here in profusion and blooms in September, long after the warmer thickets down the valley have withered and gone to seed. Even close to the fall, and behind it at the base of the cliff, a few venturesome plants may be found, undisturbed by the rockshaking torrent.
The basin at the foot of the fall into which the current directly pours when it is not swayed by the wind is about ten feet deep, and fifteen to twenty feet in diameter. That it is not much deeper is surprising, when the great height and force of the fall is considered. But the rock where the water strikes probably suffers much less erosion than it would were the descent less than half as great, since the current is outspread, and much of its force is spent ere it reaches the bottom; being received on the air as upon an elastic cushion, and borne outward and dissipated over a surface more than fifty yards wide.
This surface, easily examined when the water is low, is intensely clean and fresh-looking. It is the raw, quick flesh of the mountain wholly untouched by the weather. In summer droughts, when the snowfall of the preceding winter has been light, the fall is reduced to a mere shower of separate drops without any obscuring spray. Then we may safely go to the back of the fall and view the crystal shower from beneath, which, when the sun is shining, is extremely beautiful, each drop wavering and pulsing as it makes its way through the air, and flashing off jets of colored light of ravishing beauty. But all this is invisible from the bottom of the valley, like a thousand other interesting things. One must labor for beauty as for bread here as elsewhere.
During the time of spring floods the best near view of the fall is obtained from a ledge on the east side above the blinding spray, at a height of about 400 feet from the base of the fall. A climb of about 1,400 feet from the valley has to be made, and there is no trail, but to anyone fond of climbing, and who is at all stirred by a love of adventure, this will make the ascent all the more delightful. The ledge runs out back of the fall on the sheer front of the cliff, so that the fall may be approached as closely as we wish. When the afternoon sunshine is streaming through the thronging masses of down-rushing waters the marvelous firmness and variety of their forms are beautifully revealed. The whole fall is a majestic column of foaming, snowy water, ever wasting, ever renewed. At the top it seems to burst forth from some grand, throbbing heart of the mountain in irregular pulses, comet-like spurts succeeding one another in sublime rhythm. Now and then one mighty throb sends forth a mass into the free air far beyond the others, which rushes alone to the bottom of the fall with long, streaming, tail-like, combed silk, illumined by the sun, while the others, descending in clusters, gradually mingle and lose their identity. They rush past with amazing velocity and display of power, though apparently drowsy and deliberate in their movements when observed from the bottom of the valley at a distance of a mile or two. The heads of these comet-like masses are composed of nearly solid water, and are dense white in color, like pressed snow, from the friction they suffer in rushing through the air, the portion worn off forming the tail, between the white lustrous threads and films of which, faint, greyish pencillings appear, while the outer, finer sprays of waste water-dust, whirling in sunny eddies, are pearl grey throughout.
At the bottom of the fall there is but little distinction of form visible. It is mostly a driving, boiling, upswirling mass of scud and spray, through which the light sifts in grey and purple tones, while at times, when the sun strikes at the required angle, the whole is changed to brilliant rainbow hues. The middle portion of the fall is the most openly beautiful; lower, the various forms into which the waters are wrought are more closely and voluminously veiled, while higher, towards the head, the current is more simple and compact. But even at the bottom, in the boiling clouds of spray, there is no confusion, while the rainbow light makes all divine, adding glorious beauty and peace to glorious power. The Upper Yosemite Fall has far the richest, as well as the most powerful voice of all the falls of the valley, its tones varying from the sharp hiss and rustle of the wind in the glossy leaves of the live oaks and the soft, sifting, hushing tones of the pines, to the loudest rush and roar of storm-winds and thunder among the crags of the summit peaks. The low bass, booming, reverberating tones, heard under favorable circumstances five or six miles away, are formed by the dashing and exploding of heavy masses of water and air upon two projecting ledges on the cliff, 400 and 600 feet above the base of the fall. The torrent of massive comets is continuous at time of high water, while the explosive, booming, notes are wildly intermittent, because, unless influenced by the wind, most of the heavier masses shoot out from the face of the precipice, and pass the ledges upon which at other times they are wrecked. Occasionally the whole fall is swayed away from the front of the cliff, then suddenly clashed flat against it, or vibrated from side to side like a pendulum, giving rise to endless variety of forms and sounds.
