Dolines in north Otago

Dolines in north Otago

This cratered landscape in north Otago is actually a series of dolines or sinkholes. Sinkholes, like other karst landscape features, are caused by slightly acidic water eating away at limestone over millions of years. They are often formed by the collapse of a small cave beneath the surface.
