Description

Dome is located 108 kilometres (67 mi) northwest of Christchurch in Arthur's Pass National Park in the South Island. It is part of the Polar Range of the Southern Alps.^[3] Precipitation runoff from the mountain's slopes drains to the Waimakariri River via Red Beech Stream, Douglas Stream, and Edwards River. Topographic relief is significant as the summit rises 1,345 metres (4,413 feet) above the Waimakariri River Valley in four kilometres, and 1,000 metres (3,281 feet) above Red Beech Stream in 1.5 kilometres. The nearest higher peak is Mount Wilson, 5.2 kilometres to the north.^[2]

Climate

Based on the Köppen climate classification, Dome is located in a marine west coast (Cfb) climate zone.^[6] Prevailing westerly winds blow moist air from the Tasman Sea onto the mountains, where the air is forced upwards by the mountains (orographic lift), causing moisture to drop in the form of rain or snow. The months of December through February offer the most favourable weather for viewing or climbing this peak.^[7]
