Glaciers protect alpine peaks
Saturday August 3, 2013 - Email this article to a friend

New research shows the ice protects peaks from erosion caused by rain and wind. Scientists have been studying erosion on Mont Blanc.

They have declared that mountain areas without glacial cover are like to suffer 10 times more erosion.

In the past some had believed the movement from the glacier and the thawing caused harm to the mountain rock underneath.

The study examined the Bossons glacier which flows down the north face of Mont Blanc to the valley floor. It is the glacier that comes down the mountain on the right hand side when driving into Chamonix from the west.

Rocks that ended up at the end of the glacier were takes along with rocks washed out in high mountains streams and compared to rock samples taken from non-glacier areas.

The rocks from glacial areas were better protected from erosion.

The findings are recorded in the journal Earth and Planetary Sciences Letters and reported on the BBC.

A different group of scientist reported earlier that the glaciers on Mont Bland and elsewhere in Europe are melting at an increasing rate.

We reported on that story here on PlanetSKI.

For the spirit of the mountains
