330 Squadron discovered a large hole in the glacier Blåmannsisen in Nordland when they flew over the area as a part of  a military excercise trip.

– It is not normal that they are so big. The ones forming during the summer, are usually between 20 and 30 centimeters in width,  Atle Nesje, a professor at the Geological Institute of the University of Bergen, says to TV 2.

Kjetil Wiik at 330 Squadron says this hole seemed to be between 15 and 20 meters in diameter, and went very far down the ice.

Nesje thinks the hole is a melt hole formed when the melt water has been present on the surface of glacier. This is relatively common in Norwegian glaciers.

– Due to the pressure it has melted itself down into glacier. When a hole appears in the glacier, it has emptied itself of the water,  Nesje says, and informs that the water usually works its way through the ice until it reaches the bottom.

– It could be anything from a few tens of meters to 100 meters down. It depends on how thick the ice is at that point, says Nesje.

330 Squadron discovered the hole when they flew over Blåmannsisen Monday. This glacier is  the fifth largest in Norway’s and is in the municipality of Fauske and Sørfold.
