Joyce Glacier
Joyce Glacier () is a glacier in Antarctica, immediately north of Péwé Peak, draining from the névé northeast of Catacomb Hill and terminating up-valley (west) of the snout of Garwood Glacier, which would have been a tributary to it in times of more intense glaciation. It was named by the New Zealand Blue Glacier party (1956–57) after Ernest Joyce Ernest Edward Mills Joyce AM ( – 2 May 1940) was a Royal Naval seaman and explorer who participated in four Antarctic expeditions during the Heroic Age of Antarctic Exploration, in the early 20th century. He served under both Robert Falcon ..., a member of British Antarctic expeditions of 1901–04, 1907–09 and 1914–17.

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Péwé Peak
Péwé Peak () is a bedrock peak, high, composed of granite and topped with a dolerite sill. The peak is immediately south of Joyce Glacier and is surrounded by glacial ice except on the south side. It was named by the Advisory Committee on Antarctic Names for Troy L. Péwé, a glacial geologist with U.S. Navy Operation Deep Freeze, 1957–58, who personally explored this peak as well as adjacent portions of Victoria Land Victoria Land is a region in eastern Antarctica which fronts the western side of the Ross Sea and the Ross Ice Shelf, extending southward from about 70°30'S to 78°00'S, and westward from the Ross Sea to the edge of the Antarctic Plateau.

Névé
Névé is a young, granular type of snow which has been partially melted, refrozen and compacted, yet precedes the form of ice. This type of snow is associated with glacier formation through the process of ''nivation''. Névé that survives a full season of ablation turns into firn, which is both older and slightly denser. Firn eventually becomes glacial ice – the long-lived, compacted ice that glaciers are composed of. Glacier formation can take days to years depending on freeze-thaw factors. Névé is annually observed in skiing slopes, and is generally disliked as an icy falling zone. Névé has a minimum density of 500 kg/m3, which is roughly half of the density of liquid water at 1 atm. Névé can also refer to the alpine Alpine may refer to any mountainous region. It may also refer to: Places Europe * Alps, a European mountain range ** Alpine states, which overlap with the European range Australia * Alpine, New South Wales, a Northern Village * Alpine Nati ...

Catacomb Hill
Catacomb Hill () is a prominent rock peak, high, on the ridge that borders the east side of the head of Blue Glacier, in Victoria Land. The New Zealand Blue Glacier Party of the Commonwealth Trans-Antarctic Expedition (1956–58) established a survey station on its summit in December 1957. They gave it this descriptive name from the spectacular cavernous weathering occurring in the granite of the peak, suggestive of catacombs Catacombs are man-made subterranean passageways for religious practice. Any chamber used as a burial place is a catacomb, although the word is most commonly associated with the Roman Empire. Etymology and history The first place to be referred ....

Garwood Glacier
Garwood Glacier () is a glacier occupying the northwest part of Garwood Valley, in Victoria Land, Antarctica. It was first mapped by the British National Antarctic Expedition (1901–04), but was not named until 1911, when Thomas Griffith Taylor of the British Antarctic Expedition, 1910–13, named it for Edmund J. Garwood, professor of geology and mineralogy at the University of London. Projection Peak rises above its head at the most southeastern point of Hobbs Ridge.

Blue Glacier (Antarctica)
Blue Glacier is a large glacier which flows into Bowers Piedmont Glacier about south of New Harbour, in Victoria Land, Antarctica. Robbins Hill is the East-most rock unit on the north side of the terminus of the glacier. It was discovered by the British National Antarctic Expedition under Robert Falcon Scott Captain Robert Falcon Scott, , (6 June 1868 – c. 29 March 1912) was a British Royal Navy officer and explorer who led two expeditions to the Antarctic regions: the ''Discovery'' expedition of 1901–1904 and the ill-fated ''Terra Nov ..., 1901–04, who gave it this name because of its clear blue ice at the time of discovery.

Ernest Joyce
Ernest Edward Mills Joyce AM ( – 2 May 1940) was a Royal Naval seaman and explorer who participated in four Antarctic expeditions during the Heroic Age of Antarctic Exploration, in the early 20th century. He served under both Robert Falcon Scott and Ernest Shackleton. As a member of the Ross Sea party in Shackleton's Imperial Trans-Antarctic Expedition, Joyce earned an Albert Medal for his actions in bringing the stricken party to safety, after a traumatic journey on the Great Ice Barrier. He was awarded the Polar Medal with four bars, one of only two men to be so honoured, the other being his contemporary, Frank Wild. Joyce came from a humble seafaring background and began his naval career as a boy seaman in 1891. His Antarctic experiences began 10 years later, when he joined Scott's Discovery Expedition as an Able Seaman. In 1907 Shackleton recruited Joyce to take charge of dogs and sledges on the Nimrod Expedition. Subsequently, Joyce was engaged in a similar capacity fo ...

British Antarctic
The British Antarctic Territory (BAT) is a sector of Antarctica claimed by the United Kingdom as one of its 14 British Overseas Territory, British Overseas Territories, of which it is by far the largest by area. It comprises the region south of 60th parallel south, 60°S latitude and between longitudes and , forming a wedge shape that extends to the South Pole, overlapped by the Antarctic claims of Argentina (Argentine Antarctica) and Chile (Chilean Antarctic Territory). The Territory was formed on 3 March 1962, although the UK's claim to this portion of the Antarctic dates back to letters patent of 1908 and 1917. The area now covered by the Territory includes three regions which, before 1962, were administered by the British as separate dependencies of the Falkland Islands: Graham Land, the South Orkney Islands, and the South Shetland Islands. The United Kingdom's claim to the region has been suspended since the Antarctic Treaty came into force in 1961, Article 4 of ...
