Rumdoodle Peak  Rumdoodle Peak, elevation 875 m ASL, is a small but prominent mountain in the north-western part of the North Masson Range in Antarctica, near Mawson Station. It was named, around 1960, after the previously fictitious peak featured in the book "The Ascent of Rum Doodle". There is a small hut at the base (altitude 498m ASL), sleeping 5 people, and two permanently frozen lakes alongside, named Rumdoodle Lake and Lassitude Lake.
