A team of geologists and marine scientists are preparing to take to the waters of Lake Rotomahana, hoping to discover that part of the Pink and White Terraces still exist.

The group, from GNS, Waikato University and Woods Hole Oceanographic Institute, are planning a series of underwater explorations next year to map the lake floor and to gain a better understanding of what happened to the famous geological feature once considered the eighth wonder of the world.
