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-
chen.* 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 1:40, 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 *Targo-
tsangpo,* 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 *Gip-
chung,* 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 *April 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 1:11.2. The *Bumnak* is a tributary to the *Targo-tsangpo.* From the pass we
have 10 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 1:28.7. 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 1:29.
Three interesting panoramas were drawn on *April 26th.* The first, 172A 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. 280 and
p. 281).
