CHAPTER XXII.
SURROUNDINGS OF THE MANASAROVAR.
The pass Tamlung-la or Tag-la is important as being the watershed between the great Tsangpo and the Satlej. Its height is 5,279 m. (17.315 feet). It is very easy, being situated in a flat moraine consisting of granite in several different varieties. The intermediate spaces between the blocks and gravel are often filled with grey and yellowish sand which also sometimes covers the ground with a thin layer. The configuration of the ground does not allow the formation of dunes. On both sides of the pass are several pools which may he regarded as the remains of old moraine lakes.
Tamlung-la is only a threshold in a longitudinal valley. The view is comparatively open. To the south are those gigantic mountains belonging to the Ladak range between Gurla-mandata and kubi-gangri. To the S.S.W. the two ridges, between which the Ganglung glacier is situated, are only partly visible. This glacier is the source of the Ganglung-chu, which lower down is called Tage-tsangpo, the uppermost part of the Satlej, even if it periodically may be cut off from the river below Dölchu-gompa. The brook beginning from Tag-la is called Tage-tsangpo, a name that is used for the joint river the whole way down to the lake. The narrow valley of this river, which is visible to the N. 77° W. is also called Tag. The mountains to the N.W. being a part of the ridge separating the Tag valley from Gunchu-tso, are, at least partly, called Chumik-ri. S. 38° W. is a mountain called Hlalung, and to the west is an isolated mount called Dogri, to the left of which one gets a glimpse of Gurla.
The longitudinal valley is broader to the west of the pass than to the east, where several ramifications may easily give the impression of a transverse ridge of the shape as on Ryder's map. At a place called Chian-karpo the road from the pass first comes in contact with the Ganglung-chu, just where it pierces an old moraine in a wild and noisy cascade.
