Tupopdan
Tupopdan, also known as Passu Cathedral or Passu Cones, is a mountain in northern Pakistan.Description
Tupopdan is a summit in the South Ghujerab Mountains subrange of the Karakoram. The mountain is situated north of the village of Passu and the mountain is one of the most scenic sights along the Karakoram Highway. Precipitation runoff from this mountain's slopes drains into tributaries of the Hunza River. Topographic relief is significant as the north face rises 1,700 metres in, and the summit rises 3,600 metres above the Hunza River in. The first ascent of the summit was achieved on July 6, 1987, by Andy Cave and John Stevenson via the Northeast Ridge. One source claims that Tupopdan means "sun-drenched mountain", whereas another source states it is a Wakhi word meaning "hot rock" which alludes to snow shedding quickly from the south slopes in winter.Climate
Based on the Köppen climate classification, Tupopdan is located in a tundra climate zone with cold, snowy winters, and cool summers. Weather systems are forced upwards by the mountains, causing heavy precipitation in the form of rainfall and snowfall. This climate supports two unnamed glaciers descending from the north slope. The summer months offer the most favorable weather for viewing or climbing this peak.
