Yangtso to Gyao. 12 miles.

N.B. From Yangtso to Yala Shambo is approx 45° - 50°.
From Cyachungha to Chilungha is approx 150°.

From the lake the path leads up to a small pass at m 1/2, to the South, called the Cyachungha. From here descent is very easy to grassy valley bed and to the Sikung River, crossed at m 4. The Cyachungha is probably 16500' or perhaps more, but is very easy. Ascent up valley opposite is again easy to m 6 1/2 where drogpa are passed. Here the path leaves the main valley and turns E fairly steeply but easily to the Chilung La at m 8. Height approx 16500 or a bit more. Path keeps to South hillside over pass and descends gently over a ridge at 8 1/2, then descends more steeply but easily into a grassy valley bed, which is followed down, past some drogpa, to the first houses, and a monastery, at Gyao. This is where the Nyam Sang Chu comes in.
