The Pink Terraces in New Zealand were found 125 years after apparently being destroyed by a volcano.
Scientists spotted the coloured steps in sonar images captured by robots beneath Lake Rotomahana on the North Island.
They were about to call off their search when the discovery was made. The 70m-long (230ft) and 60mwide Terraces were thought to have been wrecked when the nearby Mount Tarawera erupted in 1886, killing 100 people.

The terraces, located on the edges of Lake Rotomahana near Rotorua, were New Zealand's most famous tourist attraction. They were attracting tourists from Europe in the early 1880s, when New Zealand was still relatively inaccessible and when passage took several months by sailing ship.
The Pink and White Terraces were the only New Zealand example of travertine terrace formations; they were formed by geothermally heated water containing large amounts of siliceous sinter regularly spouting from two geysers located beside Lake Rotomahana and cascading down a hill slope, leaving thick pink and white silica deposits that formed terraces enclosing pools of water.[3] The White Terraces were the larger and more beautiful formation, covering 3 hectares and descending 30 metres, while the Pink Terraces were where people went to bathe.

...In June of 1886, while volcanic activity rocked nearby Mount Tarawera, molten rock oozed upward beneath Lake Rotomahana, triggering steam explosions that blasted numerous holes in the lake bottom. The resulting rock-and-sediment-filled debris blocked the stream flowing from the lake, raising water levels about 100 meters and dramatically expanding the lake's size, says Cornel de Ronde, a geologist with GNS Science, a government-owned research institute based in Lower Hutt, New Zealand.
Now, de Ronde and his colleagues, including researchers from Woods Hole Oceanographic Institution (WHOI) in Massachusetts, have probed the lake with an autonomous underwater vehicle (AUV) and found parts of the Pink Terraces. During the 2-week-long field study, the 2-meter-long AUV—essentially a sensor-filled, camera-equipped, programmable torpedo—scanned the lakebed with sonar. It detected long, crescent-shaped features at a depth of about 60 meters in an area where the terraces were known to be located...

My grandfather did a landscape painting of the Pink and White Terraces just before the eruption! I always wished my Mum still had it...

So, it's good news that some have been found!

Hopefully we see a lot more stories coming out of NZ soon. A lot of interesting stuff here.
