There’s only a handful of natural travertine rock formations𝔞 in the entire world, but after 1886 there was was one less. In that year in New Zealand’s Rotorua/Bay of Plenty area, the terraced hot springs wonderland known to Pākehā New Zealanders as the “Pink and White Terraces”𝔟 (Ōtukapuarangi and Te Tarata) were obliterated from sight in a massive eruption from nearby Mt Tarawera (Māori: “burnt spear/peaks”)𝔠.

Fallout from the volcano’s eruption blanketed some 15,000 sq kms of countryside with ash in the air travelling as far away as Christchurch, over 800 km to the south. The explosion of volcanic craters reduced Lake Rotomahana (“warm lake”) to mud and ash. The deafening noise and lightning of the dome volcano exploding caused some in Auckland to think that Russian warships were attacking the city [‘The Night Tarawera awoke’, New Zealand Geo, www.nzgeo.com]. The human casualties were almost all Māori, about 120 people died, as well as 10 Māori settlements destroyed or buried.

19th century tourist attraction
Nature’s violent removal of the Rotomahana travertines brought an abrupt end to a lucrative little 19th century tourism earner for the local region. Artist Charles Blomfield who painted the two terraces on multiple occasions was an eye witness to the tourist boom, observing groups of “moneyed people” bathing in the hot springs𝔡 while their lunches of potatoes and koura were cooking in the boiling pools (NZ Geo)𝔢. Village residents benefitted—some Māori guides netted incomes of up to £4,000 a year—but the First Nation community also copped the downside from the economic boost, rising illness and rampant alcoholism [‘Tarawera Te Maunga Tapu’, Rotorua Museum, www.rotoruamuseum.co.nz].
Lost and found?
For 120 years New Zealanders thought that all trace of the iconic terraces—the two largest known formations of silica sinter on earth—had vanished. Scientific curiosity in recent decades has speculated whether the terraces has been destroyed altogether or perhaps permanently entombed. Recently, Geologists, drawing on Ferdinand von Hochstetter’s 1859 topographic and geological survey of Lake Rotomahana as a primary source, believe they have found traces of the lost White Terraces in the naturally-restored, crater-enlarged lake [‘A natural wonder lost to a volcano has been rediscovered’, Robin Wylie, BBC, 28-Apr -2016, www.bbc.com]. The terraces are thought submerged under sediment and 50-60 m of lake water.

Right in the firing line of Mt Tarawera when it exploded in 1886 was the tiny village of Te Wairoa and its inhabitants the Tuhourangi people. Engulfed and obliterated by the eruption, it became known as the “Buried Village” of Te Wairoa. These days it has brought back tourism to the area. The excavated village is New Zealand’s most popular archaeological site.

Postscript: the Rotomahana travertines are destroyed but is at least one terraced hydro-thermal springs in the North Island remains. Wairakei Terraces, situated 90 km south of Tarawera in Taupō, is a smaller version of the Pink and White Terraces. This commercial operation is a combination of the synthetic (man-made geyser) and the natural (pink, blue and white silica steps).
🔻Pamukkale, Turkey
🌋 one of the most outstanding examples of travertine formations on the planet is the “Cotton Castle” of Pamukkale in eastern Turkey, with its glistening white-terraced geo-thermal springs sharing the site with the ruins of a Greco-Roman city Hierapolis, making it a world-class tourist magnet. Other extant travertines include Badab-e-Surt in Iran, Mammoth Hot Springs in Wyoming, USA, and Egerszalok in Hungary.

𝔡 the actual numbers of Europeans who visited New Zealand’s version of the “8th Wonder of the World” was not as high as might be thought, owing to the terraces not being easily accessible – from the closest settlement Rotorua it was a trek over hills by horse or buggy followed by a canoe trip and the last section on foot [New Zealand’s Pink and White Terraces’, (Tourism NSW), www.media.newzealand.com]
𝔢 English novelist Anthony Trollope was one of the European ‘celebs’ who fronted up to bathe in the pools and sleep in a whare (Māori hut) next to the terraces (NZ Geo). Trollope found nothing like its waters in the world – “you strike your chest against it, it is soft to the touch, you press yourself against it and it is smooth” [Australia and New Zealand, (Vol.II, 1873]
