It is located within the southern part of Alexander Island, west of Palmer Land in Antarctica, at approximately 72°S latitude and 68°W longitude.

The northern side of this lake is bounded by the Saturn Glacier, which flows east into George VI Sound.

The lake lies next to and southeast of Citadel Bastion, a pre-eminent mountain on Alexander Island.

Eventually, it retreated from the local area of Hodgson Lake and left it covered only by perennial ice sometime before 11,000 years ago.
