On 16 October 1958, a Douglas C-124C Globemaster II (52-1017) of the USAF crashed into a 3200-foot mountain near Cape Hallett Bay while maneuvering, killing 7 of the 13 occupants.

[1] The cape was the location of a joint scientific base, Hallett Station, between the United States and New Zealand during the International Geophysical Year of 1957, and was manned permanently until 1964, when there was a major fire.

Hallett Station was one of seven bases that the United States built for the IGY, which also included McMurdo, Wilkes, Admundsen-Scott, Ellsworth, Byrd, and Little America.

Animals found at the site include, as well as four species of mites and three of springtails, breeding colonies of south polar skuas and Adélie penguins.

[3] A large Adélie penguin colony occupies Seabee Hook, on the west side of Hallett Peninsula between Moubray Bay and Edisto Inlet.