Once during a violent wind-storm, while I watched the fall from the shelter of a pine-tree, the whole ponderous column was suddenly arrested in its descent at a point about midway between the base and top, and was neither blown upward or turned aside, but simply held stationary in mid-air as if gravitation below that point had ceased to act. Thus it remained for more than a minute, resting in the arms of the stormwind, the usual quantity of water meanwhile coming over the brow of the cliff and accumulating in the air as if falling upon an invisible floor, swedging and widening. Then, as if commanded to go on, scores of arrowy water-comets shot forth from the base of the suspended fountain, and the grand anthem of the fall once more began to sound. After bathing so long in the spray of the fall it is natural to look above and beyond it and say: "Where does all this chanting water come from?" This is easily learned by going and seeing.
The Yosemite Creek is the most tranquil of all the larger streams that pour over the valley walls. The others, while yet a good way back from the verge of the valley, abound in loud-voiced falls and cascades or rushing rapids, but Yosemite Creek, as if husbanding its resources, after the descent of its main tributaries from the snowy heights of the Hoffman Range, flows quietly on through strips of level meadow and smooth hollows and flats, with only a few small cascades, showing nothing in all its course to suggest the grandeur of its unrivaled falls in the valley.
Its wide and shallow basin is so crowded with domes it seems paved with them. Some castellated piles adorn its western rim, while the great Tuolumne Canyon sweeps past it on the north, and the cool, shadow-covered precipices of the Hoffman Range bound it on the east and northeast. During winter and spring most of the waters of the basin are derived directly from snow, but in summer only two or three, and in the drier seasons only one of its many streams draws its source from perennial fountains of snow and ice. Then the main dependence of the many tributaries are moraines of the ancient glaciers, in which a part of the melting snows and rains are absorbed.
Issuing from their moraine fountains, each shining thread of water at once begins to sing, running gladly onward, over boulders, over rock-stairs, over dams of fallen trees; now groping in shadows, now gliding free in the light on glacier-planed pavements, not a leaf on their borders; diving under willows, fingering their red roots and low-dipping branches, then absorbed in green bogs; out again among mosaics of leaf, shadows and light, whirling in pools giddy and ruffled, then restful and calm, not a foambell in sight; whispering low, solemn in gestures as full grown rivers, slowly meandering through green velvet meadows, banks embossed with bryanthus and yet finer cassiope, white and blue violets blending with white and blue daisies in smooth, silky sods of the Alpine agrostis; out again on bare granite, flowing over gravel and sand mixed with mica and garnets and white crystal quartz, making tiny falls and cascades in rapid succession, until at length all the bright, rejoicing choir meet together to form the main stream which flows calmly down to its fate in the valley, sweeping over the tremendous verge beneath a mantle of diamond spray. Amid the varied foams and fine ground mists of the mountain streams that are ever rising from a thousand waterfalls, there is an affluence and variety of rainbows scarce at all known to the careworn visitor from the lowlands. Both day and night, winter and summer, this divine light may be seen wherever water is falling in spray and foam, a silent interpreter of the heart-peace of nature, amid the wildest displays of her power. In the bright spring mornings the black-walled recess at the foot of the Lower Yosemite Fall is lavishly filled with irised spray, which does not simply span the dashing foam, but the foam itself, the whole mass of it, seems to be colored, and drifts and wavers, mingling with the foliage of the adjacent trees, without suggesting any relationship to the ordinary rainbow. This is perhaps the largest and most reservoir-like accumulation of iris color to be found in the valley.
