THE SECOND CROSSING OF THE TRANSHIMALAYA.
Our road to Bumnak, Camp CXLVIII, on April 24th, is 24.6 km. in length and proceeds in a nearly north-westerly direction. On this section one has again the impression of being on the Chang-tang. The first third of the road follows the right bank of the Targo-tsangpo to the entrance of the right tributary Lung-then. On the second third the road crosses insensibly rising ground to the pass Chumar-la, 5,108 m. high and only 58 m. above Kyang-dam. From the pass we go down to Camp CXLVIII, Bumnak, with 4,945 m. On this section of 6.6 km., we fall 163 m. or as I :4o, a steep slope indicating the approach of the depression
of Dangra yum-tso.
Two panoramas taken on this road give an idea of the landscape. The first, Pan. 178, Tab. 32, is drawn at the confluence of the Lung-chen brook with Targotsangpo, and shows, to the S. 36° E., the valley of the Upper Targo-tsangpo by which we have come. To the S. 5° W. is Mount Tasang, to the S. W. Mount Gipchung, to the S. 65° W., the comparatively considerable peak Mukbo-chung, to the S. 78° W. the valley by which the Targo-tsangpo goes down, soon turning to the N. W. and approaching the lake. To the W. N. W. is a mountain called Kurtam. The view from Chumar-la is represented on Pan. 173, Tab. 31. In its midst we see again Mukbo-chung and to the right of it N. 63° W., Mount Bumnak.
On Aril 25th, our road proceeds 1.8 km. W. S. W. to the pass Ting-la, 5,105 m. high or 160 above the Bumnak camp; the rise is, therefore, considerable or I:1I.Z. The Bumnak is a tributary to the Targo-tsangpo. From the pass we have I o km. N. W. to Camp CXLIX at Kokbo where the altitude is 5,110 m. On this section the road goes up and down.
On April 26th, we accomplished the last day's march on the second crossing. The road goes 4.5 km. W. N. W. to Tarbung-la, 5,267 m. high, a rise of 157 m., and a rate of i:28.7. On the other side we had 16.2 km. N. W., descending 559 m. to Camp CL at Targo-tsangpo, being nearly the same slope as on the eastern side, or I :29.
Three interesting panoramas were drawn on April 26th. The first, 17 2 A and B, Tab. 31, is from the saddle of Tarbung-la and shows to the east a wavy sea of hills, near and distant. Amongst the mountains to the S. 29° W. the pass of Sha-la is pointed out by the guide. This information is, however, doubtful, as the pass according to other Tibetans was situated rather south of Tarbung-la. At any rate it seems no doubt to be on the continental water-parting, and, probably, on the same range as the Chesang-la, not on the same range as Sela-la and Chang-la-Pod-la, as I first believed. The most interesting view from Tarbung-la is the magnificent panorama of Targo-gangri unrolling its snow-covered and icy peaks from N. 73° W. to N. 37° W. The same view was photographed (Vol. III, between p. 28o and
p. 281).
