Mount D'Archiac is a 2,875-metre-elevation (9,432-foot) mountain in the Canterbury Region of New Zealand.

Description

[edit]

Mount D'Archiac is the highest peak in the Two Thumb Range which is a subrange of the Southern Alps. It is situated 180 kilometres (112 mi) west of the city of Christchurch and is set on the eastern boundary of Aoraki / Mount Cook National Park in the Canterbury Region of South Island.[5] Precipitation runoff from the mountain drains east to the Havelock River and west to the Godley River. Topographic relief is significant as the summit rises 1,475 metres (4,839 feet) above the Godley Glacier in two kilometres. The first ascent of the summit was made in March 1910 by Jim Dennistoun, Laurence Earle, and Jack Clarke via the East Ridge and Forbes Glacier.[3] The nearest higher peak is Mount Annan, 20 km to the west-southwest.[2]

Etymology

[edit]

The mountain was named by Julius von Haast to honour Vicomte d'Archiac (1802–1868), a French geologist and professor of palaeontology at the Paris Museum of Natural History.[6] The Māori name for this mountain is "Kāhuikaupeka" which means "assembly of river heads" as the mountain is the source for several rivers and streams.[5][7]

Climate

[edit]

Based on the Köppen climate classification, Mount D'Archiac is located in a marine west coast (Cfb) climate zone, with a tundra climate at the summit.[17] Prevailing westerly winds blow moist air from the Tasman Sea onto the mountains, where the air is forced upward by the mountains (orographic lift), causing moisture to drop in the form of rain or snow. This climate supports the Dennistoun, Trident, FitzGerald, Separation, and South Forbes glaciers on this mountain's slopes. The months of December through February offer the most favourable weather for viewing or climbing this peak.[18]
