Morgan Inlet
Morgan Inlet is an ice-filled inlet about 18 nautical miles (33 km) long, with two branches, indenting the east end of Thurston Island, Antarctica, between Lofgren Peninsula and Tierney Peninsula.[1] The south side of the larger north arm of the inlet is an area of icy rock exposures called the King Cliffs.[2] The east extremity of the wedge-shaped promontory between Lofgren Peninsula and Tierney Peninsula is called Ryan Point.[3]
These features were discovered in helicopter flights from the U.S. Navy Bellingshausen Sea Expedition in February 1960, and were named by the Advisory Committee on Antarctic Names. The inlet was named for Lieutenant Commander Joseph R. Morgan, U.S. Navy, a hydrographic and oceanographic officer of U.S. Navy Task Force 43 during this expedition.[1] The cliffs were named for geologist Charles E. King, a member of the Ellsworth Land Survey which worked at the cliffs in the 1968–69 season.[2] The point is named after A.E. Ryan, Chief Photographer's Mate in the Eastern Group of U.S. Navy Operation Highjump, which obtained aerial photographs of Thurston Island and adjacent coastal areas, 1946–47.[3]
