Mount Thomson is a mountain in New Zealand.
Mount Thomson is set on the crest or Main Divide of the Southern Alps and is situated on the boundary shared by the West Coast and Canterbury Regions of South Island. This peak is located west-northwest of Mount Cook Village and set on the boundary shared by Aoraki / Mount Cook National Park and Westland Tai Poutini National Park. Precipitation runoff from the mountain drains west into the headwaters of the Douglas River and east to the Hooker River. Topographic relief is significant as the summit rises above the Mueller Glacier in two kilometres. The nearest higher neighbour is Mount Sefton, three kilometres to the north-northeast. The mountain's toponym was applied by Gerhard Mueller to honour John Turnbull Thomson (1821âÂÂ1884), Chief Surveyor of Otago who later became the first Surveyor General of New Zealand. This mountain's toponym has been officially approved by the New Zealand Geographic Board.
Climbing routes with the first ascents:
Based on the Köppen climate classification, Mount Thomson is located in a marine west coast (Cfb) climate zone, with a subpolar oceanic climate (Cfc) 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 (orographic lift), causing moisture to drop in the form of rain or snow. This climate supports the Douglas, Frind, Donne, and Fyfe glaciers surrounding the peak. The months of December through February offer the most favourable weather for viewing or climbing this peak.
