Rainbow Ice Caves in Russia Are Unlike Anything You've Seen

It's unlike anything you've ever seen: rainbows 'trapped' in ice. These colorful ice caves, formed by heavy winter snows and carved by summer melting in southern Kamchatka, Russia, could collapse at any moment.  

"It was pretty cold and wet inside and the water was flowing down from the roof and walls," Budkov told the media. "It was zero degrees inside, too, and the lens was getting damp – making it hard to shoot."

"When I got deeper inside the caves, I was amazed by the colors I saw. I haven’t seen anything like this before," Budkov said. "The emerald colors of the ice were spectacular and worth the risk of the roof caving in to capture the pictures."

The myriad colors are created by light reflecting through the ice, with the most colorful sections consisting of thicker ice, Metro says.
