-trodden paths around a few of Europe’s most iconic peaks.

But with warmer temperatures accelerating and thawing permafrostwhich scientists say are driven by routes which are usually safe this time around of year now face hazards like falling rocks released from the ice.

“Currently in the Alps, you can find warnings for about twelve peaks, including emblematic ones like Matterhorn and Mount Blanc,” Pierre Mathey, head of the Swiss mountain guide association, told AFP.

That is happening far earlier in the growing season than normal, he said.

“Usually we see such closures in August, however now they will have started by the end of June and so are continuing in July.”

‘Postpone’

Alpine guides who usually lead a large number of hikers up towards Europe’s highest peak announced earlier this week they would suspend ascents on probably the most classic routes up Mont Blanc, which straddles France, Italy and Switzerland.

The Guide Alpine Italiane said on its Facebook page that the “particularly delicate conditions” due to the temperature spike managed to get essential to “postpone the climbs”.

Mountain guides also have refrainedreportedly for the very first time in a centuryfrom offering tours up the classic path to the Jungfrau peak in Switzerland.

Plus they have advised against tours along routes on both Italian and Swiss sides of the towering pyramid-shaped Matterhorn peak.

Ezio Marlier, president of the Valle D’Aosta guides association, said needing to stay away from routes most coveted by tourists was a blow following the Covid slowdowns.

“It isn’t easy… after two almost empty seasons to choose to prevent work,” he told AFP.

He stressed that the Italian Alpine region had shut only two and that there have been a great many other breathtaking and safe routes to take.

But he lamented that lots of people simply cancelled their trip if they heard their preferred was off-limits.

“There are many other things to accomplish, but usually when people want Mont Blanc, they need Mont Blanc.”

Dangerous glaciers

Climbing on a number of the a large number of dotting Europe’s largest mountain range can be proving trickier.

“The glaciers come in a state they are usually in by the end of the summertime as well as later,” said Andreas Linsbauer, a glaciologist at Zurich University.

“It really is sure that we shall break the record for negative melts,” he told AFP.

He said a variety of factors were adding to a “really extreme” summer, you start with exceptionally little snowfall last winter, meaning there is less to safeguard the glaciers.

Sand also blew up from the Sahara early in the entire year, darkening the snow, that makes it melt faster.

And the initial heatwave hit Europe in-may, with subsequent ones following in June and July, pushing up temperatures even at .

The rapid melting could make glaciers more threatening, as seen with the sudden collapse of Italy’s until then seemingly harmless Marmolada glacier earlier this month, which saw 11 people killed as ice and rock hurtled down the mountain.

While scientists have yet to draw clear conclusions on which caused the disaster, one theory is that meltwater could have reached the stage where the glacier was frozen to the rock, loosening its grip.

‘Invisible threat’

Mylene Jacquemart, a glacier and mountain hazard researcher at Zurich’s ETH university, told AFP there have been many unknowns concerning the catastrophe.

“However the general theme is certainly that more meltwater… makes things complicated and potentially more threatening.”

Mathey, who said had put mountain guides on high alert, also voiced concern that meltwater filtering under a glacier posed an “additional and invisible threat”.

But regardless of the challenges, he voiced confidence that guides would find solutions, searching for alternative routes to help keep revealing Alpine splendours.

“Resilience is actually in the guides’ DNA,” as is adaptability, he said.

“Humans need to adjust to nature also to the mountains, not another way around.”
