Mount Joyce is a prominent, dome-shaped mountain, 1,830 m, standing 8 miles (13 km) northwest of Mount Howard in the Prince Albert Mountains, Victoria Land, on the south side of David Glacier. It 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 Discovery expedition, 1901-04. Joyce was also with the Ross Sea Party of Shackleton's Imperial Trans-Antarctic Expedition, 1914-17.

Geology

Mount Joyce, along with nearby nunataks, such as the Trio Nunataks, represent 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 Mt Joyce only three major dolerite sills are observed, with two thin interleaving seams of Beacon sediments ^[1]
