Perito Moreno Glacier
The glacier was one of the highlights of the trip so far. There has been a lot of those so you can just imagine how spectacular the glacier is!
The glacier is 4 km in width and 14km in depth! On average it is 60 metres high above water level and 180 metres below. It is one of the only glaciers in Patagonia, which is not retreating. It moves nearly 2 metres a day but this is impossible to see as it loses mass at the same time. We stood and watched as huge blocks of ice fell from the glacier. The sound was incredible. We then took a boat trip to get closer. Why is the glacier blue? Read the following as I am sure you will notice it is not my words!
"White light travels on a long wavelength, blue on a short wavelength. Air bubbles in ice or snow absorb white light, thus appearing white, but the weight of this glacier, however, squeezes all the air out of lower levels, so white light cannot enter, only short wavelength blue. The more compact the ice, the bluer it gets; the cloudier the day the bluer too"

Huge chunks of ice fall from the glacier regularly.
