Though the Jostedal glacier had bucked the trend by advancing throughout much of the last decade, the glacier’s winning streak came to an end in 2006 when it began retreating alongside its icy brethren.

Soon after, in the autumn of 2007, researchers discovered a spectacularly large, pristine ice cave beneath the Nigardsbreen region of Norway’s Jostedal Glacier National Park. What they found when crawling through the cave’s five-meter opening was so magnificent that one scientist went so far as to beatify the grotto by calling it an “ice cathedral.”

Once inside, the cavernous dome measures up to eight meters in height, 30 meters deep and 20 meters wide. Its water and ice formations appear in deep crystalline blues, while the ceiling is punctuated by large icicles. Due to the literally fluid nature of the ice, the cave’s appearance is constantly changing.

Experts have attributed its unparalleled formation as an bi-product of glacial melting resulting from a steadily warming climate. Huge amounts of water melting from the glacier continue to erode the its innermost surfaces. The lagoon within the grotto simultaneously accumulates the runoff, while encouraging further melting as it ever-so-slightly warms the air trapped within the cave.
