The Henry Islands are a group of four small islands in the western part of Henry Bay, Antarctica. They were delineated from air photos taken by U.S. Navy Operation Highjump (1946–47), and named by the Advisory Committee on Antarctic Names after Wilkes Henry, a midshipman on the sloop Vincennes during the United States Exploring Expedition (1838–42) under Lieutenant Charles Wilkes.

Henry Bay is a small bay at the eastern end of the Sabrina Coast, Antarctica, with the Henry Islands lying in its western part. The bay was delineated from aerial photographs taken by U.S. Navy Operation Highjump (1946–47), and named by the Advisory Committee on Antarctic Names for Wilkes Henry, a midshipman on the sloop Vincennes during the United States Exploring Expedition (1838–42) under Lieutenant Charles Wilkes.

Operation Highjump United States Navy operation to establish an Antarctic research base

Operation Highjump, officially titled The United States Navy Antarctic Developments Program, 1946–1947, was a United States Navy operation organized by Rear Admiral Richard E. Byrd, Jr., USN (Ret), Officer in Charge, Task Force 68, and led by Rear Admiral Richard H. Cruzen, USN, Commanding Officer, Task Force 68. Operation Highjump commenced 26 August 1946 and ended in late February 1947. Task Force 68 included 4,700 men, 13 ships, and 33 aircraft. Operation Highjump's primary mission was to establish the Antarctic research base Little America IV.

The Advisory Committee on Antarctic Names is an advisory committee of the United States Board on Geographic Names responsible for recommending names for features in Antarctica. The United States does not recognise territorial boundaries within Antarctica, so ACAN will assign names to features anywhere within the continent, in consultation with other national nomenclatural bodies where appropriate.

Adams Glacier (Wilkes Land) glacier in Antarctica

Adams Glacier, also known as John Quincy Adams Glacier, is a broad channel glacier in Wilkes Land, Antarctica which is over 20 miles (32 km) long. It debouches into the head of Vincennes Bay, just east of Hatch Islands. It was first mapped in 1955 by G.D. Blodgett from aerial photographs taken by U.S. Navy Operation Highjump (1947), and it was named by the Advisory Committee on Antarctic Names (US-ACAN) for John Quincy Adams, sixth President of the United States. Adams was instrumental while later serving as U.S. representative from Massachusetts in gaining congressional authorization of the United States Exploring Expedition (1838–42) under Lieutenant Charles Wilkes, and perpetuating the compilation and publication of the large number of scientific reports based on the work of this expedition.

It was named by Eklund for Richard J. Berkley, a geomagnetician with the US-IGY wintering party of 1957 at Wilkes Station.

First photographed from the air by U.S. Navy Operation Highjump, 1946–47, it was included in a 1957 survey of the Swain Islands by Wilkes Station personnel under Carl R. Eklund. It was named by Eklund for Lieutenant (j.g.) Donald Burnett, U.S. Navy, Military Support Unit Commander of the 1957 wintering party at Wilkes Station during the International Geophysical Year.
