Dongkha La
The Dongkha la or Donkia Pass() (el. ) 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  is long and  wide, and is the source of the Teesta River. Gurudongmar Lake, some  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 7September 1849. References
