This incredible pictures were taken near Mutnovsky volcano, Kamchatka krai in 2012. Though last winter wasn’t that cold and snowy like before and the summer was really hot, that’s why the huge snow piles started to melt opening a way into the underground cave which was never seen before. The total length of the cave is around 300 meters and is located in a ravine 10 meters depth with an ordinary mountain stream.
The game of lights and snow creates stunning images by the entrance, as the ceiling at this point is not so thick. As you move further in, the walls become and the cave itself becomes thicker but sun light still comes through creating unique images of various colors and shapes.
