The surface of the glacier opposite to my tent was much covered with debris, and many large boulders were imbedded in the ice, which was very much fissured, rising into sharp pinnacles. As the day advanced, it was traversed by numerous rills of water, and the sound of falling stones was heard in every direction.
I had hitherto been extremely fortunate in weather, considering the season; but just at sunset, a few light clouds having first appeared in the south horizon, the sky became suddenly overcast, and light snow began to fall. Very little fell during the night, but at daybreak on the 22nd of June, just as I was preparing to start, it began to snow rather heavily. I had unfortunately no choice but to proceed. The place in which I was encamped was not at all adapted for a resting-place during a heavy fall of snow; and arrangements had already been made for the relief of the baggage porters who had come with me, by a party of Zanskaries at the top of the pass on this day.
The first part of the ascent lay up the moraine parallel to the glacier, and was extremely steep for nearly 1000 feet of perpendicular elevation, up to the top of the very abrupt ravine in which I had been encamped. Beyond this, the valley widened considerably; and as its slope was now very gentle, the glacier was quite smooth, and the path lay over its surface, which was covered by a considerable layer (five or six inches) of last winter's snow, as well as by a sprinkling of that which had fallen during the night. The ice was a good deal fissured, but in general the fissures were not more than a few inches in width; a few only were as much as two feet. The road continued for two or three miles over the surface of the glacier, which gradually widened out as I advanced. Its upper part was expanded into an icy plain of great width, bounded by a semicircular arch of precipitous rocks, except where three ravines descended into it, down which three narrow glaciers flowed to contribute a supply of ice to the vast mass in the bay. On the smooth ice below, central moraines were very visible, and could be distinctly traced to the rocks by which the three smaller glaciers were separated. A great part of these central moraines were covered with snow; but now and then an immense detached boulder of gneiss was seen, supported by a column of clear blue ice, veined with horizontal white bands, by which it was raised high above the surface of the glacier, and the snow which covered it.
