Keilhaufjellet is a prominent mountain located in the Sør Rondane Mountains of Queen Maud Land, Antarctica. Situated within the Norwegian Antarctic Territory, it stands as a notable geographical feature in a region characterized by vast ice sheets and scattered nunataks.
Geography Keilhaufjellet rises to an approximate height of 2,360 meters (7,743 feet) above sea level. It is positioned roughly 2 nautical miles (3.7 km) east of Widerøefjellet, contributing to the rugged landscape of the eastern Sør Rondane range. The mountain's geology is typical of the East Antarctic Craton, consisting predominantly of ancient metamorphic and igneous rocks, often partially exposed from beneath the continental ice sheet.
History and Naming The mountain was first mapped by Norwegian cartographers in 1957, utilizing air photographs taken during the Lars Christensen Expedition of 1936–37. It was named Keilhaufjellet in honor of Baltazar Mathias Keilhau (1797–1858), a distinguished Norwegian geologist and professor at the Royal Frederick University (now the University of Oslo). Keilhau was a pioneering figure in Norwegian geology, renowned for his extensive geological surveys and contributions to the understanding of Scandinavia's geological structure. The naming reflects Norway's historical connections to Antarctic exploration and scientific research.
Significance As part of the Sør Rondane Mountains, Keilhaufjellet serves as a landmark in an area frequently traversed by scientific expeditions, particularly those focused on glaciology, geology, and meteorology. Its location in Queen Maud Land, a region under Norwegian claim, underscores the long-standing Norwegian involvement in Antarctic research and territorial interests.
