Lyall Islands (70°41′00″S 167°20′00″E / 70.6833°S 167.3333°E) is a group of four islands, Unger Island, Surgeon Island, Novosad Island and Hughes Island, lying just outside the entrance to Yule Bay, Victoria Land, Antarctica.[1]
Exploration and naming
[edit]The Lyall Islands were discovered by Captain James Clark Ross, 1841, who named the group for David Lyall (1817–1895), MD, RN, FLS, Assistant Surgeon on the Terror. In keeping with this, the United States Advisory Committee on Antarctic Names (US-ACAN) has named some of the individual islands and nearby features for surgeons who have worked in Antarctica.[1]
Location
[edit]
The Lyall Islands are in the Pacific Ocean to the north of Tapsell Foreland and east of Yule Bay and the Davis Ice Piedmont. From west to east they are Unger Island, Surgeon Island, Novosad Island and Hughes Island.[2]

Mapped by USGS from surveys and United States Navy air photos, 1960-63. The toponym conforms to other names in the island group which, along with Cape Hooker, have been named after surgeons who have worked in Antarctica. Named by the US-ACAN.[4]
