very small pass, past ruined village, joining the route from Tsona Dzong at mile 4. From Tsona Dzong the route skirts the East end of the hill and crosses a broad open plain, and runs at a bearing of approximately 325° Magnetic. At mile 4 the plain narrows, and the path ascends a valley, climbing gradually to the Nyaba La at mile 6. This pass is approximately 15,250 feet, where the route splits, one to Dongkar keeping up to the left and going due north, while the other leads down to the West end of the Nyaba Tso, a lake about 1 mile x 1/2 mile broad to the East of the Nyaba La. From Nyaba La proceed North over open hillside. At mile 8 another similar sized lake is passed, lying to the East of the path. At mile 9 the path ascends, gradually turning westward and climbing pretty steeply to the Gorpo La, which lies between two high mountains, from which several glaciers fall to the Southeast. The one on the North must be well over 20,000 feet. The La is reached at mile 11 and is 17,779 feet. The path is rocky but easy. Descent on West side also easy, down a series of small plateaus. A route leads down the main valley to the West to the Nyam Jang.
