Many features within the bay have been individually charted and named by various Antarctic expeditions and surveys.
Western coast is in
King Edward Cove, on the western shore of Cumberland East Bay The western headland of the bay is Sappho Point on Thatcher Peninsula. Working south along the west coast, the next major feature is
King Edward Cove, approximately southwest. South of that, the glacial plain
Hestesletten extends from inland out to the coast.
Moraine Fjord forms the west head of the bay, separated from it by
Greene Peninsula.
Nordenskjöld Glacier flows into the head of the main portion of Cumberland East Bay.
Eastern coast The bay is defined to the east by Barff Peninsula, culminating in Barff Point to the north. Along that coast, the small cove Sandebugten forms the west end of
Reindeer Valley. The name "Sandebugten" appears on a 1929
British Admiralty chart but probably was applied earlier by Norwegian whalers operating from South Georgia. ==References==
