Above you can see a closeup of this iceberg in the second picture.

Lago Argentino is the biggest fresh water lake in Argentina and can be found within the Los Glacieres National Park. The lake is fed by several glaciers of which impressive icebergs break off into the lake.

The amazing blue colour is actually not the result of post processing – they actually look like that.

The blue colour is created through hundreds of years of intense pressure within the glacier. The ice gets compressed more and more and so the air, that was originally trapped within the snowflakes get pressed out.

In the end the light, that hits such an iceberg, doesn’t get reflected by the air inside anymore (what creates the white colour), but gets filtered – in the end the weaker wavelengths of the light get filtered out (like in water) until just the blue remains …

To estimate the size of this iceberg – just the dimensions above water: 8 meters high, 30 meters long and another 10 wide (and as we know only the tip of the iceberg is actually showing)

  1. At some point in the past year I read an article about Patagonia that discussed Los Glaciares in general and the calving of blue icebergs in this lake in particular. Thanks for posting these great images.
