Kaimanawa Forest Park Geology & Natural History

The ranges of Kaimanawa Forest Park are composed of uplifted fractured greywacke, (coarse-grained sedimentary sandstone) that formed 300 - 145 million years ago.

Volcanic materials from various Taupo eruptions blanket some of the ridges and terraces, (Ignimbrite Saddle on the Middle Range is a good example) and are the basis of most of the park’s soils.
