Mount Avalanche is a 2,606-metre-elevation (8,550-foot) mountain in New Zealand.

Description

Mount Avalanche is located four kilometres south of Mount Aspiring / Tititea in the Southern Alps. The summit is set on the boundary shared by the Otago and West Coast Regions of the South Island. It is also within Mount Aspiring National Park which is part of the Te Wahipounamu UNESCO World Heritage Site. Precipitation runoff from the mountain's slopes drains to the Matukituki River. Topographic relief is significant as the summit rises 2,000 metres (6,562 feet) above the Kitchener River in three kilometres. The nearest higher neighbour is Rob Roy Peak, 3.6 kilometres to the south.[2]

Climate

Based on the Köppen climate classification, Mount Avalanche is located in a marine west coast climate zone, with a subpolar oceanic climate (Cfc) at the summit.[5] Prevailing westerly winds blow moist air from the Tasman Sea onto the mountain, where the air is forced upwards by the mountains (orographic lift), causing moisture to drop in the form of rain and snow. This climate supports the Bonar, Hood, Avalanche, and Maud Francis glaciers on the mountain's slopes. The months of December through February offer the most favourable weather for viewing or climbing this peak.[6]
