The Pink and White Terraces, beautiful silica formations that were a great New Zealand tourist attraction in the 19th century, were destroyed in the 1886 Tarawera Eruption.
At least we thought they were. The Pink Terrace has been discovered, or at least part of it has, on the floor of Lake Rotomahana.
At 60 metres deep, the terrace isn’t easily accessible. But it’s nice to know it’s still there.
