Ball’s Pyramid

Ball’s Pyramid is an erosional remnant of a shield volcano and caldera that formed about 7 million years ago. Ball’s Pyramid is 20 kilometres (12 mi) southeast of Lord Howe Island in the Pacific Ocean. It is 562 metres (1,844 ft) high, while measuring only 1,100 metres (3,600 ft) in length and 300 metres (980 ft) across, making it the tallest volcanic stack in the world. Ball’s Pyramid is part of the Lord Howe Island Marine Park.

The pyramid was named after Lieutenant Henry Lidgbird Ball, who discovered it in 1788 at the same time he discovered Lord Howe Island. The first person to go ashore is believed to have been Henry Wilkinson in 1882, who was a geologist at the New South Wales Department of Mines.
