Down and down we toiled. And now the stream-bed was bare of boulders and the banks of earth. The floods that had rolled down that canyon had here borne away every loose thing. All the floor, in places, was bare red and white stone, polished, glistening, slippery, affording treacherous foothold. And the time came when Wetherill abandoned the stream-bed to take to the rock-strewn and cactus-covered ledges above.
The canyon widened ahead into a great ragged iron-lined amphitheater, and then apparently turned abruptly at right angles. Sunset rimmed the walls.
I had been tired for a long time and now I began to limp and lag. I wondered what on earth would make Wetherill and the Indians tired. It was with great pleasure that I observed the giant Joe Lee plodding slowly along. And when I glanced behind at my straggling party it was with both admiration for their gameness and glee for their disheveled and weary appearance. Finally I got so that all I could do was to drag myself onward with eyes down on the rough ground. In this way I kept on until I heard Wetherill call me. He had stopped—was waiting for me. The dark and silent Indian stood beside him, looking down the canyon.
I saw past the vast jutting wall that had obstructed my view. A mile beyond, all was bright with the colors of sunset, and spanning the canyon in the graceful shape and beautiful hues of the rainbow was a magnificent natural bridge.
"Nonnezoshe," said Wetherill, simply.
This rainbow bridge was the one great natural phenomenon, the one grand spectacle which I had ever seen that did not at first give vague disappointment, a confounding of reality, a disenchantment of contrast with what the mind had conceived.
But this thing was glorious. It absolutely silenced me. My body and brain, weary and dull from the toil of travel, received a singular and revivifying freshness. I had a strange, mystic perception that this rosy-hued, tremendous arch of stone was a goal I had failed to reach in some former life, but had now found. Here was a rainbow magnified even beyond dreams, a thing not transparent and ethereal, but solidified, a work of ages, sweeping up majestically from the red walls, its iris-hued arch against the blue sky.
