The Perito Moreno Glacier is located in the Santa Cruz province of Argentina, 80km from El Calafate, a charming little town with a beautiful lake, surrounded by snow capped mountains.
The glacier itself is 250km2, 30km in length, and is one of the few glaciers in the world that is actually advancing. Large blocks of ice continuously fall off the face with a thunderous crash, creating ice bergs and a spectacle worth watching!
The glacier advances as much as 2 metres per day, and the gap between land and ice is getting smaller. Every few years the ice reaches the land, but the pressure from the water under the ice causes the ice to break off and start the process all over again.
The ice looks blue as a result of oxygen trapped in the snow, which is compressed over time.
