Ball's Pyramid is an uninhabited islet in the Pacific Ocean located 20 kilometres (12 mi) southeast of Lord Howe Island. The steep rocky basalt outcrop is the eroded plug of a shield volcano and caldera that formed 6.4 million years ago.^[2]^[3] It is 572 metres (1,877 ft) high, while measuring 1,100 metres (3,609 ft) in length and only 300 metres (984 ft) across, making it the tallest volcanic stack in the world.^[4]

Ball's Pyramid, which is part of Australia's Lord Howe Island Marine Park, is positioned in the centre of a submarine shelf surrounded by rough seas, which makes any approach difficult.^[2]
