The Shackleton Glacier originates in the East Antarctic Ice Sheet and flows northeast between Dismal Buttress to the northwest and Roberts Massif to the southeast.
It is joined from the right (east) by Zaneveld Glacier, which also originates in the ice sheet.
Further north it is joined from the right by the Logie Glacier, which flows west through the Cumulus Hills.
Flowing north, the Shackleton Glacier is joined from the left (west) by the Gallup Glacier and the Baldwin Glacier and from the right (east) by McGregor Glacier just past Eckins Nunatak.[2]
The Swithinbank Moraine extends north from Matador Mountain along the west side of the Shackleton Glacier to the Gemini Nunataks.
It crosses the mouths of the Gallup, Baldwin, Mincey and Field glaciers, left tributaries of the Shackleton Glacier.[2][3]
Past Lockhart Ridge the Shackleton Glacier is joined from the right by the Yeats Glacier.[2]
The glacier flows north through the Queen Maud Mountains, with the Anderson Heights to its west and the Cathedral Peaks to its east.
Below the Gemini nunataks the Gerasimou Glacier and Forman Glacier enter from the west before the mouth of the Shackleton Glacier.
From the right (east) the Shackleton Glacier is fed by the Dick Glacier and McCuistion Glacier.
It is joined by the Massam Glacier at its mouth.
The Barrett Glacier enters the Ross Ice Shelf just east of the Shackleton Glacier.[3]
