It may be regarded as pretty certain that the river, which in the summer may be
rather strong, judging from the fluviatile terraces, loses a good deal of its volume
on its way from Sha-kangsham down to Lakor-tso.

Having crossed the river, we turn S. E. along the base of the red hills, where
the living rock is grey, dense limestone, the same kind as I had found N. E. of Sha-
kangsham in 1901. A little, steep valley leads us up to the pass of 4,972 m., in
the hills of soft material. From here a range comes into sight, which starts from
Sha-kangsham and seems to run westwards and which we would have to cross
farther south. Between that range and the one of our present pass, there was a
plain. To the S. W. two tents were pitched. It may be that we could have avoided
this pass by following the Kangsham-tsangpo upwards some kilometers, for now we
got the impression that the river crossed the N. E. part of the plain. We descend
amongst hills sometimes up and down, and pitch our Camp CCCLX at the southern
side of a little hill. From the pass, a valley goes down E. S. E. and may perhaps
join the river.

From this camp, Pan. 440A and B, Tab. 81, is sketched. It shows the range
we crossed, and to the east, the prolongation of the plain which probably is traversed
by the Kangsham-tsangpo. To the S. 73° E., is again the highest peak of Sha-
kangsham, and around it and to the right of it, a labyrinth of ranges and ridges,
being more or less in connection with the great snowy group. The plain east and
south of our camp, belongs to the latitudinal valley situated north of Sha-kangsham.
Its eastern part is, as is shown to the N. 88° E., on Pan. 440A, quite closed by
mountains.

The two tents S. W. of the pass, were inhabited by a man, three women and
three children, possessing 200 sheep. The latter were weak and meager, as they
had, one month ago, returned from a journey south, to Kirong. The nomads asserted
that the region around Camp CCCLX, was called Kombak. From this place, roads
were radiating in different directions. If we went to the S. E. and E. S. E., passing
a dark projecting hill visible from our camp, we would, after having crossed a high
pass, finally reach Chokchu. Now, as there is a province of that name between
Dangra-yum-tso and Teri-nam-tso, which is indeed E. S. E. of Kombak, the infor-
mation was obviously correct. We were also told that it was a three days' journey
W. S. W. to the tent of a chief, and that a high pass had to be crossed. If we continued
S. S. E., we would reach, in one day, a pass called Chaklam-la, the entrance of
which is visible on Pan. 440. Taking the last-mentioned road, we would leave to
the west both the chief's tent and the lake, Yum-tso. As we heard different nomads
mentioning this lake, it, no doubt, exists, though it is probably somewhere west of
our road. The name Yum-tso-la, therefore, seems doubtful, as its single raison d'être
