Description
Geothermal pool, New Zealand. Geothermal pools form in areas where volcanic activity causes hot water to rise up from beneath the Earth's surface. The hot water is often brightly coloured, due to minerals dissolved in it. The pool in the background is the Champagne Pool, and the waters (at 75 degrees Celsius) are spilling out over the surrounding silica terrace (foreground), which is called the 'Artist's Palette'. The minerals causing the bright colours here include sulphides of arsenic, antimony and mercury, and small amounts of gold and silver. These features are part of the geothermal area of Waiotapu, 25 kilometres south of Rotorua, on New Zealand's North Island.
