Gunnbjørn Fjeld is thehighest mountain inGreenland, north of theArctic Circle, and the highest point in North America not on the mainland. It is anunatak, a rocky peak protruding throughglacial ice. Gunnbjørn Fjeld is ranked 9th bytopographic isolation.
Gunnbjørn Fjeld is located in theWatkins Range, an area ofnunataks on the east coast, which contains several other summits above 3,500 metres.[1] Its height is often given as 3,700 metres (12,139 ft), although figures vary slightly.
This is higher thanSnæfellsjökull, 530.2 kilometers away on the west coast ofSnæfellsnes onIceland.[2]
Normal straight light rays do not allow one to simultaneously see Gunnbjørn Fjeld and Snæfellsjökull. However, arctic mirages allow seeing long distances by refracting (bending) the light. This effect is caused by a thermal density gradient in the atmosphere. It has been suggested that mutual visibility may exist underhillingar effect orArctic mirage conditions.[3]
Gunnbjørn Fjeld was first climbed on 16 August 1935 byAugustine Courtauld,Jack Longland,Ebbe Munck andLawrence Wager. It is named afterGunnbjörn Ulfsson, the first European to have sighted Greenland.
The peak rises in an uninhabited part of the eastern coast of Greenland. The mountain is climbed infrequently due to its remote location. Access is often done with helicopter or ski-equipped plane (normally from Iceland).
