Over time the glacier forms an ice bridge that acts as a natural dam
The "ice bridge" in Argentina collapses and reforms every four to five years, but the timing was just right for one lucky photographer who managed to capture everything on camera last month.
Christian Grosso says he was one of 20 privileged people in Los Glaciares National Park that got to witness the spectacle.
The Perito Moreno glacier is located at the southern tip of South America. It stretches from over 6,500 feet above sea level in the Andes mountains, right down to the warm waters of Lago Argentino. The glacier forms an ice bridge that acts as a natural dam and prevents water from transferring between the two bodies.
Over time, water from the south piles up against the ice, causing the bridge to reach a breaking point with the pressure behind it. The ice bridge then cracks and crashes into the lake below, creating a huge wave.
Grosso and the other photographers were at a safe distance and say they were not affected by the water.
The same thing happened in March 2012 and experts say this latest collapse was the result of an ice bridge that was leftover.
The glacier acts as one of the largest reserves of fresh water in the world.
