Perito Moreno glacier's ice bridge breaks off

13 March 2018

In Argentina's region, an ice bridge broke off from the Perito Moreno glacier over Saturday and Sunday. It is in a cyclical phenomenon that attracts thousands of tourists. The glacier covers 250 square kilometres, advances yearly into a lake, known as Lago Argentino. As Perito Moreno moves forward, it cuts off a river feeding the lake. Water builds up pressure and slowly undermines the ice, forming a tunnel until ice comes tumbling down. The ice bridge broke off late Sunday  and chunks of ice are expected to fall within the next few days. The last rupture was in 2016.
