The Urdok Glacier is found in the eastern Karakoram along the Shaksgam Valley or Trans-Karakoram Tract.
In the west and south, the glacier is framed by Gasherbrum I (8,068 m), Sia Kangri (7,422 m) and Urdok I (7,250 m).
Runoff from the Urdok Glacier ultimately flows into the Shaksgam River.
The Urdok Glacier is largely covered by rock debris, which slows snowmelt.
[5] The Urdok Glacier has been known to exhibit "ice sails", a geological feature that appears as a sharp ridge or spike of melting ice protruding from the glacier surface.
