We have seen quite a few glaciers but the Perito Moreno glacier which flows from the South Patagonian Ice Cap is definitely The Big Daddy. Like the ice monster in your freezer compartment, this glacier is one of the few in the world which is still advancing. Fed by snowstorms falling above, it flows down the valley like a massive, crinkled river of ice, creaking, groaning and rumbling. It ends in an ice cliff face, over 150 feet high and over 3 miles wide, where huge pieces of blue-white ice roar and crash into the lake below. It's hard for the mind to grasp the sheer size of it, but this photo gives you some idea - I am the tiny figure on one of the viewing platforms.
