Mount Alba


Mount Alba is a mountain in New Zealand.

Description

Mount Alba is set on the crest or Main Divide of the Southern Alps and is situated on the common boundary shared by Otago and West Coast Regions of South Island. This remote peak is located west-southwest of the city of Christchurch and is set in Mount Aspiring National Park. Precipitation runoff from the mountain drains east to the Wilkin River via Siberia and Newland streams, whereas the west slope drains into the Te Naihi River. Topographic relief is significant as the summit rises nearly above Crucible Lake in one kilometre, and over above the Siberia Valley in three kilometres. The nearest higher peak is Mount Castor, 10 km to the southwest.

Etymology

The origin of the mountain's name is not documented, but it is recorded as a Latin word which can mean white. Mount Alba could thus be construed as "Mount White" which would be analogous to Mont Blanc of the French Alps. The Māori name for this mountain is "Kahukura" which means multicoloured or rainbow, and in mythology Kāhukura is the atua of rainbows.

Climbing

Climbing routes on Mount Alba:
Based on the Köppen climate classification, Mount Alba is located in a marine west coast climate zone, with a subpolar oceanic climate at the summit. Prevailing westerly winds blow moist air from the Tasman Sea onto the mountains, where the air is forced upward by the mountains, causing moisture to drop in the form of rain or snow. This climate supports the Axius Glacier on this mountain's west slope and small unnamed glaciers on the other surrounding slopes. The months of December through February offer the most favourable weather for viewing or climbing this peak.
