North Island Volcanic Plateau
From Wikipedia, the free encyclopedia
The North Island Volcanic Plateau (often called the Central Plateau and occasionally the Waimarino Plateau) is a volcanic plateau covering much of the central North Island of New Zealand. Extensive ignimbrite sheets spread east and west of the Taupo Volcanic Zone, from the three active peaks of Mount Tongariro, Mount Ngauruhoe, and Mount Ruapehu in the south, past the dormant supervolcano, Lake Taupo, and beyond Rotorua to the north.
To the west of the three southern volcanoes, the land is rough forested hill country, and the north, close to Lake Taupo, is fertile and undulating. To the east, however, the landscape is quite different. The barren, ash-laden soils of the region and harsh alpine climate leave the high land to the east largely bare and unprofitable, capable of growing only scrubby plants. This area is known as the Rangipo Desert. To the east of this lies further rough hill country, notably the Kaimanawa Ranges.
The entire area bounded by the towns of Taihape in the south, Ohakune in the west, and Taupo in the north, with Turangi just south of Taupo and by the Kaweka Ranges in the east is above 300 metres, with a considerable proportion of it more than 800 metres above sea level.
The majority of the population of the area lives close to the shores of Lake Taupo, with some smaller settlements to the east of the volcanoes. These make their living largely through tourism, including skiing in the winter season, or by forestry in the plateau's northeast, which includes the Kaingaroa Forest.
The Rangipo region is largely uninhabited. It is used by the New Zealand Army, based at Waiouru in the south, and by the Rangipo prison farm in the north.
