Aldous rode back to Joanne.
"It looks like rain," he explained. "These Pacific showers come up quickly this side of the Divide, and they drench you in a jiffy. Donald is going on ahead to put up a tent."
By the time they reached the mouth of the canyon MacDonald was out of sight. A little creek that was a swollen torrent in spring time trickled out of the gorge. Its channel was choked with a chaotic confusion of sandstone rock and broken slate, and up through this Aldous carefully picked his way, followed closely by Joanne. The sky continued to darken above them, until at last the sun died out, and a thick and almost palpable gloom began to envelop them. Low thunder rolled through the mountains in sullen, rumbling echoes. He looked back at Joanne, and was amazed to see her eyes shining, and a smile on her lips as she nodded at him.
"It makes me think of Henrik Hudson and his ten-pin players," she called softly. "And ahead of us—is Rip Van Winkle!"
The first big drops were beginning to fall when they came to an open place. The gorge swung to the right; on their left the rocks gave place to a rolling meadow of buffalo grass, and Aldous knew they had reached the basin. A hundred yards up the slope was a fringe of timber, and as he looked he saw smoke rising out of this. The sound of MacDonald's axe came to them. He turned to Joanne, and he saw that she understood. They were at their journey's end. Perhaps her fingers gripped her rein a little more tightly. Perhaps it was imagination that made him think there was a slight tremble in her voice when she said:
"This—is the place?"
"Yes. It should be just above the timber. I believe I can see the upper break of the little box canyon Keller told me about."
She rode without speaking until they entered the timber. They were just in time. As he lifted her down from her horse the clouds opened, and the rain fell in a deluge. Her hair was wet when he got her in the tent. MacDonald had spread out a number of blankets, but he had disappeared. Joanne sank down upon them with a little shiver. She looked up at Aldous. It was almost dark in the tent, and her eyes were glowing strangely. Over them the thunder crashed deafeningly. For a few minutes it was a continual roar, shaking the mountains with mighty reverberations that were like the explosions of giant guns. Aldous stood holding the untied flap against the beat of the rain. Twice he saw Joanne's lips form words. At last he heard her say:
"Where is Donald?"
He tied the flap, and dropped down on the edge of the blankets before he answered her.
