This is a moulin in the Jakobshavn Glacier of Greenland. The Jakobshavn Glacier is the fastest moving glacier on our planet with speeds of up to 30m/day.
In the summer, the increased temperatures cause melt water to form lakes and rivers on the surface of the ice. The water formed flows into deep vertical shafts in the ice called moulins. Scientists are unsure of where the water flowing into these moulins ends up, but it has been speculated that it may be falling to the base of the glacier. Water at the base of the glacier lubricates its motion and enhances its speed. It is believed that eventually the water drains into the the Arctic Sea.
This is one of the most photographed places in Greenland, and it’s easy to see why! The stunning contrast between blue and white makes for an eye-catching image!
The canyon is usually between 30m and 40m deep, and has formed from melt-water from a lake on the ice draining away and eventually disappearing into a Moulin- A moulin described as one of the largest ever found. (For our previous post on Moulins head here; http://on.fb.me/Tf4Aow)
