The light in the east was a pale gold under a steely green-blue sky.

All the abyss of the Canyon was soft, gray, transparent, and the belt of gold broadened downward, making shadows on the west slopes of the mesas and escarpments.

Far down in the shadows she discerned the river, yellow, turgid, palely gleaming.

By straining her ears Carley heard a low dull roar as of distant storm.

She stood fearfully at the extreme edge of a stupendous cliff, where it sheered dark and forbidding, down and down, into what seemed red and boundless depths of Hades.
