Balls Pyramid — a unique uninhabited volcanic island located in the Tasman Sea, near Australia's Lord Howe Island.

This 562-meter-high rock is awe-inspiring: with a base area of just 200 square meters, it's considered the tallest volcanic stack on Earth!

🌋 Did you know? Balls Pyramid is the remnant of a shield volcano that erupted beneath the sea about 7 million years ago. It's also home to the Lord Howe Island stick insect, thought to be extinct until its rediscovery on the pyramid in 2001! 🦗
