Skua Island is an island immediately northeast of Prion Island in the entrance to the Bay of Isles, South Georgia. Charted in 1912-13 by Robert Cushman Murphy, American naturalist aboard the brig Daisy. Surveyed in 1929-30 by DI personnel and named in association with Albatross Island, Prion Island and other natural history names given in the Bay of Isles by Murphy in 1912–13.[1]
Rescue Rock (-54°N -51°W) is a submerged rock marked by breakers, 0.6 nautical miles (1.1 km) northeast of Skua Island. It was charted in 1930 by DI survey personnel. So named because a whale catcher passing near this rock sighted a flag on Skua Island, eventually leading to the rescue of the survey party at Camp Bay where their vessel had run aground.[2]
