Mount Adams, New Zealand
From Wikipedia, the free encyclopedia
Mount Adams is a mountain in the West Coast region of New Zealand's South Island. It is roughly 19 km south of Harihari and reaches 2,208 m (7,244 feet) in height.[1]
On 6 October 1999, a landslide from Mount Adams deposited 10-15 million cubic metres of rock in the Poerua River, creating a natural dam that broke six days later. Fears of major damage did not turn into reality when the dam was breached, though significant quantities of coarse gravel were deposited downstream and the river's path was changed in places.[2]
