| THE BONGBA-VEKE-GANGRI RANGE. 397 the altitude is 4,756 m.; in the valley below, 4,692 m. Here we have a new view of the Tarok-tso, and to the north or N. N. E. the neck of land between the two lakes. To the east and S. E. is the range to the right of the Buutsang valley. To the S. 55° E. is Tengi - nig"uk, belonging to the latter range. Malung-gangri is still visible. In the foreground, to the S. E. is Lunkar-gomma itself. To the N. 27° E. there is one or perhaps two islands in the Tarok-tso near its northern shore. On 7une loth, we had an interesting march up the Lunkar valley W. S. W. and S. W. for 9.7 km. to Lunkar-la, 5,570 m. high. The rise from Camp CCCCXXI V was, therefore, no less than 783 m., and the rate 1 :12.4. On the other side we had 3.4 km. S. W. and W. S. W. to Camp CCCCXXV, Goang--shung, 5,349 m. high, a fall of 22 I m. and a rate of 1: 15.4. Here the northern slope is thus steeper than the southern. From Lunkar-la Pan. 515A and B, Tab. 97, was sketched. Nearly the whole of Tarok-tso, except its eastern part, was to be seen, and its islands in its northern part. A part of the salt lake of Table - tsaka could also be seen and the neck of land with its hills. To the N. 49° E. is Shakangsham, beautifully rising above everything else. From here one gets the impression that the Shakangsham belongs to a range. The snowy Mount Amlung to the N. 82° E., is difficult to place. Charko-ri, S. 79° E., is only a few kilometers distant. The mountains called Mela-gangri on Pan. 515B, Tab. 97, visible to the S. 49° W. and S. 88° W., are certainly parts of the Surla Range and the Bongba yeke-gangri. The name Melagangri was given us by our guides on the Lungkar-la. On 7une I I th, we covered 14.5 km. S. W. to Camp CCCCXXVI, Gyänortsangpo, being at an altitude of 5,187 m. or 16 2 m. below the previous camp, the rate of fall thus being I : 89. Pan. 516, Tab. 97, taken from the last camp, shows a large part of the mighty Bongba - yeke - gangri Range with its covering of eternal snow. To the W. S. W. the Poru - tso is situated, though still hidden by the low hills in the foreground. To the S. 53° E. is Mount Kaj5ta, as seen from the same camp, Pan. 517, Tab. 97. Camp CCCCXXVII, Tokya, was situated 12.7 km. S. W. of the preceding camp. The first 1 o km. took us to the Chuka-la, 5,320 m. high, a rise of 133 m. at a rate of I :75. From the pass to the camp we had 2.7 km. and a descent of only 13 m., as the latter had an altitude of 5,307 m.; the rate is, therefore, 1:208. Pan. 518, Tab. 97, shows, from S. 52° W. to N. 58° W., a mighty range, the one we have mentioned above. We have here to deal with one very considerable and nearly meridional range, the northern section of which is situated east of Nganglaring-tso and Shovo-tso, whilst its middle part is west of Poru - tso, and its southern section to the east of the Pedang Range. On my route this range, Surla, is crossed in only one pass, the Surla-kemi-la. The orographical importance of the range Bongbayeke-gangri is, on the other hand, not quite clear. It should certainly not be | | | | | | | | |
