Mangaweka Mudstone cliffs
Dramatic cliffs of 2.8-million-year-old deep-marine Mangweka Mudstone form an imposing backdrop along middle reaches of the Rangitikei River. Bands of hard concretions, much the same as those at the nearby Whitecliffs Boulders, protrude from the cliff face. The cliffs also contain thin volcanic ash layers from large eruptions in the then-active Tauranga-Kaimai Volcanic Centre, and thin sandstone beds that represent submarine landslide and storm deposits.
