Greenland's sole entry on the UNESCO World Heritage Site list is the Ilulissat Icefjord. Located just south of the small town of Ilulissat, the fjord runs from Jakobshavn Glacier in the east 40km (25mi) west to empty into Disko Bay. Jakobshavn Glacier is the most productive glacier in the northern hemisphere, flowing at a rate of 20-35m (66-105ft) daily.
The icebergs that are calved off from the glacier are sometimes so large that they are stuck in the fjord for years until they are broken up into smaller pieces. It's believed that one of these large icebergs calved off and shrunk in size before eventually being struck by the Titanic, causing the ship to sink.
