Ilulissat Icefjord

 From Unesco World Heritage Convention https://whc.unesco.org/en/list/1149/ :

"Located on the west coast of Greenland, 250 km north of the Arctic Circle, Greenland’s Ilulissat Icefjord is the sea mouth of Sermeq Kujalleq, one of the few glaciers through which the Greenland ice cap reaches the sea. Sermeq Kujalleq is one of the fastest and most active glaciers in the world. It annually calves over 35 km3 of ice, i.e. 10% of the production of all Greenland calf ice and more than any other glacier outside Antarctica. "
