Dismal Mountains  Dismal Mountains is a group of nunataks about southwest of Rayner Peak in Antarctica. They were photographed from ANARE (Australian National Antarctic Research Expeditions) aircraft in 1956, and surveyed by G.A. Knuckey during a dog-sledge journey from Amundsen Bay to Mawson Station in December 1958. They are so named because the mountains are frequently shrouded in clouds.
