Here were huge mossy boulders, and red walls covered by lichens, and the air appeared dim and moist, and full of mellow, hollow roar.
Beyond this crossing the road descended the west side of the canyon, drawing away and higher from the creek.

Huge trees, the like of which Carley had never seen, began to stand majestically up out of the gorge, dwarfing the maples and white-spotted sycamores.

The driver called these great trees yellow pines.
At last the road led down from the steep slope to the floor of the canyon.

What from far above had appeared only a green timber-choked cleft proved from close relation to be a wide winding valley, tip and down, densely forested for the most part, yet having open glades and bisected from wall to wall by the creek.

Every quarter of a mile or so the road crossed the stream; and at these fords Carley again held on desperately and gazed out dubiously, for the creek was deep, swift, and full of bowlders.
