One of the world's biggest glaciers has collapsed into the sea in Argentina.
The glacier caved in bringing tonnes of ice crashing into icy waters, forming lots of little icebergs.
The wall of snow, called Perito Moreno, was around 20 miles long and 70 metres above the level of the sea.
It's one of the biggest tourist attractions in the South American country as it's the largest of 356 glaciers in the area. The last time it collapsed was 16 years ago.
The glacier, which started to break down on Friday, falls down every few years.
A massive pond builds up behind the wall of snow before getting too heavy for the ice to hold and smashing down into the sea below.
