During the whole day I was never free from a dull headache, evidently caused by the great elevation. Rest relieved it, but the least exertion brought it back again. It continued all evening, as long as I was awake, and still remained in the morning of the 8th, when I rose soon after daybreak to prepare for the journey. A few paces took us beyond the shingly ravine in which we had been encamped, and the remainder of the ascent was throughout over loose angular fragments, the _débris_ of the cliffs on the right. Under the latter we passed, winding round the side of the semicircular bay, till we got to about its centre, when the ascent became excessively steep and toilsome. The exertion of raising the body was very fatiguing, and the last few hundred yards were only accomplished after many pauses. A few large patches of snow lay in hollows along the road; but up to the very crest of the pass there was no trace of perpetual snow, nor even any continuous snow-bed.
[Sidenote: THE PARANG PASS. _September, 1847._]
The summit of the Parang pass is a narrow ridge, covered with large blocks of stone. To the north lay a large field of snow, sloping downwards at a very gentle angle. In this direction the view was limited within two miles by steep rugged mountains, which closed in on both sides. To the right and left also, the pass was overlooked by ridges close at hand. The only direction in which a distant view was obtained was south, where the mountains beyond the Piti river were beautifully seen: from the great elevation at which we stood, their summits were everywhere in view; their elevation was surprisingly uniform, and the whole range was capped with snow. The mountains close at hand presented much the same appearance as I had seen from the rocks above our encampment the day before.
I reached the summit of the pass, which has an elevation of 18,500 feet, at a quarter before eight in the morning. At that time the temperature was 28°; and a cold southerly wind blew with considerable violence, making us seek the shelter of the blocks which lay around. A small red lichen, (_Lecanora miniata_,) on the fragments of rock, was the only vegetable production I observed. After an hour's rest, we commenced the descent over the snow-bed, proceeding towards a gap which was visible in the mountains. The snow was hard frozen, and crisp under the feet. Descending steadily without any fatigue, we were soon evidently on a snow-covered glacier. A few fissures were passed, but mostly not above a few inches wide, and none that we could not with ease step over, the widest not exceeding two feet. At a distance of about a mile and a half from the crest, the mountains, which on both sides surrounded the snow-bed in the form of a circle, had so much approached to one another, that they formed a narrow valley, down which the snowy mass continued in the form of a rugged glacier. We now left the surface of the ice, and proceeded along the stony side of the ravine, with the glacier on our left hand, and steep limestone rocks on our right. Blocks of limestone strewed our path as we descended, and numerous small fragments of the same rock covered the edge of the glacier.
