Geologist and author Bruce Hayward will lead this 3-4 km walk along Tamaki Estuary's Rotary Coastal Walkway.

Along the way you will see:

  • an accumulation of black lignites in ancient swamps
  • volcanic ash deposits from the Mangakino Caldera Volcano eruption about 1 million years ago. Some are from New Zealand's largest eruption - one of largest known on earth
  • fossilised remains of forests that grew in the area at the time of the eruptions
  • fossilised freshwater wetland vegetation from the Panmure Basin Volcano

    eruption about 25,000 years ago.
