SUMMARY:
After a late start from Tsuna, the party visited the Dzongpon to fix prices, then traveled via the Drong toward Lablung, ascended to the Nyongchung La, and descended into the Thang Chu valley where fuel and grazing were noted. Few flowers were seen, but a delphinium and a Corydalis were recorded; Himalayan blackbirds were numerous at Thang and gazelle were observed in the valley.

= 14869 x 1.05 = 15612'. Ht of Thang = B.P. 186.4°, Temp. 52°.
Mean with Pass 56° = 13903' x 1.015 = 14120'.

Leave camp at Tsuna village & proceed to the Drong, reached at m 1. Thence across the plain to the north, towards the village of LABLUNG. At m 2 — ½ m short of the village turn right handed up a valley to the NYONGCHUNG LA at m 4. Ascent easy over open hillside. Bearing from La to Tsuna = 235° Mag. Rather steeper descent at 60° Mag to the Thang Chu valley. Follow up this valley across by a bridge at m 6. Good C.G. fuel available but limited: grazing, food.

A very late start, not moving off till nearly 10 am. Then a call on the Dzongpon till 11 while prices were fixed. Few flowers seen. A nice delphinium on the way up the valley to the pass, & a beautiful little Corydalis at the very top. Himalayan blackbird at Thang fairly numerous. Saw gazelle in the valley.
