Description
Putahi is a 381 m (1,250 ft) high rhyolite dome, in the Kaikohe-Bay of Islands volcanic field in New Zealand.
"In the last half-million years, 12 small basalt volcanoes have erupted in the southern part of the field (Smith
et al. 1993), forming a cluster of scoria cones around Kaikohe. Te Puke volcano erupted in the hills
behind Waitangi 100 000 years ago, forming three small cones and a spreading flow that now underlies
Waitangi golf course and treaty grounds. The youngest volcano is Tauanui, 10 km south of Kaikohe, which
60 000 years ago produced a high scoria cone and a lava flow that flowed 19 km down the Taheke Valley
towards the Hokianga Harbour. The field includes a small rhyolite dome (Putahi), overlooking Lake
Omapere. The field should still be considered dormant, and not extinct."
