| LAKES AND PASSES SOUTH OF BOGTSANG -TSANGPO. 155 very weathered and rotten. A large sheepfold of stone was erected near the spring. The latitudinal valley slopes very slowly to the east, and the transverse valleys are directed to the N. E. and N. 60° E. At the openings of several small valleys, there are ice-sheets from the springs. Caiiip XCI was erected near the mouth of a larger transverse valley containing springs with open water, ice and good grass. Here the living rock was greenish grey sandstone. The name of the place, including the region to the east, was Kunglung. Continuing south from Cainft XCI, a road crosses the great range in a pass, which was said to be too high for our tired animals, so we were advised to continue a bit eastwards and S. E. to Sarya-la, which was easier and which leads to a district called Nadsum. The frontier between Tang yung and Naktsang was said to be at Seriya, about halfway on the day's march. To the E. N. E., a lake was in sight. Its name was given as Kung-tso. Around it were said to be some tents of the Naktsang nomads. To the N. E. from our camp, there also seemed to be a lake, at least extensive ice-fields and some open water were seen in that direction along the foot of the northern hills. One gets the impression that the latitudinal valley, which here in the east becomes as broad as a plain, is a geographical analogy to the valley of the Bogtsang-tsangpo, thus sloping to the east, and having a principal, now dry, watercourse falling into the Kung-tso. This conclusion also seemed confirmed by the N. E. course of the southern tributaries. But our Tibetan guides asserted that this was not the case. There was no principal watercourse and no lake that could be compared with the Dagtse- tso as a general recipient of the whole latitudinal valley. The larger bed we had seen at Camp XC, does not reach the Kung-tso. There were general small depressions on the plain, independent of each other, and containing some water in the summer. Now, in how far this is correct is difficult to say, as the Tibetan views of physical geography are not quite reliable. From Camp XCI, Pan. i 03A and i o3B, Tab. 18, was sketched, so far as a distant view was allowed, for just behind us, we had the rocks and slopes of the Dungying Range hiding everything to the south and S. W. To the N. 45° and 4o° W. we have the ridges and peaks of Sang -chung. To the N. i 6° W. is Porten!, a fairly high mountain. To the N. i 2° W. is the pass Kanda-la, and a little to the left or west of it the Shamda-la, both with roads to the valley of the Bogtsangtsangpo. In the same direction and at a considerable distance, there is a high mountain-mass with snow. To the N. 3° E. is a pass valley called Yakiung, pronounced Yaglung, with an easy road to Bogtsang-tsangpo. To the N. 40° E., is a region, Kongo or Kon-go. Just to the right of the latter, or N. 41 ° E. is a ridge Keva, high and of a red colour, at the northern foot of which the latitudinal valley of the Bogtsang-tsangpo was said to be situated, without any parallel valleys between. | |
