Much of the Coppermine Peninsula in the west of the island is made up by a perched strandflat surface that was at sea level in the past.[3]
Captain Richard Fildes may have named Robert Island for his brig Robert.[4] Fildes was sealing in the South Shetlands in 1821–1822 until ice destroyed his vessel in March 1822. Fildes Strait is named for him.
