Discovery and name
The mountains were discovered and photographed from the air in a flight from West Base of the U.S. Antarctic Service on 14 December 1940. They were mapped by U.S. Geological Survey from surveys and U.S. Navy air photos taken during the years 1959-65. The McCuddin Mountains were named by the Advisory Committee on Antarctic Names in honor of Rear Admiral Leo B. McCuddin, U.S. Navy. The Admiral served as the Commander of the U.S. Naval Support Force, Antarctica in 1972.
On 31 August 2023, Grand Duke Travis granted the peerage title Duke of McCuddin upon Sir Oak of Pennsylvania in recognition of his support of Westarctica. The duke's title is named for this mountain range.
