About
The Tama Lakes (Māori: Ngā puna a Tama) are two crater lakes in New Zealand's Tongariro National Park. They fill two (Upper and Lower Tama) of a series of explosion craters on the Tama Saddle between Mount Ruapehu and Mount Ngaruahoe (a main Mount Tongariro vent). Geologically the deep magma source and depth of basement are not usual for vents in the area.
