When you think of glaciers, you don't exactly think of them as being speedy.
But checking out the fastest glacier in the world can be a dangerous expedition.

Sermeq Kujalleq, also known by Jakobshavn Glacier, in Greenland's Ilulissat Icefjord travels an average of 40 metres a day, sending icebergs out to sea where they can threaten many a ship.
For those on land, its movements create tsunami waves that can come out of nowhere, and aggressive signs warn people to stay off the beach if they don't want to risk 'death and serious injury', according to Atlas Obscura.
The icefjord is also a loud place - popping air escaping from the ice and icebergs crashing into each other in the small spaces make quite a bang.
Some even say that the iceberg that sunk the Titanic might have been born out of Sermeq's womb, seeing as the glacier produces about 10% of all of Greenland's icebergs.

The glacier is also very popular in science - it has been studied for over 250 years and helped make advancements in the science of climate change and how glaciers in general work and is thus declared a World Heritage Site.
Besides being speedy, Sermeq was also once one of the fastest shrinking ice masses in the world - in the last two years it has started thickening again due to cooling waters, reported NBC.
However, scientists believe worse melting is still in store for this King of Glaciers, painting a bleak picture for our oceans.

How can you see Sermeq Kujalleq?
The easiest to get to the town of Ilulissat is by flying from Iceland's international airport Reykjavík–Keflavík Airport with either Air Greenland or Air Iceland Connect.
From there, there are a few ways to see Ilulissat Icefjord and Sermeq - you can either do a helicopter trip to see it by air, go sailing through the maze of giant icebergs or hike through the icefields on the Blue Route Trail or the raised path to Sermermiut.
The best time to visit is from February to late April, when the day and night hours are more normal, unless you want to see the icefjord in the midnight sun, which takes place from April to August.
