Austin Glacier flows northbound into Beckmann Fjord. Finally, the farthest east side of the Bay of Isles is marked by Cape Wilson. Islands The Bay of Isles is named for its numerous islands, many of which are named after local birds: Albatross Island (albatross) Crescent Island Invisible Island Mollyhawk Island (mollyhawk) Skua Island (skua) Petrel Island (petrel) Prion Island (prion) Tern Island (tern) Charting and naming of features Cape Buller was discovered and named in 1775 by a British expedition under James Cook. Markham Point was named on a 1912 chart by J. Innes Wilson. Beckmann Fjord, Bellingshausen Point, Brunonia Glacier, Cape Wilson, Grace Glacier, Lucas Glacier, Sea Leopard Fjord, and Sunset Fjord were charted in 1912-13 by Robert Cushman Murphy, who visited South Georgia in the brig Daisy. Beckmann Fjord was named for Captain Beckmann, master gunner of the whaler Don Ernesto, who lost his life in a whaling accident in December 1912. Bellingshausen Point was named for Admiral Thaddeus Bellingshausen. Murphy named Brunonia Glacier for his alma mater, Brown University, using a Latinized version of the name. Cape Wilson was named for American President Woodrow Wilson. Grace Glacier was named for Murphy's wife, Grace Barstow Murphy. He named Lucas Glacier for Frederic Augustus Lucas, then-director of the American Museum of Natural History. Sunset Fjord was named because he could see the sunset directly behind the fjord from his anchorage in the Bay of Isles. Ample Bay, Barlas Bank, Camp Bay, Jock Point, and Luck Point were charted and named by Discovery Investigations (DI) personnel between 1928 and 1930. Ample Bay was first sketched but not named by Murphy. Barlas Bank was named after William Barlas, the British representative at Deception Island and the South Shetland Islands. Camp Bay was named for a temporary camp set up on its southern shore. Jock Point wa named after Petty Officer J. "Jock" Purvis, a member of the DI hydrographic survey team. The name Koppervik was in use prior to 1930, probably by Norwegian whalers operating at South Georgia. The names Austin Glacier, Breakwater Point, Ram Head, and Shag Point first appear on a 1931 British Admiralty chart. The South Georgia Survey (SGS) of 1951-1957 has been responsible for selecting several names in and around the Bay of Isles. The SGS named Rosita Harbour after the company's whaling ship Rosita, which anchored in this bay, rejecting the alternate name Allardyce Harbour. In
