THE YURUNG-KASH PROBLEM.

399

a

Stein's journey of r 900 had left several problems unsolved as to the uppermost course of the Yurung-kash and of its main feeders.'

On his second great expedition he solved the Yurung-kash problem definitely. On his previous excursions in the Karangu-tagh Mountains he had felt convinced that the Yurung-kash head-waters were quite inaccessible through the narrow and deep gorges cut down by the river on its course westwards. He therefore decided to attack this wholly unexplored region from the east. His plan was then to make his way to the uppermost Kara-kash Valley along the unsurveyed southern slopes of that portion of the main Kwen-lun Range which feeds the Yurung-kash with its chief glacier sources.

He started from Polur, August i 8th 1908, reached Zailik and travelled down to the deep-cut canon of Upper Yurung-kash. With plane-table, theodolite and photographic panoramas he mapped »the greater portion of the inexpressibly grand and wild mountain system containing the unexplored eastern head-waters of the Yurungkash». — »On the south for a distance of over sixty miles, we could see them flanked by a magnificent range of snowy peaks, rising to over 2 3,000 feet, and all clad with glaciers more extensive than any I had so far seen in the Kun-lun.»

From Zailik he travelled up partly along the river, partly on the mountain spur at its sides to the very source region, which he mapped in minute detail. From there he continued westwards, travelled along the northern shore of Lake Lighten and mapped the upper course of the Kara-kash and its glacier sources.2

Stein has definitely cleared up this complicated region which had been only touched by a few other travellers.
