Bizarre landscapes
Karst in Stone: karst landscapes in New Zealand by Jill Kenny & Bruce Hayward
Geological Society of New Zealand guidebook 13, $12 Reviewed by SIMON NATHAN
Karst landscapes are some of the most unusual in New Zealand – distinguished by steep cliffs, sinkholes, caves, fluted rocks, and disappearing streams. Peter Jackson is fascinated by karst landscapes (although he may not use that technical term), and they appear many times in the Lord of the Rings trilogy. They have also been a favourite subject for many artists, including Leo Bensemann.
Karst is caused by the action of water which has corroded easily dissolvable rocks such as limestone and marble. This booklet gives an overview of karst landscapes in New Zealand, and discusses how they form and the need for them to be treasured.
