Of the roughly 150 islands that comprise the Haida Gwaii archipelago, the two largest islands are Graham to the north and Moresby to the south. Not to be confused with the much smaller,
6.5 square km Moresby Island in the Gulf Islands group, this Moresby is British Columbia's third largest island at over 2,000 square km: only Graham Island and Vancouver Island are larger.2
Moresby Island was named so in 1853 by Prevost, commander of the HMS Virago, and Moresby's son-in-law.2
