As the day draws to a close, shadows, wondrous, black, and thick, like those of the morning, fill up the wall hollows, while the glowing rocks, their rough angles burned off, seem soft and hot to the heart as they stand submerged in purple haze, which now fills the cañon like a sea. Still deeper, richer, more divine grow the great walls and temples, until in the supreme flaming glory of sunset the whole cañon is transfigured, as if all the life and light of centuries of sunshine stored up and condensed in the rocks was now being poured forth as from one glorious fountain, flooding both earth and sky.
Strange to say, in the full white effulgence of the midday hours the bright colors grow dim and terrestrial in common gray haze; and the rocks, after the manner of mountains, seem to crouch and drowse and shrink to less than half their real stature, and have nothing to say to one, as if not at home. But it is fine to see how quickly they come to life and grow radiant and communicative as soon as a band of white clouds come floating by. As if shouting for joy, they seem to spring up to meet them in hearty salutation, eager to touch them and beg their blessings. It is just in the midst of these dull midday hours that the cañon clouds are born.
A good storm cloud full of lightning and rain on its way to its work on a sunny desert day is a glorious object. Across the cañon, opposite the hotel, is a little tributary of the Colorado called Bright Angel Creek. A fountain-cloud still better deserves the name “Angel of the Desert Wells”—clad in bright plumage, carrying cool shade and living water to countless animals and plants ready to perish, noble in form and gesture, seeming able for anything, pouring life-giving, wonder-working floods from its alabaster fountains, as if some sky-lake had broken. To every gulch and gorge on its favorite ground is given a passionate torrent, roaring, replying to the rejoicing lightning—stones, tons in weight, hurrying away as if frightened, showing something of the way Grand Cañon work is done. Most of the fertile summer clouds of the cañon are of this sort, massive, swelling cumuli, growing rapidly, displaying delicious tones of purple and gray in the hollows of their sun-beaten houses, showering favored areas of the heated landscape, and vanishing in an hour or two. Some, busy and thoughtful-looking, glide with beautiful motion along the middle of the cañon in flocks, turning aside here and there, lingering as if studying the needs of particular spots, exploring side cañons, peering into hollows like birds seeding nest-places, or hovering aloft on outspread wings. They scan all the red wilderness, dispensing their blessings of cool shadows and rain where the need is the greatest, refreshing the rocks, their offspring as well as the vegetation, continuing their sculpture, deepening gorges and sharpening peaks. Sometimes, blending all together, they weave a ceiling from rim to rim, perhaps opening a window here and there for sunshine to stream through, suddenly lighting some palace or temple and making it flare in the rain as if on fire.
Sometimes, as one sits gazing from a high, jutting promontory, the sky all clear, showing not the slightest wisp or penciling, a bright band of cumuli will appear suddenly, coming up the cañon in single file, as if tracing a well-known trail, passing in review, each in turn darting its lances and dropping its shower, making a row of little vertical rivers in the air above the big brown one. Others seem to grow from mere points, and fly high above the cañon, yet following its course for a long time, noiseless, as if hunting, then suddenly darting lightning at unseen marks, and hurrying on. Or they loiter here and there as if idle, like laborers out of work, waiting to be hired.
Half a dozen or more showers may oftentimes be seen falling at once, while far the greater part of the sky is in sunshine, and not a raindrop comes nigh one. These thundershowers from as many separate clouds, looking like wisps of long hair, may vary greatly in effects. The pale, faint streaks are showers that fail to reach the ground, being evaporated on the way down through the dry, thirsty air, like streams in deserts. Many, on the other hand, which in the distance seem insignificant, are really heavy rain, however local; these are the gray wisps well zigzagged with lightning. The darker ones are torrent rain, which on broad, steep slopes of favorable conformation give rise to so-called “cloudbursts”; and wonderful is the commotion they cause. The gorges and gulches below them, usually dry, break out in loud uproar, with a sudden downrush of muddy, boulder-laden floods. Down they all go in one simultaneous gush, roaring like lions rudely awakened, each of the tawny brood actually kicking up a dust at the first onset.
During the winter months snow falls over all the high plateau, usually to a considerable depth, whitening the rim and the roofs of the cañon buildings. But last winter, when I arrived at Bright Angel in the middle of January, there was no snow in sight, and the ground was dry, greatly to my disappointment, for I had made the trip mainly to see the cañon in its winter garb. Soothingly I was informed that this was an exceptional season, and that the good snow might arrive at any time. After waiting a few days, I gladly hailed a broad-browed cloud coming grandly on from the west in big promising blackness, very unlike the white sailors of the summer skies. Under the lee of a rim-ledge, with another snow-lover, I watched its movements as it took possession of the cañon and all the adjacent region in sight. Trailing its gray fringes over the spiry tops of the great temples and towers, it gradually settled lower, embracing them all with ineffable kindness and gentleness of touch, and fondled the little cedars and pines as they quivered eagerly in the wind like young birds begging their mothers to feed them. The first flakes and crystals began to fly about noon, sweeping straight up the middle of the cañon, and swirling in magnificent eddies along the sides. Gradually the hearty swarms closed their ranks, and all the cañon was lost in gray bloom except a short section of the wall and a few trees beside us, which looked glad with snow in their needles and about their feet as they leaned out over the gulf. Suddenly the storm opened with magical effect to the north over the cañon of Bright Angel Creek, inclosing a sunlit mass of the cañon architecture, spanned by great white concentric arches of cloud like the bows of a silvery aurora. Above these and a little back of them was a series of upboiling purple clouds, and high above all, in the background, a range of noble cumuli towered aloft like snow-laden mountains, their pure pearl bosses flooded with sunshine. The whole noble picture, calmly glowing, was framed in thick gray gloom, which soon closed over it; and the storm went on, opening and closing until night covered all.
