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 canyons 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 canyon 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 canyon, 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, ****** 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 canyon rim, growing on lean, rocky soil beneath mountain mahogany, nut pines, and junipers, beside dense flowery mats of Spiraea caespitosa and the beautiful pinnate-leaved Spiraea millefolia. The nut pine (Pinus edulis) scattered along the upper slopes and roofs of the canyon 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.
To civilized people from corn and cattle and wheat-field countries the canyon at first sight seems as uninhabitable as a glacier crevasse, utterly silent and barren. Nevertheless it is the home of the multitude of our fellow-mortals, men as well as animals and plants.
