Tengi Ragi Tau, also known as Agole, is a mountain in Nepal.
Tengi Ragi Tau is a summit on the western boundary of Sagarmatha National Park in the Nepalese Himalayas. It is set on the border shared by the Dolakha District and the Solukhumbu District. Precipitation runoff from the mountain's east slope drains to the Bhotekoshi River, whereas the west slope drains to the Tamakoshi River via RolwÃÂliá¹ Khola. Topographic relief is significant as the summit rises 1,400 metres (4,593 ft) above the Drolambao Glacier in , and 2,560 metres (8,400 ft) above Dig Tsho Lake in . The first ascent of the summit was achieved on December 4, 2002, by Koichi Ezaki, Ruchia Takahashi, Pasang Tamang, and Tul Bahadur Tamang via the southeast face. The second ascent, first via the west face, was made on October 16, 2019, by Tino Villanueva and Alan Rousseau via a route they named Release the Kraken.
Based on the Köppen climate classification, Tengi Ragi Tau is located in a tundra climate zone with cold, snowy winters, and cool summers. Weather systems coming off the Bay of Bengal are forced upwards by the Himalaya mountains (orographic lift), causing heavy precipitation in the form of rainfall and snowfall. Mid-June through early-August is the monsoon season. The months of April, May, September, October, and November offer the most favorable weather for viewing or climbing this peak.
