The Great Wall of Sermeq Kujalleq
Ilulissat glacier, or Sermeq Kujalleq in Greenlandic (which sounds way cooler), is a large outlet glacier in western Greenland. It produces around 10% of all Greenland icebergs. Some 35 billion tonnes of icebergs calve off and pass out of the fjord every year. Icebergs breaking from the glacier are often so large (up to a kilometer in height) that they are too tall to float down the fjord and lie stuck on the bottom of its shallower areas, sometimes for years, until they are broken up by the force of the glacier and icebergs further up the fjord. This makes the fjord white with ice. The edge of the glacier towers hundreds of meters over the ice-filled water. It really looks like a great wall.
