BUENOS AIRES, Argentina (AP) — Park officials say one of Argentina's most famous glaciers has begun a rare winter rupture.
Carlos Corvalan is director of the country's Glacier National Park. He says there is no record of such an ice break during the southern hemisphere's winter months, June through August. Breaks during summer melts happen regularly.
The break began Friday morning, officials said.
Corvalan said the rupture could be caused by global warming.
The Perito Moreno glacier cuts Lake Argentino in two. Water flows beneath the ice when the level on one side of the lake rises higher than the other. The rushing water erodes the ice and sometimes causes it to collapse.
