Thurston Island is separated from the mainland by Peacock Sound, which is occupied by the western portion of Abbot Ice Shelf.[2] It lies off the Eights Coast.[3] Bellingshausen Sea lies the east and Amundsen Sea to the west.[4][5] Sherman Island, Carpenter Island and Dustin Island in Seraph Bay lie to the south of Thurston Island. The Walker Mountains form the spine of the island. Peaks in that range include, from west to east, Landfall Peak, Mount Lopez, Mount Caldwell, Mount Kazukaitis, Mount Simpson, Mount Noxon, Mount Leech, Mount Hubbard, Smith Peak, Mount Borgesen, Guy Peaks, Mount Hawthorne, Mount Bramhall, Zuhn Bluff and Parker Peak.[2]
The northwest side of the island consists of a series of capes, peninsulas and inlets. From west to east they include Cape Flying Fish, Cape Petersen, Williams Island, Jones Peninsula, Dyer Point, Cape Davies, Hughes Peninsula, Henry Inlet, Tinglof Peninsula, Wagoner Inlet, Starr Peninsula, Potaka Inlet, Kearns Peninsula, Peale Inlet, Glacier Bight, Noville Peninsula, Porters Pinnacles and Mount Palmer.[2] Features of the north of the island include Sikorski Glacier, Mount Feury, Frankenfield Glacier, Mulroy Island, Black Crag, Pelter Glacier, Murphy Inlet, Linsley Peninsula, Ball Peninsula, Edwards Peninsula, Mount Bubier, Koether Inlet, Evans Peninsula, Cape Walden and Cape Braathen.[2]

Thurston Island island was discovered by Rear Admiral Richard E. Byrd and members of the United States Antarctic Service (USAS) in a flight from the Bear on 27 February 1940. Byrd named it for W.

Originally charted as a peninsula, the feature was found to be an island by the USN Bellingshausen Sea Expedition in February 1960.[1]
On 30 December 1946, Thurston Island was the site of Antarctica's first fatal plane crash. A Martin PBM-5 Mariner (59098) of the US Navy with the Byrd expedition hit a ridge and burned on the island, killing 3 of the 9 occupants. The 6 survivors were rescued 13 days later.[6]
