I o8 THROUGH MERIDIONAL VALLEYS.
From the little pass south of the fresh DungIsa-tso Pan. 73, Tab. I 1, was drawn, showing the Nb emba-dungtsa Mountains to the S. E. and small parts of both lakes. Pan. 75A and 75B, Tab. 12, gives a clear idea of the general habitus both of Cliipcha-karmo and of Ngemba-dungtsa as seen from Camp LX V We see that both are comparatively large, a fact that explains their having geographical names. To the S. E. the same panorama shows the little salt lake Dungtsa-Iso quite near the camp.
Though Camp LX V was at a lower altitude, or 4,914, the minimum temperature in the night went down to —32.9°, but the winter was advancing. On No-
vember 20th we marched 17.8 km. chiefly S. E., keeping at nearly the same altitude the whole way. Camp LXVI was at 4,928 m. or only 14 m. higher than Camp LX V. Between the two, there was, however, a little threshold of 4,98o m. separating two small self-contained basins from each other. Our march, to begin with, makes a little turn to the west, avoiding the ice-sheets of the spring and the salt shore-plain of
the lake. But after a while we follow the lake itself on ground of sand with some grass. At some places springs are seen around the lake. The water is open and
of a fine green colour. Tables, walls and other formations are modelled in the white
salt deposits around the lake. In the S. E. prolongation there is a fresh-water pool, probably formed by springs, and frozen hard. On the hills in the neighbourhood
were two flocks of kyangs, of 3o and 150 individuals respectively. No yaks or ante-
lopes were seen in this valley. The ground is nearly level to the eye. To our left is a little dry depression. By and by the ground slowly rises to the S. E., as may
be seen from the direction of the erosion furrows from the hills. Sometimes there is some grass or the dry, hard plants called yer-baghri in Turki , but other places are perfectly barren. Gravel is rare; the soil consists of sand.
The Ngernba-dungtsa group comes to an end. On the south it is bounded by a little transverse valley that seems to fall to the N. E. At a short distance in
that direction, three tents were said to be pitched. A meridional mountain range of moderate height to the east was called Keling-tavo-amchuk, and the whole region there about Keling, pronounced nearly like Kling. To the east was an isolated peak of conical shape, called Chea-govo-rachek. Leaving the little valley to our left, we slowly rise to the threshold of 4,98o m. from which our direction becomes E. N. E., following a dry watercourse. Here the landscape is again completely changed. At the foot of hills which seem to be ramifications from the Keling Mountains, is the
very small lake of Pulka-tso (pronounced Puka) and S. E. of it are two pools covered with solid ice. The one at the S. W. shore where Camp LXVI was pitched, had
open water at two places, obviously from springs in the bottom. A black tent had just arrived from Gertse and intended to stay here for three months. The place is called Ngemba-tokchen, and in the neighbourhood is a place with gold sand.
