The Champagne Pool, Waiotapu, New Zealand
It's where Maori warriors came to soothe their aching muscles and spirits. The famous Champagne Pool of Waiotapu in New Zealand forms part of a series of springs said to be sacred. It was formed 900 years ago (that's like yesterday in geological terms) during a hydrothermal eruption.
What gives it the unique colour? Metallic compounds present in the rock surrounding the pool. But the name comes from the constant bubbling thanks to the constant release of carbon dioxide (CO2 – just like a glass of bubbling champagne.)
