Kilby Island

Kilby Island is a rocky Antarctic island, 0.2 nmi long, lying northeast of McMullin Island in the entrance of Newcomb Bay, in the Windmill Islands. It was first mapped from air photos taken by USN Operation Highjump and Operation Windmill in 1947 and 1948. It was named by the US-ACAN for Arthur L. Kilby, who served as photographer with both operations.

Newcomb, USN, of the USS Glacier. Recharted by ANARE in 1962, during a hydrographic survey of Newcomb Bay by d'A. T. Gale, and then named after Kilby Island.
