A short distance above the head of the fall the river gives off a small part of its waters, which, descending a narrow canyon to the north of the fall, along the base of the Liberty Cap, forms a beautiful cascade, and finally joins the main stream again a few yards below the fall. Sometime ago the officer in charge of the valley seemed to regard the cascades as so much waste water, inasmuch as they employed an enterprising and ingenious gentleman to "fix the falls," as he said, by building a dam across the cascade stream where it leaves the river, so as to make all the water tumble and sing together. No great damage was done, however, by this dam or any other improvement. Mending the Yosemite waterfalls would seem to be about the last branch of industry that even unsentimental Yankees seeking new outlets for enterprise would be likely to engage in. As well whitewash the storm-stained face of El Capitan or gild the domes.
The Vernal Fall is a general favorite among the visitors to the valley, doubtless because it is better seen and heard than any of the others, on account of its being more accessible. A good stairway leads up the cliffs alongside of it, and the open level plateau over the edge of which it enables one to saunter in safety close to its brow and watch its falling waters as they gradually change from green to purplish grey and white, until broken into spray at the bottom. It is the most staid and orderly of all the great falls, and never shows any marked originality of form or behavior. After resting in Emerald Pool, the river glides calmly over the smooth lip of a perfectly plain and sheer precipice, and descends in a regular sheet about 80 feet wide, striking upon a rough talus with a steady, continuous roar that is but little influenced by the winds that sweep the cliffs. Thus it offers in every way a striking contrast to the impetuous Nevada, which so crowds and hurries its chafed and twisted waters over the verge, which seemingly are glad to escape, as they plunge free in the air, while their deep, booming tones go sounding far out over the listening landscape.
From the foot of the Vernal the river descends to its confluence with the Illilouette Creek in a tumultuous rush and roar of cascades, and emerges from its shadowy, boulder-choked canyon in a beautiful reach of rapids, stately spaces forming a wall on either side; while the flowering dogwood, rubus nutkanus, azalea, and tall, plumy ferns, well watered and cool, make beautiful borders. Through the open, sunny levels of the meadows it flows with a clear, foamless current, swelled by its Tenaya and Yosemite Creek tributaries, keeping calm and transparent until nearly opposite the Bridal Veil Fall, where it breaks into grey rapids in crossing a moraine dam. In taking leave of the valley, the river makes another magnificent stretch of cascades and rapids on its way down its lower canyon, a fine view of which may be had from the Coulterville road that runs across the bottom of a rough talus close alongside the massy surging flood, and past the beautiful Cascade Fall.
Climbing the great Half Dome is fine Yosemite exercise. With the exception of a few minor spires and pinnacles, the Dome is the only rock about the valley that is strictly inaccessible without artificial means, and its inaccessibility is expressed in very severe and simple terms. But longing eyes were nonetheless fixed on its noble brow, until at length, in the year 1875, George Anderson, an indomitable Scotchman, succeeded in making a way to the summit. The side facing the Tenaya Canyon is an absolutely vertical precipice from the summit to a depth of about 1,600 feet, and on the opposite side it is nearly vertical for about as great a depth. The southwest side presents a very steep and finely drawn curve from the top down a thousand feet or more, while on the northeast where it is united with the Clouds Rest Ridge, one may easily reach the Saddle, within 700 feet of the summit, where it rises in a smooth, graceful curve a few degrees too steep for unaided climbing.
A year or two before Anderson gained the summit, John Conway, a resident of the valley, and his son, excellent mountaineers, attempted to reach the top from the Saddle by climbing barefooted up the grand curve with a rope which they fastened at irregular intervals by means of eye-bolts driven into joints of the rock. But, finding that the upper portion of the curve would require laborious drilling, they abandoned the attempt, glad to escape from the dangerous position they had reached, some 300 feet above the Saddle.
Anderson began with Conway's old rope, which had been left in place, and resolutely drilled his way to the top inserting eye-bolts five to six feet apart, and making his rope fast to each in succession, resting his feet on the last bolt while he drilled a hole for the next above. Occasionally some irregularity in the curve or slight foothold, would enable him to climb a few feet without the rope, which he would pass and begin drilling again, and thus the whole work was accomplished in less than a week. Notwithstanding the enthusiastic eagerness of tourists to reach the crown of the Dome, the views of the valley from this lofty standpoint are far less striking than from many other points comparatively low, chiefly on account of the foreshortening effect produced by looking down from so great a height. The North Dome is dwarfed almost beyond recognition, the grand sculpture of the Royal Arches may not be noticed at all, and the whole range of the walls on both sides seem comparatively low and sunken, especially when the valley is flooded with noonday sunshine; while the Dome itself, the most sublime feature of all general views of Yosemite, is beneath one's feet. Little Yosemite Valley is well seen, but a better view of it may be obtained from the base of the Starr King cone. The summit landscapes, however, toward Mounts Ritter, Lyell, and Dana, are very effective and grand. My first view from the top of the Dome, in November, after the first winter snow had fallen on the mountains, was truly glorious. A massive cloud of pure pearl luster was arched across the valley, from wall to wall, one end resting on the grand abutment of El Capitan, the other on Cathedral Rock, apparently as fixed and calm as the brown meadow and groves in the shadow beneath it. Then, as I stood on the tremendous verge overlooking Mirror Lake, a flock of smaller clouds, white as snow came swiftly from the north, trailing over the dark forests and, arriving on the brink of the valley, descended with imposing gestures through Indian Canyon and over the Arches and North Dome. On they came with stately deliberation, nearer, nearer, gathering and massing beneath my feet, and filling the Tenaya abyss. Then the sun shone free, painting them with rainbow colors and making them bum on the edges with glorious brightness. It was one of those brooding, changeful days that come just between the Indian summer and winter, when the leaf colors begin to grow dim and the clouds come and go, moving about among the cliffs like living creatures; now hovering aloft in the tranquil sky, now caressing rugged rock-brows with infinite gentleness, or, wandering afar over the tops of the forests, touch the spires of fir and pine with their soft silken fringes as if telling the coming of the snow. Now and then the valley appeared all bright and cloudless, with its crystal river wavering and shimmering through meadow and grove, while to the eastward the white peaks rose in glorious array keenly outlined on the dark blue sky; then the clouds would gather again, wreathing the Dome and making a darkness like night.
On the crown of the Dome, notwithstanding its severely bare appearance, there are four clumps of pines representing three species; Pinus albicaulis, P. contorta, and P. ponderosa, var. Jeffreyi, all three repressed and stormbeaten. The alpine spiraea grows there also, and blooms freely with potentilla, ivesia, erigeron, solidago, pentstemon, eriogonum, and four or five species of grasses and sedges, like those of other granite summits of the same elevation.
When the all-embracing ice-mantle of the Glacial Period began to grow thin and form separate glaciers that flowed like rivers in the canyons, Half Dome was probably the first of the Yosemite rocks to emerge from the ice, burnished and glowing like a crystal. Centuries of storms have passed over it since first it came to light, but it still remains a telling monument of the glaciers that brought it into relief from the general mass of the range. Its flinty surface, scarcely at all wasted, is covered with glacial inscriptions from base to crown, and the meaning of these is the reward of all who devoutly study them.
The quick, smart visitor to the valley who buys his ticket early, determined to take the water-falls by the forelock, when their streaming manes are whitest, and when the flooded meadows are covered with mirrors, can have but dim conceptions of the beauties of the peaceful yellow autumn
