[1] Casey Inlet is on the Wilkins Coast of Palmer Land on the Antarctic Peninsula, beside the Weddell Sea to the east.

[2] Casey Inlet was photographed from the air by Sir Hubert Wilkins in 1928, Lincoln Ellsworth in 1935 and the United States Antarctic Service (USAS) in 1940.

A black, rock cape rising to 250 metres (820 ft) high and forming the north side of the entrance to Casey Inlet.

Discovered by Sir Hubert Wilkins in a flight on December 20, 1928, and named by him for George E. Miller of Detroit, Michigan.

A large isolated mountain mass, surmounted by three separate peaks, the highest 1,220 metres (4,000 ft) high.

It stands between Poseidon Pass and Athene Glacier, 10 nautical miles (19 km; 12 mi) west-northwest of Miller Point.

A glacier 6 nautical miles (11 km; 6.9 mi) wide, flowing east into Casey Inlet.

Correlation of aerial photographs taken by Lincoln Ellsworth in 1935 and preliminary reports of the British Graham Land expedition (BGLE), 1934-37, led W. L. G. Joerg to interpret this glacier to be what Wilkins named "Casey Channel".

The name by the UK Antarctic Place-Names Committee (UK-APC) is suggested by the fin-like shape of the feature.
