Orvin Mountains

The Orvin Mountains (Orvinfjella) constitute a major group of mountain ranges, extending for about 100 km between the Wohlthat Mountains and the Mühlig-Hofmann Mountains in Queen Maud Land. With its summit at 3055 m, the massive Sandeggtind Peak forms the highest point in the Conrad Mountains, a subrange of the Orvin Mountains.

Discovery and naming

Mapped by Norwegian cartographers from surveys and air photos by the Sixth Norwegian Antarctic Expedition (1956–60) and named for Anders K. Orvin, director of the Norwegian Polar Institute from 1958 to 1959.
