The sapphire walls of the ice cave Skaftafell





Ice caves not only amaze tourists with their beauty, they are perceived as a miraculous miracle – magic, to repeat which is not given to man. One of these caves located in the natural Park of Skaftafell in Iceland, it was formed centuries of ice layers.





The glaciers that form the walls of this incredibly beautiful cave, so "compacted" that contain virtually no air bubbles. The absence of air leads to the fact that the walls of the cave literally absorb all visible light except blue. This explains the fact that the walls Skaftafell amaze tourists with its unusual color – a feeling that they are laid with sapphires, it is visible even to the naked eye. This optical trick, you can see not always: normally in the winter the rains wash away the top layer of glaciers, and then inside the cave begins to Shine like a precious stone. In addition, this unique phenomenon can be observed on the colorful icebergs, which overturned in the water, and their surface looks blue.





The cave was formed due to the fact that rain and melt water accumulates on the glacier, and then down the mighty stream, forming a kind of tunnel. As already noted, the "ceiling" and "walls" of this mysterious tunnel painted blue, but the "floor" of the cave – dark, murky tones, this effect is created by sedimentary rocks, which "freezes" at the "bottom" of the glacier.
