Carley smiled her thanks, and, taking to the trail, she stepped out briskly, now giving attention to her surroundings. The canyon had widened, and the creek with its deep thicket of green and white had sheered to the left. On her right the canyon wall appeared to be lifting higher—and higher. She could not see it well, owing to intervening treetops. The trail led her through a grove of maples and sycamores, out into an open park-like bench that turned to the right toward the cliff. Suddenly Carley saw a break in the red wall. It was the intersecting canyon, West Fork. What a narrow red-walled gateway! Huge pine trees spread wide gnarled branches over her head. The wind made soft rush in their tops, sending the brown needles lightly on the air. Carley turned the bulging corner, to be halted by a magnificent spectacle. It seemed a mountain wall loomed over her. It was the western side of this canyon, so lofty that Carley had to tip back her head to see the top. She swept her astonished gaze down the face of this tremendous red mountain wall and then slowly swept it upward again. This phenomenon of a cliff seemed beyond the comprehension of her sight. It looked a mile high. The few trees along its bold rampart resembled short spear-pointed bushes outlined against the steel gray of sky. Ledges, caves, seams, cracks, fissures, beetling red brows, yellow crumbling crags, benches of green growths and niches choked with brush, and bold points where single lonely pine trees grew perilously, and blank walls a thousand feet across their shadowed faces—these features gradually took shape in Carley’s confused sight, until the colossal mountain front stood up before her in all its strange, wild, magnificent ruggedness and beauty.

“Arizona! Perhaps this is what he meant,” murmured Carley. “I never dreamed of anything like this.... But, oh! it overshadows me—bears me down! I could never have a moment’s peace under it.”

It fascinated her. There were inaccessible ledges that haunted her with their remote fastnesses. How wonderful would it be to get there, rest there, if that were possible! But only eagles could reach them. There were places, then, that the desecrating hands of man could not touch. The dark caves were mystically potent in their vacant staring out at the world beneath them. The crumbling crags, the toppling ledges, the leaning rocks all threatened to come thundering down at the breath of wind. How deep and soft the red color in contrast with the green! How splendid the sheer bold uplift of gigantic steps! Carley found herself marveling at the forces that had so rudely, violently, and grandly left this monument to nature.

“Well, old Fifth Avenue gadder!” called a gay voice. “If the back wall of my yard so halts you—what will you ever do when you see the Painted Desert, or climb Sunset Peak, or look down into the Grand Canyon?”

“Oh, Glenn, where are you?” cried Carley, gazing everywhere near at hand. But he was farther away. The clearness of his voice had deceived her. Presently she espied him a little distance away, across a creek she had not before noticed.

“Come on,” he called. “I want to see you cross the stepping stones.”

Carley ran ahead, down a little slope of clean red rock, to the shore of the green water. It was clear, swift, deep in some places and shallow in others, with white wreathes or ripples around the rocks evidently placed there as a means to cross. Carley drew back aghast.

“Glenn, I could never make it,” she called.

“Come on, my Alpine climber,” he taunted. “Will you let Arizona daunt you?”

“Do you want me to fall in and catch cold?” she cried, desperately.
