342 THE SECOND CROSSING OF THE TRANSHIMALAYA.
and to the W. S. W. again the Tsangpo valley, in this direction still more narrow
than to the east. Remembering that Pusum has an altitude of 4,062 m. whilst
Chaga, higher up the river, has only 4,03 2 m., a look of the Pan. 154A will explain
this seeming discrepancy. It shows that Pusum is situated on a rather high terrace
on the left bank of the river.
Pan. 148, Tab. 26, is drawn from a point less than 1 km. N. W. from Chaga.
Here we behold the valley of the Tsangpo to the south, to the S. 67° W. Mount
Dombi-tang, to the S. 81° W. the more distant Karong; between the latter two the Damchu - kamba or Tsangpo comes out from the W. S. W. To the W. N. W. is
the tributary valley of the Dok-chu with our road to the second crossing of the
Transhimalaya and with the Mount Dambo-richen in the background.
Pan. 153, Tab. 2 8, is a little view from Camp CXXXV, Chaga, showing to
the N. W. the valley of Yangyö and in the background, Mount Gesu. Pan. i 5 5A
and B, Tab. 28, represents, to the south, the monastery of Pinsoling, and to the S. 2 8° W. the peak Ngombi-chong To the W. N. W. is again the Dok-chu valley
and to the N. W. the Yangyö valley; a part of Mount Gesu stands between the
two. Pan. 155A should be compared with the fourth photograph opposite p. 304
of Vol. II for getting an idea in how far it is correctly drawn.
Finally Pan. 159, Tab. 29, is taken from the confluence of the Tsangpo and
the Dok-chu. To the S. 49° W. the Tsangpo valley is visible. In the foreground
to the left is the surface of the river. The Dok-chu itself is not visible, as I was
standing on the low gravelly cape between the two rivers.
The second crossing of the Transhimalaya was regarded as beginning from
the confluence of the Tsangpo and the Dok-chu (Vol. III, p. 266 et seq.). The
absolute altitude of this point was considered to be 4,013 m. On April 5M, we
marched 12.7 km. W. N. W. to Camp CXXXVI, Tangna, at an altitude of 4,038 m.,
being a rise in the valley of the Dok-chu of 25 m., or as I : 508, which is a little
steeper than the fall we calculated from the same confluence to Chang-tang near
Shigatse, where we found I :571. From Tangna Pan. 158, Tab. 29, was drawn,
showing to the S. 65° E., the valley of the Dok-chu going down to the confluence.
On April 7M, our march goes 14.9 km. westwards, rising 32 m., or to 4,070 m.
which is the altitude of Camp CXXXVII at Lingö, a very short distance below
the confluence of the Mü-chu with the Dok-chu. The rate of ascent is here i :466.
The sketch I drew from this place, Pan. i6 I A and B, Tab. 2 9, will give the reader
a very good idea of the appearance of the mountains around the confluence of the
two rivers. To the N. 74° E. we have the valley of the Dok-chu going down to
the confluence with the Tsangpo. S. 20° W. is the little valley of Doglo, S. W. is
Mount Dent, to the west is the Dok-chu valley and round the corner in the
foreground, W. N. W., the road turns up the valley of Mü-chu.
