Hallett Station () in the
Admiralty Mountains as seen from Cape Hallett 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. New Zealander
Robert B. Thomson was scientific leader at the station in 1960. He later became officer-in-charge at
Wilkes Station in 1962, and deputy leader at
Scott Base in 1963-64.
Thomson Peak, in the Mirabito Range,
Victoria Land, was named after him. Hallett Station was manned permanently until 1964, when there was a major fire, and was then used as a summer only base until 1973. A project has been started to
remediate the site by removing hazardous materials such as fuel, and oil stored in several large tanks. 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. Of these, only McMurdo and Admundsen-Scott are still being operated by 2022. ==Antarctic Specially Protected Area==
