Story: Conservation – a history

Quarried volcanic cones

Quarried volcanic cones

During his visit to New Zealand in 1858–59, geologist Ferdinand Hochstetter prepared a detailed map of the volcanic cones and lava flows around Auckland, incorporating information supplied by Charles Heaphy. Aggregate from cones and lava flows was prized for roads, footpaths and other construction projects. Many cones were quarried away, with major changes to the landscape. The overlay to the map illustrates the extent of the quarrying over 140 years.
