Fantastic Ice Cathedral Grotto Under Norway’s Glacier

Melting ice has created a fantastic "ice cathedral" in a grotto under the Nigard Glacier, one of Norway’s major glaciers:
The ice grotto is "fantastic," with "extremely blue" colors and large icicles hanging from its ceiling. "But it’s changing from day to day."
The grotto is believed to have been created by rising temperatures. "It’s the running water under the ice that has made the ice over it melt." LINK
