"When we got a little light in the morning we found we were a little north of the two patches of moraine on Terror. Though we did not know it, we were on the point where the pressure runs up against Terror, and we could dimly see that we were right up against something. We started to try and clear it, but soon had an enormous ridge, blotting out the moraine and half Terror, rising like a great hill on our right. Bill said the only thing was to go right on and hope it would lower; all the time, however, there was a bad feeling that we might be putting any number of ridges between us and the mountain. After a while we tried to cross this one, but had to turn back for crevasses, both Bill and I putting a leg down. We went on for about twenty minutes and found a lower place, and turned to rise up it diagonally, and reached the top. Just over the top Birdie went right down a crevasse, which was about wide enough to take him. He was out of sight and out of reach from the surface, hanging in his harness. Bill went for his harness, I went for the bow of the sledge: Bill told me to get the Alpine rope and Birdie directed from below what we could do. We could not possibly haul him up as he was, for the sides of the crevasse were soft and he could not help himself."[1]
"My helmet was so frozen up," wrote Bowers, "that my head was encased in a solid block of ice, and I could not look down without inclining my whole body. As a result Bill stumbled one foot into a crevasse and I landed in it with both mine [even as I shouted a warning[2]], the bridge gave way and down I went. Fortunately our sledge harness is made with a view to resisting this sort of thing, and there I hung with the bottomless pit below and the ice-crusted sides alongside, so narrow that to step over it would have been quite easy had I been able to see it. Bill said, 'What do you want?' I asked for an Alpine rope with a bowline for my foot: and taking up first the bowline and then my harness they got me out."[3] Meanwhile on the surface I lay over the crevasse and gave Birdie the bowline: he put it on his foot: then he raised his foot,
