Admiralty Glacier (Danish : Admiralty Gletscher) is a glacier in Queen Louise Land, northeastern Greenland. [1] Administratively it belongs to the Northeast Greenland National Park.
The glacier was mapped during the 1952–54 British North Greenland expedition led by Commander James Simpson. It was named after the British Admiralty in order to commemorate the assistance given to the expedition by the Royal Navy. [2]
The Admiralty Glacier is one of the main glaciers in northern Queen Louise Land. It flows from the Greenland Ice Sheet from west to east the first 20 km (12 mi), slightly bending to the north of Trefork Lake and flowing roughly northeastwards. The Ad Astra Ice Cap lies to the east of its lower stretch. The glacier has its terminus in the Støvdal valley at the Britannia Lake, near the southern end of the Britannia Glacier. [2]
The structure of the cliffs on either side of Admiralty Glacier was examined by the British North Greenland expedition geologists. Expedition member and glaciologist Hal Lister wrote the following from a campsite at the glacier itself:
The striking rock-colours of reds, browns and blacks were edged with snow that was rose-coloured in the fading sun. Ice lakes on the glacier looked beautifully blue, but were very slippery and, in the lakes that filled little basins at the foot of the valley walls, fallen stones looked ominously cold and imprisoned... The whole atmosphere was of gaunt grandeur, terrific and awesome beneath the jagged, pinnacled cliffs. [3]
North Ice was a research station of the British North Greenland Expedition on the inland ice of Greenland. The coordinates of the station were 78°04′N38°29′W, at an altitude of 2,341 metres (7,680 ft) above sea level. The British North Greenland Expedition had its main base camp in Britannia Lake, Queen Louise Land. It was led by Commander James Simpson RN. The station recorded a temperature of −66.1 °C (−87.0 °F) on 9 January 1954, which made it the lowest temperature ever recorded in North America up until that time. It was superseded by an observation of −69.6 °C (−93.3 °F) at the Greenland Ice Sheet on 22 December 1991. The name of the station contrasts to the former British South Ice station in Antarctica.
The British North Greenland expedition was a British scientific mission, led by Commander James Simpson RN, which lasted from July 1952 to August 1954. A total of 30 men took part, though not all stayed for both years.

The Denmark expedition, also known as the Denmark Expedition to Greenland's Northeast Coast, and as the Danmark Expedition after the ship, was an expedition to the northeast of Greenland in 1906–1908. Despite being overshadowed by the death in tragic circumstances of the main exploration team, including three of the expedition's leading members: Ludvig Mylius-Erichsen (1872–1907), Niels Peter Høeg Hagen (1877–1907) and Jørgen Brønlund (1877–1907), the Denmark expedition was not a failure. It achieved its main cartographic objectives and succeeded in exploring the vast region, drawing accurate charts of formerly unexplored coastlines and fjords, naming numerous geographic features, and gathering a wealth of scientific data.
