Glacial erosion then became prominent, and
large u-shaped valleys, moraines, hanging valleys,
cirques, arêtes, and other glacial landforms were
created as the mountains were eroded

Volcanism still continued in this time, however
glacial erosion was the more influential process.
Further evidence of this is Proto-Ngauruhoe
(meaning “First” Ngauruhoe), which was eroded
down by glaciers carving into the soft ash-cinder
cone, leaving a much smaller mountain behind

20,000 Years ago saw a major change in climate:
temperatures dropped and the permanent
snowline fell to 1500m above sea level (a.s.l.)

15,000 YBP the ice began to melt and retreat, and
the glaciers became rivers as the snowline lifted.

An example of this type of erosion can be seen in
the Mangatepopo Valley, a U-shaped valley.
Pinnacle ridge on Ruapehu is also product of
glacial erosion
