Langjökull Glacier with Hagavatn Lake and the twilight in the b
Langjökull (Icelandic for "long glacier") is the second largest ice cap in Iceland (953 km2), after Vatnajökull. It is situated in the west of the Icelandic interior or Highlands of Iceland
Its volume is 195 km³ and the ice is up to 580 m (1,900 ft) thick. The highest point of the ice cap (at Baldjökull at the northern end of Langjökull) is about 1,450 m (4,760 ft) above sea level. In the past, the largest recorded surface area was in 1840.
Langjökull is shrinking quite fast, and some researchers believe that it will disappear in about 150 years if climate change continues at its recent pace.
