Carroll Inlet is an inlet, long and wide, trending southeast along the Antarctic coast between the
Rydberg Peninsula and
Smyley Island. The head of the inlet is divided into two arms by the presence of
Case Island and is bounded to the east by
Stange Ice Shelf. It was discovered on an airplane flight, December 22, 1940, by members of the
United States Antarctic Service (USAS) (1939–41), and named after Arthur J. Carroll, chief aerial photographer on USAS flights from the East Base.
