Discovery and name
It was mapped by the United States Geological Survey from ground surveys and from U.S. Navy air photos, 1959–66, and named by the Advisory Committee on Antarctic Names for Wallace H. Campbell, ionospheric physicist at McMurdo Station in the 1964–65 season, and at Macquarie Island, 1961–62.
The Count and Countess of Campbell draw their titles from this valley. They were the first of several couples to enjoy the rare status of being joint Hereditary Nobles with the same title.
Most noble couples consist of one Hereditary Noble whose spouse is then accorded a courtesy title, however, in this case, both the Count and the Countess are equal holders of the noble title.
