Massive Ice Arch Collapses In Patagonia
An ice arch 70-meters high and 250 meters wide had a spectacular collapse in Patagonia on Thursday. The natural display occurs once every few years and was captured on film at the tip of a glacier in southern Argentina. Phys.org reports: Thousands of tourists had gathered at the Perito Moreno glacier hoping to see the collapse of the pale blue bridge that had formed between the glacier and the shore of Argentino lake.
