Foley, of the United States Geological Survey, Reston, Virginia, a computer specialist and team member of the Glaciological and Coastal-Change Maps of Antarctica Project.
Gibbs Glacier is a glacier, 15 nautical miles (28 km) long, flowing southeast into the northern part of Mercator Ice Piedmont on the east side of the Antarctic Peninsula. This feature together with Neny Glacier, which flows northwest, occupy a transverse depression between Mercator Ice Piedmont and Neny Fjord on the west side of the Antarctic Peninsula. Gibbs Glacier was photographed from the air and first mapped by the United States Antarctic Service, 1939–41, and the Ronne Antarctic Research Expedition, 1947–48. It was named by the UK Antarctic Place-Names Committee for Peter M. Gibbs of the Falkland Islands Dependencies Survey, a surveyor at Horseshoe Island, 1957, and leader at Stonington Island, 1958, who was responsible for the first ground survey of the glacier.
Goff Glacier is a broad glacier flowing from Parker Peak into the head of Koether Inlet on the north side of Thurston Island, Antarctica. It was named by the Advisory Committee on Antarctic Names after Lieutenant Robert G. Goff, co-pilot of PBM Mariner aircraft in the Eastern Group of U.S. Navy Operation Highjump, which obtained aerial photographs of Thurston Island and adjacent coastal areas, 1946–47.
Long Glacier is a glacier about 8 nautical miles long in the southeastern part of Thurston Island, Antarctica. It flows south to the Abbot Ice Shelf, 14 nautical miles (26 km) west of Harrison Nunatak.

Marck Glacier is a glacier flowing into the southwestern extremity of Cadwalader Inlet on the north side of Thurston Island, Antarctica. It was named by the Advisory Committee on Antarctic Names after Aviation Machinist's Mate George H. Marck, an aircrewman in the Eastern Group of U.S. Navy Operation Highjump, which obtained aerial photographs of Thurston Island and adjacent coastal areas in the summer of 1946–47.
Keuken Rock is a large insular rock lying off the Vestfold Hills, Antarctica, about 1.4 nautical miles (2.6 km) southwest of Barratt Island. It was mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition, 1936–37, and was named by the Antarctic Names Committee of Australia for J. Keuken, a weather observer at Davis Station in 1959.