Two days later, when we were on a jutting point about eighteen miles east of Bright Angel and one thousand feet higher, we enjoyed another storm of equal glory as to cloud effects, though only a few inches of snow fell. Before the storm began we had a magnificent view of this grander upper part of the cañon and also of the Coconino Forest and the Painted Desert. The march of the clouds with their storm banners flying over this sublime landscape was unspeakably glorious, and so also was the breaking up of the storm next morning—the mingling of silver-capped rock, sunshine, and cloud.
Most tourists make out to be in a hurry even here; therefore their days or hours would be best spent on the promontories nearest the hotel. Yet a surprising number go down the Bright Angel Trail to the brink of the inner gloomy granite gorge overlooking the river. Deep cañons attract like high mountains; the deeper they are, the more surely are we drawn into them. On foot, of course, there is no danger whatever, and, with ordinary precautions, but little on animals. In comfortable tourist faith, unthinking, unfearing, down go men, women, and children on whatever is offered, horse, mule, or burro, as if saying with Jean Paul, “fear nothing but fear”—not without reason, for these cañon trails down the stairways of the gods are less dangerous than they seem, less dangerous than home stairs. The guides are cautious, and so are the experienced, much-enduring beasts. The scrawniest Rosinantes and wizened-rat mules cling hard to the rocks endwise or sidewise, like lizards or ants. From terrace to terrace, climate to climate, down one creeps in sun and shade, through gorge and gully and grassy ravine, and, after a long scramble on foot, at last beneath the mighty cliffs one comes to the grand, roaring river.
To the mountaineer the depth of the cañon, from five thousand to six thousand feet, will not seem so very wonderful, for he has often explored others that are about as deep. But the most experienced will be awestruck by the vast extent of huge rock monuments of pointed masonry built up in regular courses towering above, beneath, and round about him. By the Bright Angel Trail the last fifteen hundred feet of the descent to the river has to be made afoot down the gorge of Indian Garden Creek. Most of the visitors do not like this part, and are content to stop at the end of the horse trail and look down on the dull-brown flood from the edge of the Indian Garden Plateau. By the new Hance Trail, excepting a few daringly steep spots, you can ride all the way to the river, where there is a good spacious camp-ground in a mesquite grove. This trail, built by brave Hance, begins on the highest part of the rim, eight thousand feet above the sea, a thousand feet higher than the head of Bright Angel Trail, and the descent is a little over six thousand feet, through a wonderful variety of climate and life. Often late in the fall, when frosty winds are blowing and snow is flying at one end of the trail, tender plants are blooming in balmy summer weather at the other. The trip down and up can be made afoot easily in a day. In this way one is free to observe the scenery and vegetation, instead of merely clinging to his animal and watching its steps. But all who have time should go prepared to camp awhile on the riverbank, to rest and learn something about the plants and animals and the mighty flood roaring past. In cool, shady amphitheaters at the head of the trail there are groves of white silver fir and Douglas spruce, with ferns and saxifrages that recall snowy mountains; below these, yellow pine, nut pine, juniper, hop-hornbeam, ash, maple, holly-leaved berberis, cowania, spiraea, dwarf oak, and other small shrubs and trees. In dry gulches and on taluses and sun-beaten crags are sparsely scattered yuccas, cactuses, agave, etc. Where springs gush from the rocks there are willow thickets, grassy flats, and bright, flowery gardens, and in the hottest recesses the delicate abronia, mesquite, woody compositae, and arborescent cactuses.
The most striking and characteristic part of this widely varied vegetation are the cactaceae—strange, leafless, old-fashioned plants with beautiful flowers and fruit, in every way able and admirable. While grimly defending themselves with innumerable barbed spears, they offer both food and drink to man and beast. Their juicy globes and disks and fluted cylindrical columns are almost the only desert wells that never go dry, and they always seem to rejoice the more and grow plumper and juicier the hotter the sunshine and sand. Some are spherical, like rolled-up porcupines, crouching in rock-hollows beneath a mist of gray lances, unmoved by the wildest winds. Others, standing as erect as bushes and trees or tall branchless pillars crowned with magnificent flowers, their prickly armor sparkling, look boldly abroad over the glaring desert, making the strangest forests ever seen or dreamed of. Cereus giganteus, the grim chief of the desert tribe, is often thirty or forty feet high in southern Arizona. Several species of tree yuccas in the same desert, laden in early spring with superb white lilies, form forests hardly less wonderful, though here they grow singly or in small lonely groves. The low, almost stemless Yucca baccata, with beautiful lily flowers and sweet banana-like fruit, prized by the Indians, is common along the cañon rim, growing on lean, rocky soil beneath mountain mahogany, nut pines, and junipers, beside dense flowery mats of Spiræa cæspitosa and the beautiful pinnate-leaved Spiræa millefolia. The nut pine (Pinus edulis) scattered along the upper slopes and roofs of the cañon buildings, is the principal tree of the strange dwarf Coconino Forest. It is a picturesque stub of a pine about twenty-five feet high, usually with dead, lichened limbs thrust through its rounded head, and grows on crags and fissured rock tables, braving heat and frost, snow and drought, and continuing patiently, faithfully fruitful for centuries. Indians and insects and almost every desert bird and beast come to it to be fed.
