[Sidenote: SABU VALLEY. _October, 1847._]
I left Le on the morning of the 11th of October. The road to the Sabu valley enters the granite range close to the town, ascending a narrow stony valley in an easterly direction, and crossing by a short steep ascent a depression in the ridge, to descend into a narrow ravine which has a south-east course into the Sabu valley, up which the road led. The hills were very stony and bare, or covered with the large _Echinops_ of the Indus valley, of which the heads of fruit were falling to pieces. I encamped for the night in the valley of Sabu, which is very like that of Le, with pretty extensive cultivation, but few trees.
[Sidenote: LAZGUNG PASS. _October, 1847._]
Next day I crossed the pass. The ascent was very long and fatiguing, and, from the lateness of the season, very uninteresting. A cold bleak wind blew from the north in strong gusts, and the sky was overcast with light clouds. The valley contracted into a rocky ravine before the road left it to ascend rapidly the steep mountain-sides, which were covered with masses of boulders, heaped together in great confusion. The upper part of the ascent, which was very steep, was covered with snow, which lay on the loose stones of the crest to the depth of about a foot. It was late in the evening before I reached the top of the pass, the distance being much greater than I had been led to anticipate. The elevation of the summit, by the observations of Captain Strachey, is about 18,300 feet.
On the north face of the pass snow lay thickly for two miles or rather more, and more scantily for a mile further. As evening had begun to close before I reached the summit, I hurried my descent as much as possible. Fortunately, a great part of my baggage porters were in advance, but it had been for some time quite dark before I reached a spot sufficiently free of snow to be suitable for an encampment. The night was intensely cold, the sky being clear; and next morning, at half-past six o'clock, the thermometer stood at 15°. At the same time I found that water boiled at 184°, indicating an elevation of upwards of 15,500 feet.
In the morning I made a short march to the village of Digar, which I ought to have reached the day before, had not the darkness prevented me. The distance was not more than four miles, and the descent about 2500 feet, Digar being rather more than 13,000 feet above the level of the sea. The general direction of the valley in which I was encamped was north-east, and it was surrounded on all sides by extremely rugged mountains, now much covered with snow, down to about 14,000 feet. Throughout the descent, vast piles of boulders, heaped one on another, and forming steep banks, evidently moraines, occupied the flanks of the valley. The village of Digar, though small, and possessing only two small trees, had a considerable extent of cultivation, and seemed prosperous. It was situated on the left side of the valley, or rather on the slope of the mountains on that side opposite a lateral ravine, from which a stream of boulders had at one time descended. The centre of the valley was much lower, being excavated out of the alluvium which had once filled the whole.
