Strictly speaking the Taupō caldera complex is just one part of the volcanic plateau covering much of central North Island, which also includes ash deserts, crater lakes, lava plateaus, the Ōkataina caldera complex, and the Tongariro Volcanic Centre. It's very active - Mount Ngauruhoe for example, is a beautifully cone-shaped stratovolcano 2,291 m tall, and less than 2500 years old. In fact the plateau is currently the most frequently active and productive area of silicic volcanism on Earth.

You might also recognise it as Mt Doom from the LOTR films.

In 1974 a champion skier (and presumed lunatic) by the name of Jean-Claude Killy skied down the side of Ngauruhoe you can see here, as part of a promotional campaign for Moët & Chandon. He hit well over 100kph. And he was doing this while the volcano was erupting.

Mount Ruapehu, south of Ngauruhoe, is also active, but is also the site of the North Island's only glaciers and major ski resorts. The eruptions have certainly been deadly, but most of the fatalities occured on Christmas Eve 1953 when the tephra dam constraining the crater lake collapsed and sent a landslide of mud, rock and water down the Whangaehu River minutes before an express train came through.

In 2007 two climbers nearly drowned on top of the mountain, when they took shelter in an alpine hut 600m from the crater, and an underwater eruption in the crater lake drove a surge 2km from the crater. Luckily for them the floor gave way and the water drained into the seismometer vault beneath the hut. One of the mountaineers still had a leg crushed by boulders in the debris.

East of the volcanoes is Te Onetapu, also known as the Rangipo Desert. It gets a decent amount of rain and occasionally heavy snow, but doesn't hold onto any of it because the entire area is thickly buried in unconsolidated ash and other volcanic debris and it immeadiately drains away.

It also doesn't have any trees to speak of, because the supervolcano eruptions at Lake Taupo 26,000 years ago carbonised every living thing in the area, including the seeds, and the ecosystem is still recovering. Forests on the western side of Ruapehu were partly shielded by the height of the volcano, and survived.

While @purrdence spent a few hours at the military museum south of the desert, I drove back up the road and went looking for insects. Some were abundant, like the Tiger Beetles, but they amazingly frustrating to photograph, taking off and being whisked away by the wind the moment I came near. Or being chased off, sometimes in flight, by the aforementioned ravenous beetles. At least the plants stayed in one spot, and the bumblebee was enthralled by the blue paintjob of the car.
