The Pink Terrace, or Te Otukapuarangi in Māori, and the White Terrace, also known as Te Tarata, were natural wonders of New Zealand. They were reportedly the largest silica sinter deposits on earth. Until recently, they were lost and thought destroyed in the 1886 eruption of Mount Tarawera, while new hydrothermal features formed to the south-west i.e. Waimangu Volcanic Rift Valley.
The Pink and White Terraces were formed by upwelling geothermal springs containing a cocktail of silica-saturated, near-neutral pH chloride water. These two world-famous springs were part of a group of hot springs and geysers, chiefly along an easterly ridge named Pinnacle Ridge. The main tourist attractions included Ngahapu, Ruakiwi, Te Tekapo, Waikanapanapa, Whatapoho, Ngawana, Koingo and Whakaehu.
The Pink and the White Terrace springs were around 1,200 metres apart. The White Terrace was at the north-east end of Lake Rotomahana and faced west to north west at the entrance to the Kaiwaka Channel. Te Tarata descended to the lake edge around 25 metres below. The Pink Terrace lay four fifths of the way down the lake on the western shore, facing east to south-east.
