e began his climb at a point five miles away. The slopes that seemed smooth and hard from a distance became, at closer range, a place of wind-heaped, sandy ash, carved and scoured into fantastic forms. But its very roughness offered protection, and Rawson fought the dragging sand, and the gray, choking ash that dried his throat and cut it like emery, without fear of being observed.
He fought against time, too. Above Little Rhyolite, whatever mysterious men were making the ascent would find the going easy. There were windswept areas, long fields of pumice; a man could make good time there. Rawson had none of these to aid him. He cast anxious glances toward the eastern sky as he struggled on, till he saw gray light change to rose and gold—but he stood in the titanic cleft in the crater's rim as the first straight rays of the sun struck across.
The volcano's top had been stripped clean by the winds of countless years. Rocks, black, brown, even blood-red, were naked to the pitiless glare of the sun. Their colors were mingled in a weird fantasy of twisted lines that told of the inferno of heat in which they had been formed.
They towered high above the head of Dean Rawson as he stood, panting and trembling with exhaustion. The cleft before him had become enormous: it was a canyon, half filled with pumice and coarse ash.
awson stood for long minutes in quiet listening. At the canyon's end would lie the crater, and in that crater he would find.... But there was no slightest picture in his mind of what he might see. He knew only that he himself must remain unseen. He went forward cautiously.
Rocky walls; a floor of sand where his feet left no mark. He was watching ahead and above him. His gun was ready in his hand; he did not propose to be ambushed. He moved with never a sound.
The silence persisted; no living thing other than himself lent any flicker of motion to the scene. Not even a lizard could hope for existence amid these dead and barren heights. He was alone—the certainty of it had driven deeply into his mind before the canyon end was reached. And, desert man though he was and accustomed to traveling the waste places of the earth, Rawson learned a new meaning and depth of solitude.
Here was no voiceless companionship of trees or brush or cactus; no little living things scuttled across the rocks—he was alone, the only speck of life in a place where life seemed forbidden.
