different source branches of the river are fed. Its bed is completely filled with ice
from side to side, so far as the eye reaches, and the narrow valley is bounded by
very steep rocks and slopes. In its background, snow-mountains are visible, not
very high.

The right tributary which we follow, has ice only here and there in its upper
reaches. The valley is regular and hardly 1 km. broad the whole way. There is
not much gravel and a good deal of grass, partly the common variety, partly the
fine, low, dense, alpine grass resembling soft carpets and which is especially esteemed
by the yaks. The ground is, therefore, very comfortable, and the rise, moderate.
Dung of wild yak is abundant, proving that the animals visit these high valleys in
summer. The kyang seems to be a more rare guest. There were no signs of other
animals; only rabbits' holes.

After a march of 10 km. it became obvious that it was impossible to proceed
farther in this direction. The valley came from a ring of snow-covered flat moun-
tains where three short glaciers were seen; the one from the pass seemed to be
fed from two fields of névé. The view to the S. 30° E. is found on Pan. 382,
Tab. 67. From the same place, the point where we turned back, the sketches 381
and 383, Tab. 67, are drawn. We camped in the mouth of a tributary valley from
the east. This valley was also blocked in its upper regions by impracticable moun-
tains which appeared to be the northern ramifications from the glacier group just
mentioned. A very strong wind was blowing most of the day, though in these closed
valleys, it is difficult to tell from which direction it comes.

The height at Camp CCXCIV was 5,300 m. On January 2nd, we had 13.5 km.
down to Camp CCXCV at 5,088 m., or 212 m. lower, thus giving a fall of 1:64. The
minimum temperature was —25.2° and the sky was clear. Having built a cairn adorned
with an old yak's skull, we again marched down the valley. At the point where it joins
the Kara-kash, were two small sheepfolds about 3 m. in diameter, and probably rather
old, for it is not likely that shepherds visit these regions nowadays. Camp CCXCIII
was passed, and we continued along the right brim of the Kara-kash ice. Steep
screes of sharp-edged gravel fall down to it. Here and there are small patches with
soft ground and some grass. There is a path, though we could not tell whether it
had been trodden by men or wild animals. The valley becomes broader, with gravel
and sand to the right of the ice. The living rock is dark grey quartzitic sandstone.
Finally, the ice-sheet is divided into branches and there is no running water. The
valley turns more and more to the right or N. E. and E. N. E. In its background
there are moderate mountains, without snow. The erosion bed with its ice keeps
to the left side of the valley. Camp CCXCV was pitched on soft, sandy ground
at a narrow place of the Kara-kash valley, where grass, ice and yak dung were
abundant. Pan. 384, Tab. 67, is a sketch of the camp with its surroundings.
