[Sidenote: VALLEY OF DRAS. _April, 1848._]
On the 6th of April, I entered the Dras valley, and encamped at Ulding Thung, where there were still a few patches of snow. On the 7th, I marched to Hardas, ten miles. Here, at about 9000 feet, spring had scarcely commenced. The fruit-trees showed no signs of vitality; and though the fields had been ploughed, the grain had not yet begun to vegetate. The valley of the Dras river begins to expand at the village of Bilergu, four or five miles above Ulding. As soon as there is enough of level space, beds of conglomerate, and more rarely of fine clay, appear along the river. Round the village of Bilergu, the poplars, willows, and apricots are as numerous as in the valley of the Indus; but beyond it, the inclination of the valley is considerable, and at Hardas there were but few trees. Above Bilergu the quantity of snow increased considerably, and the contrast between the sides of the valley was very striking: at Hardas, the shady slope was quite white, while that facing the south had only a few patches of snow.
On the 8th of April, I marched to Karbu, eight miles. As I advanced, I found much more snow; but the road was in general free, except in the ravines where snow-slips had descended. On the latter part of the day, these were universal in all the ravines, and were frequently of great depth, and so soft as to be difficult to cross: on the least deviation from the beaten path, I sank to the middle at every step. These avalanches were cut off abruptly by the river, forming cliffs of snow fifteen or twenty feet high, in which the structure and development of the mass by successive slips, alternating with falls of snow, could be distinctly made out. One or two of them still crossed the river, which flowed below the bridge of ice. Three miles below Karbu, the granite, which had been the rock ever since entering Dras, was replaced by a peculiar slate, apparently magnesian, and perhaps hornblende slate, passing into or containing beds of a coarse sandstone.
At Karbu, where I was detained a day, the Thannadar not having expected me so soon, and my porters not being ready, the weather was very unsettled, and in the evening, and during the nights of the 8th and 9th of April, there was a good deal of rain, especially on the 9th. The wind during the storm was very irregular in direction. The ground was still covered to the depth of more than a foot with snow. The morning of the 10th was gloomy, but as the day advanced the clouds broke, and the afternoon was bright and beautiful, with a gentle air down the valley.
