# Mount Joyce

Mount Joyce (75°36′S 160°49′E﻿ / ﻿75.600°S 160.817°E﻿ / -75.600; 160.817﻿ (Mount Joyce)) is a prominent, dome-shaped mountain, 1,830 metres (6,000 ft) high, standing 8 nautical miles (15 km) northwest of Mount Howard in the Prince Albert Mountains of Victoria Land, Antarctica.

## Exploration and name

Mount Joyce was first mapped by the British Antarctic Expedition, 1907–09, which named it for Ernest Joyce who was in charge of general stores, dogs, sledges, and zoological collections with the expedition and who had earlier been with the British National Antarctic Expedition, 1901–04. Joyce was also with the Ross Sea party of Shackleton's Imperial Trans-Antarctic Expedition, 1914–17.

## Location

Mount Joyce is south of David Cauldron in the David Glacier and east of Hollingsworth Glacier. The Ricker Hills lie to the west. Nearby features include Burrage Dome to the northeast, Mount Mallis, Mount Howard, Mount Billing and Mount Bowen to the southeast, and Crash Nunatak and Ford Peak to the southwest.

## Geology

Mount Joyce, along with nearby nunataks, such as the Trio Nunataks, represents the remnants of a tableland of the Jurassic Ferrar Group, which consists of Kirkpatrick lavas and Ferrar dolerite sills, alternating with rafts of sandstone of the Paleozoic and Mesozoic Beacon Supergroup. The strata dip about 1-2 degrees (at most) to the west. On Mount Joyce only three major dolerite sills are observed, with two thin interleaving seams of Beacon sediments.
