K2 is the second-highest mountain on Earth. It is located in the Karakoram segment of the Himalayan range, on the border between the Gilgit-Baltistan region of the Pakistani-occupied Northern Areas and the Taxkorgan Tajik Autonomous County of Xinjiang, China.
Chinese authorities officially refer to K2 as Qogir; Simplified Chinese: 乔戈里峰; Traditional Chinese: 喬戈里峰; Pinyin: Qiáogēlǐ Fēng. This name is derived from Chogori, "a synthetic name made up by Western explorers early in the 20th century from two Balti words, chhogo ('big') and ri ('mountain')." Other names include Mount Godwin-Austen, Lamba Pahar ("Tall Mountain" in Urdu), Dapsang, Kechu or Ketu (both derived from "K2").
