Again and again Otmar sought a way out of the maze, taking us across perilous snow bridges and cutting steps on knife-edges of ice where one looked down the glittering slope on one side, and into the merciless green-blue depths of the crevasse on the other. But wherever he turned he was baulked. Always the path led to some vast fissure which could be neither leapt nor bridged. Once we seemed to have escaped and glissaded swiftly down. Then the slope got steeper and we walked—steeper and Otmar began cutting steps in the ice—steeper and Otmar paused and looked down the leap of the glacier. We stood silent for his verdict. "It will not go." We turned on the rope without a word, and began remounting our steps.
It was half-past four. The mist was thickening, the rain falling steadily. Below, the red roofs and green pastures of Grindelwald gleamed in the sunlight of the valley. Nearer, the slate roof of the Gleckstein on its spur of rock was still visible. Two hours before it had seemed but a step to either. Now they seemed to have receded to another hemisphere.
For the first time there flashed through the mind the thought that possibly we should not reach the hut after all. A night on the glacier, or rather on the dark ridges of the Wetterhorn! A wet night, too.
The same thought was working in Otmar's mind. No word came from him, no hint that he was concerned. But the whole bearing of the man was changed. In the long hours of the morning he had led us listlessly and silently; now he was like a hound on the trail. The tug of the rope became more insistent. He made us face difficulties that he had skirted before; took us on to snow-bridges that made the mind reel; slashed steps with his ice axe with a swift haste that spoke in every stroke of the coming night. Once I failed to take a tricky snow ridge that came to a point between two crevasses, slipped back, and found myself in the crevasse, with my feet dancing upon nothing. The rope held; Otmar hauled me out without a word, and we resumed our march.
Heinrich had been unroped earlier and sent to prospect from above for a possible way out. We followed at his call, but he led us into new mazes, down into a great cavern in the glacier, where we passed over the ruined walls and buttresses of an ice cathedral, emerging on the surface of the glacier again, only to find ourselves once more checked by impassable gulfs.
It was now half-past five. We had been three and a half hours in vainly attempting to find a way down the ice. The mist had come thick upon us. The peaks were blotted out, Grindelwald was blotted out; the hut was no longer visible. Only an hour and a half of light remained, and the whole problem was still unsolved. The possibility of a night on the ice or the rocks began to approach the sphere of certainty. My strength was giving out, and I slipped again and again in the ice steps. A kind of dull resignation had taken possession of the mind. One went forward in a stupor, responsive to the tug of the rope, but indifferent to all else.
Otmar was now really concerned. He came from a valley south of the Rhone, and was unfamiliar with this pass; but he is of a great strain of Alpine guides, is proud of his achievements—he had led in the first ascent of the Zmutt ridge of the Matterhorn that year—and to be benighted on a glacier would have been a deadly blow to his pride.
He unroped himself, and dashed away in the direction of the ridge of the Wetterhorn that plunged down on our right. We watched him skimming across crevasses, pausing here and there to slash a step in the ice for foothold, balancing himself on icy ridges and vanishing into a couloir of the mountain—first depositing his rucksack on the rocks to await his return. Five minutes passed—ten. Heinrich startled the silence with an halloo—no answer. A quarter of an hour—then, from far below, a faint cry came.
"It will go," said Heinrich, "get on." We hurried across the intervening ice, and met Otmar returning like a cat up the rocks. Down that narrow slit in the mountain we descended with headlong speed. There were drops of thirty and fifty feet, slabs of rock to cross with negligible foot and hand holds, passages of loose rock where a careless move would have sent great stones thundering on the heads of those before. Once Heinrich lowered me like a bale of goods down a smooth-faced precipice of fifty feet. Once he cried: "Quick: it is dangerous," and looking up at the crest of the Wetterhorn I saw a huge block of ice poised perilously above our downward path.
The night was now upon us. We were wet to the skin. A thunderstorm of exceptional violence added to the grimness of the setting. But we were down the ridge at last. We raced across a narrow tongue of the glacier and were safe on the spur of rocks where we knew the Gleckstein hut to be. But there was no light to guide us. We scrambled breathlessly over boulders and across torrents from the Wetterhorn, each of us hardly visible to the other in the thickening mist, save when the blaze of lightning flashed the scene into sudden and spectral clearness. At last we struck a rough mountain path, and five minutes later we lifted the latch of the hut.
