Mount Foweraker is located northwest of
Christchurch in
Arthur's Pass National Park in the
South Island. It is part of the Polar Range of the
Southern Alps. Precipitation runoff from the mountain's slopes drains to the
Waimakariri River.
Topographic relief is significant as the summit rises above the Waimakariri River Valley in three kilometres, and above Sudden Valley Stream in 1.5 kilometres. The nearest higher peak is
Dome, 2.7 kilometres to the west. The mountain's toponym honours
Charles Ethelbert Foweraker (1886–1964), a New Zealand botanist, forester, and academic. His focus on mountain plants and rainforests in New Zealand contributed to the understanding of South Island vegetation. He spent a considerable amount of time based at the
Cass Field Station (8.5 km southeast of peak) where he taught and researched in the area surrounding the field station and this then-unnamed mountain. The mountain's toponym has been officially approved by the
New Zealand Geographic Board. ==Climate==
