Radian Glacier
Radian Glacier is a glacier on the east side of the Royal Society Range, descending from a high cirque just southeast of Mount Rucker and flowing east toward Walcott Glacier. In the measurements made of this glacier by the Victoria University of Wellington Antarctic Expedition , one of the survey angles, by chance, was exactly one radian, and the glacier came to be referred to by this term.
Radian Ridge is a ridge named in association with Radian Glacier.
