The glacier is among the most active glaciers on earth! How is a glacier active, you ask? Well, it moves, of course. This glacier moves 130 feet a day. The geography of the land where the glacier drains creates a very narrow stream, resulting in Sermeq Kujalleq being one of the fastest moving glaciers in the world.
Its annual calving makes for 10% of the all Greenland calf ice and more than any other glacier outside Antarctica. But don't let that despair you- calving is indeed a natural process in all glaciers. Unnatural sped-up erosion of a glacier is called disintegration, and you can read more about the difference between the two here. 
The only way to see the Sermeq Kujalleq Glacier itself is with a scenic flight- you can't reach it on foot. But you can explore the downstream from afar and enjoy the frequent calving, as Sahai does: "I love coming there at around midnight, sitting down with a thermos full of hot coffee and listening to the icebergs calving while they are making their way into the ocean."
Ice-breaking off the glacier is usually very large and can reach up to 3,300 ft in height. These lumps are too tall to float down the stream. They just remain static in the shallow, sometimes even for years until they're broken down by natural wear.
