Dongkha La Pass
People's Republic of China
The Dongkha la or Donkia Pass (el. 18, 156.2 ft or 5, 534.0 m) is a high mountain pass in the Himalaya connecting Sikkim in India with Tibet. Located in North Sikkim, the pass offers a view of the Tibetan Plateau. The nearby Tso Lhamo Lake 6.5 km (4.0 mi) is long and 2.5 km (1.6 mi) wide, and is the source of the Teesta River. Gurudongmar Lake, some 5 kilometres (3.1 mi) to west-northwest, also feeds the Teesta. The first observer to record the pass in western literature was botanist Joseph Dalton Hooker, who crossed the pass on 7 September 1849.
