The Pleiades are located at the crest of the Transantarctic Mountains, - away from the coast of Lady Newnes Bay, Ross Sea. The volcanoes are located between Evans Neve and the beginning of Mariner Glacier, which drains Evans Neve southeastwards towards the Ross Sea. The volcanic group is named after the Pleiades star cluster in the constellation Taurus; the name was assigned to them by the New Zealand Geological Survey Antarctic Expedition.
