As Mont Blanc Cliffs And Spires Collapse, So Do Climbing & Hiking @ One Of EU's Most Popular Spots
EDIT
In the Mont Blanc range, a magnet for mountaineers in the summer, many popular routes up or through the peaks have become too dangerous to take because of the risk of falling debris. “It’s going quickly. Ten years ago, I’d have never thought that it would accelerate like this,” said Ludovic Ravanel, an academic at the University of Savoie Mont Blanc who has been studying major rockfalls in the area. “And if you look at the predictions from my climatologist colleagues, for the next 10 to 20 years, it’s only going to get worse,” he told AFP.
In many areas of western Europe, climate change is happening too slowly to be noticed, although two record-setting heatwaves in June and July this summer as well as water shortages are focusing minds. Around Mont Blanc, the warming has already left physical scars.
In 2005, following a major heatwave two years earlier, a huge shard of granite called the Bonatti pillar suddenly collapsed, spewing 292,000 m3 of rock into the valley below and stunning the mountaineering community. With it went a feature visible from the nearby resort town of Chamonix, as well as the dreams of many climbers hoping to take on a legendary challenge named after celebrated Italian mountaineer Walter Bonatti.
Major rockfalls on less famous routes continue regularly, without fanfare, and would go unnoticed were it not for the work of researchers like Ravanel who tracked them for his PhD. Occasionally, they register more widely in the climbing community, like a collapse on the Arete des Cosmiques ridge last summer that is often taken by beginners hoping to take on the 4,810-metre Mont-Blanc peak, the highest in western Europe.
