Ice caves not only amaze the imagination of tourists with their beauty, they are perceived as miraculous miracles - magic, which a person cannot repeat. One of these caves is located in Skaftafell Natural Park in Iceland, it is formed by centuries-old ice layers.

The glaciers that form the walls of this extraordinarily beautiful cave are so "compressed" that they practically do not contain air bubbles. The lack of air causes the walls of the cave to literally absorb all visible light, excluding blue. This explains the fact that the walls of Skaftafell amaze tourists with their unusual color - it seems that they are lined with sapphires, this can be seen even with the naked eye. This optical trick can not always be seen: usually in winter, prolonged rains wash away the upper layer of glaciers, and then from the inside the cave begins to shine like a precious stone. In addition, such a unique phenomenon can be observed on colorful icebergs that turn over in the water, and their surface also looks blue.

The cave was formed as a result of the fact that rain and melt water accumulates on the glacier, and then, flowing down in a powerful stream, forms a kind of tunnels. As already noted, the “ceiling” and “walls” of this mysterious tunnel are painted blue, but the “floor” of the cave is dark muddy tones, this effect is created by sedimentary rocks that “freeze” into the “bottom” of the glacier.

Perhaps, in its beauty, Skaftafell can be compared only with the largest ice cave Eisriesenwelt, one of the attractions of Austria, which we also talked about on the website Culturology.ru
