Ball's Pyramid, Australia


 

Ball's Pyramid is an erosional remnant of a shield volcano and caldera that formed about 7 million years ago. It lies 20 kilometers southeast of Lord Howe Island in the Pacific Ocean. It is 562 meters high, while measuring only 1,100 meters in length and 300 meters across, making it the tallest volcanic stack in the world.Ball's Pyramid is part of the Lord Howe Island Marine Park in Australia.

The pyramid was named after Lieutenant Henry Lidgbird Ball, who discovered it in 1788 on the same trip as when 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.
