, in recognition of the support given to the expedition by its citizens. A paper summarizing the Joint Services expedition of 1984–1985 describes the island as "notoriously inhospitable" and states that there is evidence for only six visits between the discovery in 1898 and 1984. Members of the expedition overwintered there in 1984–1985, and made the first ascent of Mount Parry.
