Ben Lomond (Waikato)
Obsidian veins at Ben Lomond
|Elevation||744 m (2,441 ft)|
|Location||North Island, New Zealand|
|Last eruption||100,000 years|
Ben Lomond erupted about 100,000 years ago, producing two lava lobes that flowed around 3.5 kilometres south and southwest from a vent about one kilometre south of Poihipi Road. Much of the lava formed grey banded obsidian as it cooled. Crystalline rhyolite and pumice were also produced.
