Sunday afternoon, all of Monday and Tuesday morning were spent in El Calafate, way down in the south of Argentina.
This glacier, 78km south of El Calafate, was just gorgeous and unlike anything I have seen before.
This is the Perito Moreno Glacier in the in the Los Glaciares National Park in southwest Santa Cruz Province, which is in the Patagonian area of Argentina.
I learnt how a glacier is formed (compacted snow high up in the mountains) and why the blue colour is so prominent (the densest ice filters all of the colour wavelengths except blue).
This glacier moves at around 20m a day and is constantly 'calving', or ice breaking off. I saw two smaller calving events and one big one, but missed them all with the camera.
