evidence: The Trans-Karakoram Tract (Hindi: शक्स्गम्, Shaksgam;Chinese: 喀喇昆仑走廊; pinyin: Kālǎkūnlún zǒuláng), also known as Shaksgam or the Shaksgam Tract, is an area of more than 9,900 km2 (3,822 sq mi) along both sides of the Shaksgam River and extending up to the Kunlun range wherein are the Kukalang, Yangi, Kilian, Sanju-la and Hindutash border passes, entirely administered by the People's Republic of China as a part of Kargilik County and Taxkorgan Tajik Autonomous County in the Kashgar Prefecture of Xinjiang Autonomous Region, but claimed by Pakistan until 1963.[1] It is claimed by India as part of the state of Jammu and Kashmir. [...] The tract is one of the most inhospitable areas of the world, with some of the highest mountains. Bounded by the Kun Lun Mountains in the north, and the Karakoram peaks to the south, including Broad Peak, K2 and Gasherbrum, on the southeast it is adjacent to the highest battlefield in the world on the Siachen Glacier region. [...] Also for an idea of the extent of the Trans-Karakoram Tract or the Cis-Kuen Lun Tract, a view the map (C) from the Joe Schwartzberg's Historical Atlas of South Asia at DSAL in Chicagowith the caption, "The boundary of Kashmir with China as portrayed and proposed by Britain prior to 1947" would show that the geographical and territorial extent of the Trans-Karakoram Tract or the Cis-Kuen Lun Tract is more or less the territory enclosed between the northern most line and the innermost lines!
