The lacustrine clay formation, though not continuous throughout the whole of this day's march, may be traced in patches, with so little interval that its former continuity cannot be doubted. The spots in which I observed its presence in the narrow ravine were all close to the river, the low level of the road not permitting an extended view of the higher slopes of the mountains. Further up, however, patches were in my subsequent April journey seen at considerable elevations, but in December the slopes were covered with snow to within a thousand feet of the river. In several places the clay formed cliffs, which rose perpendicularly from the Indus, and could be seen to be covered with modern alluvium deposited during floods, just as the ancient rocks are in other places. The clay appeared everywhere extremely fine, without any intermixture of sand or micaceous grains. I saw no appearance of fossils, which I think never occur in the very fine cream-coloured clays, but seem always to accompany more sandy, or at least gritty varieties, as if the influx of a small stream, and probably the proximity of land, were requisite to the existence of testaceous mollusks; while the central part of the lake, in which the very finest clays were deposited, was quite devoid of them.
Parkuta is a very large village, three or four hundred feet above the river, occupying both slopes of a deep ravine cut in the thick mass of alluvium by a large stream from the south. The alluvium is scarped towards the Indus, and a low granitic hill, the cause of its accumulation to such a height, just rises above the general surface of the platform. This is covered with a mass of buildings, formerly the residence of the Rajah of Parkuta, a branch of the same family who ruled at Iskardo, and dependent on them while that state remained independent; he has, however, been removed by the Sikhs, and his house is at present untenanted. The village is large, with extensive cultivation, and many fine fruit-trees. Vines are plentiful, climbing over the poplars.
On the 5th of December my day's journey carried me to Tolti, a distance of twelve miles. The valley continued narrow, and the mountains rose precipitously on both sides. On the early part of the march there were many villages, and much cultivation on the left bank. The village of Urdi, three or four miles from Parkuta, seemed very populous, and extended for a great distance along the river. It was remarkable for an aqueduct supported on pillars of stone, which crossed a ravine immediately above the village. At this spot the cultivation terminated abruptly, and the alluvial platform was for more than a mile, during which space it gradually narrowed by the encroachments of the cliffs, covered with an accumulation of very large granitic boulders, which seemed to have fallen on it from the mountains behind.
