Our start at an early hour on the 20th was propitious enough. It was the same moonlit glacier of our expedition a month before as we made good our approach to its surface. But the conditions were altered. For the first time since we had come to these mountains we experienced the wonderful delight of treading snow that is both crisp and solid. We walked briskly over it, directly towards Mount Everest, with all the hope such a performance might inspire. The night was exceedingly cold and there was no untoward delay. In less than an hour we were at the foot of the icefall. We were determined on this occasion not to avoid it by the rocks of the left bank, but to find a quicker way through the tumbled ice. At first all went well. A smooth-floored corridor took us helpfully upwards. And then, in the dim light, we were among the crevasses. To be seriously held up here might well be fatal to our object, and in the most exciting kind of mountaineering adventures we had the stimulus of this thought. We plunged into the maze and struggled for a little time, crossing frail bridges over fantastic depths and making steps up steep little walls, until it seemed we were in serious trouble. One leap proposed by the leader proved too much for some of the laden coolies and a good deal of pushing and pulling was required to bring them over the formidable gap. We had begun to waste time. Halted on a sharp little crest between two monstrous chasms Morshead and I discussed the situation, and thereafter gravely proceeded to reconnoitre the ground to our left. In ten minutes we came to another corridor like the first, which brought us out above the icefall. We were well satisfied with our progress as we halted at sunrise, and it was a pleasant change to get our feet out of the snow and knock a little warmth into chilled toes. But our confidence had ebbed. Even as we entered the icefall our feet had occasionally broken the crust; as we came out of it we were stamping a trail.
