In the upper part of the district of Chorbat, the villages are few and very insignificant, but lower down several are of great extent. Chulungka, the highest village, consists of three or four houses, on a small platform about fifty feet above the river. This village stood formerly on the low ground close to the Shayuk, but the cultivable soil at the lower level was entirely swept away by the flood of 1842, so that the inhabitants were obliged to change the position of their houses. The first considerable village is Turtuk, on the south side of the river. Pranu, on the north side, is remarkable for the great extent of its cultivation, and for several isolated rocks, behind which the alluvium has accumulated to a thickness of at least six or seven hundred feet.
All the villages are surrounded by fine orchards of apricot-trees. Walnut and mulberry trees are also common; and at Turtuk I saw a few vines; these latter are, however, by no means generally cultivated in the district. Willows are less frequent than in Nubra, but there are plenty of poplars. The black poplar is the common species, but a white downy-leaved species (P. alba), which is cultivated also in Kunawar, and which seems to be indigenous in some of the Himalayan valleys south of Kashmir, occurs for the first time at Turtuk. The fields are everywhere terraced, and water seems to be very abundant.
ROCKS OF CHORBAT.
October, 1847.
A very remarkable outburst of granite commences at the junction of the Boghdan ravine with the Shayuk, and continues as far as Siksa, altering the secondary rocks so that they can scarcely be recognized. The granite is frequently in great mass, and usually occupies the lowest part of the valley, sending out gigantic veins or branches into the overlying slates, which are often transformed into a coarse serpentine. The hard conglomerate which is associated with the slate, seems the same as occurs in Lower Nubra, so that probably the slates are also a continuation of the same series, and the whole may even be connected with the conglomerates and slates of the Giah valley and of the Indus below Le, the strike of which to the N.W. or N.N.W. would carry them nearly in the direction of Chorbat. Here the intrusion of the granite renders both dip and strike obscure, the beds being frequently quite vertical.
PLAIN OF KHAPALU.
October, 1847.
From Siksa, close to which there is a small fort or castle on an isolated rock, a road leads across the Hanu pass into the valley of the Indus. By this route Mr. Vigne proceeded when he abandoned his intention of penetrating by the Shayuk to Nubra, and it has since been crossed by several travellers at different times. It is, indeed, a route very commonly adopted in travelling from Iskardo to Le, as the lower part of the Shayuk is more open and practicable than the Indus below the junction of the river of Dras.
Below Siksa, the valley of the Shayuk continues narrow for eight or ten miles. It then begins again to expand, and its width continues to increase as far as Khapalu, which is situated near the centre of a wide plain similar to that of Nubra, and, like that, coincident with the junction of a large river from the north. It is certainly worthy of note, that it is always at the point of junction of large tributaries that the valley of the Shayuk is widest, and that the evidences of the former existence of lakes are most evident, while in the intermediate parts of its course the valley is narrow and rugged, and shows no certain indications of having been at any period lacustrine.
MACHULU RIVER.
November, 1847.
The great axis of the plain of Khapalu is from south-east to north-west, in the direction of the river Machulu, which runs through a very open and wide gravelly plain, apparently for a considerable distance. This stream, which is probably at least as large as the Nubra river, has its source in heavily-snowed mountains to the north. The general surface of the plain is gravelly, and its appearance on the whole is so similar to that of Nubra that no detailed description is necessary. The river divides in the open gravelly plain into numerous branches, which separate to a considerable distance from one another, and ramify very irregularly. There is not much alluvial accumulation in this plain, except in the immediate vicinity of Khapalu, where a very curious isolated rock of black slate rises abruptly in the middle of the plain, its base being washed by one branch of the Shayuk, now (after its junction with the Machulu) too deep to be forded. Behind this rock there is an accumulation of alluvium, forming a steep ridge six or seven hundred feet in height; which it is necessary to cross in travelling from Surmu to Khapalu, as the abruptness with which the clay-slate rock rises out of the water, completely prevents a passage along the margin of the river.
On the 2nd of November I forded the Shayuk a little below the village of Abadan, where it runs in two branches, each about a hundred yards wide, and with an average depth of about two feet. A little further down it is joined by the Machulu, and it does not appear to be anywhere fordable in its further course, even in winter, so that probably the influx of water brought by that stream is very considerable. I did not, however, see the junction, which is situated on the north side of the plain, quite out of the direct road towards the town of Khapalu.
