Geothermal pool, New Zealand
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. This is the edge of the Champagne Pool, where the waters (at 75 degrees Celsius) are spilling out over the surrounding silica terrace. The minerals causing the bright colours here include sulphides of arsenic, antimony and mercury, and small amounts of gold and silver. This feature is part of the geothermal area of Waiotapu, 25 kilometres south of Rotorua, on New Zealand's North Island.
