Fimbulheimen is a mountain range in Queen Maud Land, Antarctica. It stretches from Jutulstraumen by 1° west of Carsten Borchgrevink Ice at 18° east, about 200 km from the ice edge. Fimbulheimen is thus between Maudheim Plateau and Sør-Rondane. Dronning Maud's highest mountain, Jøkulkyrkja (elevation 3148 m), is located in Mühlig-Hofmann Mountains in Fimbulheimen. The name comes from Fimbulvetr, the harsh winter immediately preceding Ragnarok in Norse mythology. A number of smaller ranges and mountain areas constitutes Fimbulheimen, from west to east: The Norwegian research station Troll is located by Jutulsessen Mountain west in Fimbulheimen, while the ornithological field station Tor is about 100 km further east at Svarthamaren Mountain in Mühlig-Hofmann Mountains. Large parts of the area were mapped by the Norwegian Antarctic Expedition 1956-60. The Norwegian Polar Institute has published twelve map sheets of Fimbulheimen in scale 1:250 000.
