There are here no inviting grassy slopes and no enticing forests. The mountain-sides are all hard rock and rugged precipices. And the summits are of ice or with edges sharp and keen direct from Nature's workshop. But the sight, though it awes us, does not depress us or deter us. We are keyed up by high anticipation when we arrive on the threshold of this secluded region, and a fierce joy seizes us as we first set eyes on these mountains. We know we have before us one of the great sights of the world--something unique and apart, something the like of which we shall never see again. And awed as we are by the mountains' unsurpassed magnificence, we do not bow down in any abject way before them. We are not impressed by our littleness in comparison. They have, indeed, shown us that the world is something greater than we knew. But they have shown us also that _we_ too are something greater than we knew. The peaks in their dazzling altitude have set an exacting standard for us. They have incited us to rise to that standard. Their call is great, but a thrill runs through us as we feel ourselves responding to the challenge, collecting ourselves together and gathering up every stiffest bit of ourselves to rise to their high standard. We feel nerved and steeled; and in high exhilaration we plunge down into the valley to join issue with the mountains. Arrived on the Oprang River we can turn either to the left or the right. If we turn to the left we get right in under a knot of stupendous peaks. Towering high and solitary above the rocky wall which bounds the valley on the south is a peak which may be K2, 28,250 feet in height, which must be somewhere in the neighbourhood. But the investigations of the Duke of the Abruzzi throw a doubt as to whether this can be K2 itself. If it is not, it must be some unfixed and unnamed peak. At any rate it is a magnificent, upstanding peak rising proud and steep-sided high and clear above its neighbours. Then beyond it, farther up the Oprang Valley, we catch glimpses of that wondrous company of Gusherbrum Peaks--four of them over 26,000 feet in height, with rich glaciers flowing from them. But if we turn to the right on descending from the Aghil Pass, and if we turn again in the direction of the Mustagh Pass, we come to an icy realm which has about it, above every other region, the impress of both extreme remoteness and loftiest seclusion. As we ascend right up the glacier--either the one coming down from the Mustagh Pass or the one to the east running parallel with the general line of the Karakoram Range--we feel not only far away from but also high above the rest of the world. And we seem to have risen to an altogether purer region. Especially if we sleep in the open, without any tent, with the mountains always before us, with the stars twinkling brightly above us, do we have this sense of having ascended to a loftier and serener world.
