Huge chunk of glacier falls into Lake Argentina

Check out these amazing pictures of a chunk of glacier breaking off in Argentina.

The huge lump of ice is a whopping 70 metres tall but grows in size thoughout the year and can grow big enough to separate the lake in two.

The Perito Moreno glacier is one of the few glaciers in the world that isn't shrinking.

The last time a piece of the ice broke off was in 2008, so the tourists were pretty lucky to catch a glimpse of it!
