Hrs 16. On Aug 15 left Tsona for Dongkar, re-entered into the Nyam Jang Chu valley by the Gorpo La, (17,750). We both fell in love with Dongkar. It lies within the dry zone & we basked in the rays of a Tibetan sun & saw beauty in the bareness of the surrounding mountains. Here we saw

Descending the Nyam Jang Chu, we crossed the Cho La into the Taree Rong Chu Valley, where the vegetation showed the rainfall to be considerable, though we were still north of the main range. Here we found

Our new pass, the Cho La, took us across the Himalayan Range, & we overlooked the beautiful valley we had gazed into from the Me La the previous year. On 22 Aug we crossed the Me La & took up our quarters in our old camp at Shengbe.

Sangla - we had a magnificent view of
the Nyam Dzong Chu Valley stretching away
to the North, whilst immediately below us to
the west Dongkar with Dzong could be
easily discerned.
We were standing on the Tibetan plateau
country & it was at once realized that the
main Himalayan range was to the south of us.
