Tucker Glacier

Tucker Glacier (-72.53333°N, 169.25°W) is a major valley glacier of Victoria Land, Antarctica, about 90 nmi long, flowing southeast between the Admiralty Mountains and the Victory Mountains to the Ross Sea. There is a snow saddle at the glacier's head, just west of Homerun Range, from which the Ebbe Glacier flows northwestward.

Exploration and naming
Explored by New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1957–58, and named by them after Tucker Inlet, the ice-filled coastal indentation at the mouth of this glacier named by Captain James Clark Ross in 1841.

Geography
The upper reaches of the Tucker Glacier south of the Homerun Range saddle with the Greenwell Glacier and Jutland Glacier, in the Lillie Glacier basin. The Tucker Glacier is fed by the Rastorfer Glacier from the left (north) and then by the Leander Glacier after it has been joined by the Church Glacier. South of the McGregor Range the Man-O-War Glacier enters from the northeast, combined with the Freimanis Glacier from the east. Tributaries of the Man-O-War Glacier include the Massey Glacier, Deming Glacier and Fitch Glacier. Tributaries of the Tucker Glacier from the Admiralty Mountains to the east below the Freimants Glacier include the Tocci Glacier, Helman Glacier, Tyler Glacier, Staircase Glacier, Kelly Glacier and Towles Glacier.

To the south of the Pemmican Step, the Montecchi Glacier enters from the west. South of that the Pearl Harbor Glacier enters the Tucker Glacier from the west, flowing to the north of the Cartographers Range. The Muller Glacier is an upper tributary of the Pearl Harbor Glacier, both forming in the Millen Range. Lower down the Lensen Glacier and DeWald Glacier join the Pearl Harbor Glacier from the south, while the Midway Glacier, McKellar Glacier and Summers Glacier join the Pearl Harbor Glacier from the north.

The Trafalgar Glacier is a major contributor from the west, flowing to the south of the Cartographers Range. Tributaries of the Trafalgar Glacier from the south include the Osuga Glacier, Trainer Glacier after its confuence with the Gruendler Glacier, Rudolph Glacier, Stafford Glacier and Coral Sea Glacier. Tributaries of the Trafalgar Glacier from the north include the Wood Glacier, Croll Glacier, Hearfield Glacier and Coulson Glacier. To the west of its mouth the glacier receives the Coral Sea Glacier, Elder Glacier and Bowers Glacier from the south. At its mouth the glacier flows into the Tucker Inlet. The Whitehall Glacier, with its tributary the Baker Glacier, also flow into the Tucker Inlet from the west.
