Where are the 'Grimsley Peaks' situated?

The Grimsley Peaks, whose coordinates are: 66°34′S 53°40′E, are five linear peaks just south of Stor Hanakken Mountain in the Napier Mountains of Enderby Land, Antarctica.

Enderby Land was first documented in western and eastern literature in February 1831 by John Biscoe aboard the whaling brig 'Tula', and named after the Enderby Brothers of London, the ship's owners who encouraged their captains to combine exploration with sealing.

Subject to the constraints of the 'Antarctic Treaty System', the longest-held nation-state claimant rights in the territory is Australia, being a large part of its claimed Australian Antarctic Territory up to various high latitudes towards the South Pole.

The Grimsley Peaks were mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition of 1936–37.

They were remapped from air photos taken by Australian National Antarctic Research Expeditions in 1956 and were named by the Antarctic Names Committee of Australia for S.W. Grimsley, a technical officer (involved in studying the ionosphere) at Wilkes Station in 1961.
