Some twenty minutes later, as we sat on the snow gazing most intently at all that lay about us, Bullock and I were surprised by a shout. A moment later Major Morshead rejoined us, to the great rejoicing of all three. It was about 1.15 p.m. when the first two of us had reached Lhakpa La; the clouds, which had been earlier only a thin veil, rent occasionally to give us clear glimpses, had thickened perceptibly during the last hour, so that we had now no hope of a clear view. In a sense, despite our early start from a high camp, we were too late. Little was to be seen above our level. The slopes of Everest away on our left were visible only where they impinged upon the glacier. But we were not actually in cloud on the col. The South-facing rocks of Changtse presented their profile, steep and jagged, an imposing spectacle so far up as we could see; between them and Everest we looked down on a broad bay, the smooth surface of which was only occasionally broken by large crevasses. The descent to it from where we were could also be seen well enough, and we judged it perfectly simple and not much more than 800 feet.[12] The East ridge of Changtse had no existence for us; we looked across at what presumably were the splayed-out slopes supporting it. Below them was a narrow glacier (it grew when we crossed it to broader dimensions), shaping its course somewhat to the West of North, joined after losing its white snow-covering by another and cleaner glacier coming steeply down from the left, then apparently bending with this confluent to the right, and finally lost to view. We could see no more; the mountain sides, which must hem it in on the North, remained completely hidden, and for all we had seen the exit of this glacier was still a mystery. [12] It turned out to be a full 1,200 feet.
