In the face of this common peril, personality called a truce, and she pushed on with him blindly, leaving it to him to choose the way and set the pace. But their own tracks down the incline had filled with incredible swiftness; soon they were completely effaced. And, when the noise subsided, he stopped and looked about him, bewildered. He saw nothing but a breadth of sharply dipping slope, white, smooth as an unwritten scroll, over which hung the swaying, voluminous veil of the falling snow. He put his hands to his mouth then, and lifted his voice in a great hail. It brought no reply, but in the moment he waited, somewhere far below in those obscured depths, a great tree, splitting under tremendous pressure, crashed down, then quickly the terrific sweep and roar of a second mightier avalanche filled the hidden gorge. Morganstein caught her arm once more. "We must get back to that shoulder where it's safe," he shouted. "Banks will come to look us up." After that, as they struggled on up the slope, he fell to saying over and over, as long as the reverberations lasted: "Almighty God!" As they ascended, the snow fell less heavily and finally ceased. It became firm underfoot, and a cross wind, starting in puffs, struck their faces sharply with a promise of frost. Then strange hummocks began to rise. They were upheavals of ice, shrouded in snow. Sometimes a higher one presented a sheer front shading to bluish-green. They had not passed this point with Banks, but Morganstein shaped a course to a black pinnacle, lifting through the mist beyond, that he believed was the crag at the shoulder. She stumbled repeatedly on the rough surface. Her labored breathing in the great stillness, like the beat of a pendulum in an empty house, tried his strained nerves. He upbraided her for leaving her alpenstock down the slope. But she paid no attention. She looked back constantly; she was like a woman being led away from a locked door, moving reluctantly, listening against hope for a word or sign. So, at last, they came to the rock. It was not the crag, but a hanging promontory, where the mountain broke in a three-sided precipice. The cloud surged around it like an unplumbed sea.
