A cover from Greenland, featuring a stamp with an UNESCO natural site - the Ilulissat Icefjord (6.00 stamp, on the right).
Ilulissat Icefjord is a fjord in western Greenland, declared a UNESCO World Heritage Site in 2004. Ilulissat Icefjord is one of the few places where the Greenland ice sheet meets the sea, in the Sermeq Kujalleq glacier. This is one of the most active glaciers in the world, which annually calves over 35 cubic kilometres (8.4 cu mi) of ice. It has been studied for over 250 years, providing insight into icecap glaciology and climate change.
