Moraine Fjord is an inlet 3.5 miles (6 km) long with a reef (a terminal moraine) extending across its entrance, forming the west head of Cumberland East Bay, South Georgia. Charted by the Swedish Antarctic Expedition under Nordenskjold, 1901-04, who so named it because of the large glacial moraine at its entrance.
