The Patagonian ice fields extend for about 16,800 km2, covering part of Chile and part of Argentina’s geography. Even though that more than 80% falls into Chile (such as Glacier Grey, in Torres del Paine and Glaciar Aguila, in Agostini Sound), Argentina offers easy access to some of the most impressive glaciers in the continent (among them, the upmost famous Perito Moreno!).
While in Calafate, we decided to take a boat trip through Los Glaciares National Park – a World Heritage site since 1981. The trip took us along a small part of Lago Argentino, the largest lake in the country – coming so close, you could almost touch the ice!
Among all the white icy islands we came across with throughout the tour, there were also a few intense blue bodies of ice. It appears blue because this ice is very compact and so absorbs all colors of the visible light spectrum, except blue – which is transmitted instead. The deeper under the surface of the visible glacier, the more compact the ice becomes and therewith, the bluer it reflects when a piece of it cracks and ends up floating in the water.
