Lord Howe Island is one of only four island groups in the world that possesses World Heritage status.
This is all thanks to its 'remarkable volcanic geology, its exceptional range of ecosystems, its rare collection of plants, birds and marine life...and last, though by no means least, its exceptional natural beauty.'
Starting approximately 6.9 million years ago, over a period of 500,000 years, constant eruptions produced a volcanic island estimated to be 40 times Lord Howe Island’s current land mass. Mt. Lidgbird, Mt. Gower and Balls Pyramid are believed to be the remnants of a caldera wall that rose 1200 m. above sea level.
Lord Howe Island’s present day size is the product of marine erosion, producing its spectacular sheer black basalt cliffs. Balls Pyramid to the south represents the near complete erosion of a volcanic island, with only a sliver of basalt rock remaining that rises 562 m. skyward from the ocean surface. It's the world's tallest sea stack!
