From such a vantage it would instantly appear how distinct are the Nevadas (nieve, snowy) among the Sierras of California. A very Bonaparte of mountains, new-born and lording it over the ancient ranges, not content with its vast empery but swinging north into the unpre-empted icy regions. San Bernardino and San Jacinto are as far from it as the Faubourg St. Germain from an island in the sea. Sierra Madre is of the Coast Range; Shasta a fire-hole, a revolutionist; the true Sierra is the midriff of a continent. From its northern extremity one sees the sun in a circle and the Northern Lights; that portion of it we know as Sierra Nevada swings into the state above Honey Lake, and ends southward in a tumble of blunt peaks below Kern River. This is quite enough, however, for Californians to make free with, and more than they can appreciate.
Geographically the range begins on the south at Tehachapi, but at Walker's Pass, a day's journey to the north, is the first appearance of its most salient characteristic, the great Sierra Fault. In its youth the range suffered incredible cataclysms. For two hundred miles the great eastern plain dropped; weighted as it was with its withered aristocracy of hills—how weazened and old you can see to this day—it tore sharply downward, and the depth of that fall from the heaven-affronting peak of Whitney to the desert valley of Inyo is a matter of two miles of sheer descent.
The whole Sierra along the line of faultage has the contour of a wave about to break. It swings up in long water-shaped lines from the valley of the San Joaquin, and rears its jagged crest above the abrupt desert shore. Seen from close under, some of these two- and three-thousand-foot precipices have the pitch of toppling waters. As they rose new-riven from the earth their proportions must have been more than terrifying.
Later the Ice Age bore downward from the north, and through immeasurable years carved the fractured granite into shapes of enduring beauty. It rounded the great jutting fronts, it insured them against the tooth of time with the keen icy polish with which they shine still against the morning. It gouged narrow wall-sided cañons, cut the course of rivers, and sinking like a graver's tool into the heart of the range, scooped out deep wells of pleasantness. Afterward, when the ice was old, it must have moved more slowly, for the lines it left, retreating northward, are more flowing, the hill-crowns rounder. And then the mountain was besieged with trees. They stormed it, scaled its free precipices; you can see by the thick mould of the valleys what ranks and ranks of them went down, and along the snow-line how by the persistence of assault they are bent and contorted.
This is the whole effect of the sombre swathes of pine that mask the Sierra slopes. They march along the water-courses, they climb up sheer precipices in staggering files, trooping in the passes; across the smooth meadow spaces they lock arms, they await the word of command. By a very little observation they are seen to be ranged in orderly companies. Here a warm current of air travelling steadily from the superheated valleys carries the life zone higher, there a defiant bony ridge drops it a few thousand feet, but the relative arrangement of species does not greatly vary. The broad oaks, like reverend grandsires, from the foothills see the procession go by, they follow as far as the gates of the mountain, crutched and bowed. All the lower cañons are full of a rabble of deciduous trees, chinquapins, scrub oak, madroño, full of gay camp-followers, lilac, dogwood, azaleas, strumpet penstemons, flaunting lupins, monk's-hood, columbine.
YOSEMITE FALLS
The grey nut pine, wide-branched, unwarlike but serviceable, opens the ranks of conifers. Then the long-leaved pines begin, ponderoso, Coulteri, and the slender, arrowy, fire-resisting attenuata. On the western slope, increasing as they go northward, the redwood holds all the open country, but it is no climber like monticola, the largest of all true pines, the captain of the Sierra forests. The firs usurp the water-borders and the low moraines; clannish, incommunicable, they seem not to find it worth while to grow unless they grow stately. Above all these range the thin-barked pines, the lodgepole, Douglas spruce, librocedrus, and hardy junipers in windy passes. About the meadows and lake-borders the quaking asps push like children between the knees along the line; and highest, most persistent, the creeping-limbed, wind-depressed white-barked pine, under whose matted boughs the wild sheep bed.
The trees have each their own voice—a degree of flexibility or length of needles upon which the wind harps to produce its characteristic note. The traveller in the dark of mountain nights knows his way among them as by the street cries of his own city. The creaking of the firs, the sough of the long-leaved pines, the whispering whistle of the lodgepole pine, the delicate frou-frou of the redwoods in a wind, these come out for him in the darkness with the night scent of moth-haunted flowers. But there is one tree that for the footer of the mountain trails is voiceless; it speaks no doubt, but it speaks only to the austere mountain-heads, to the mindful winds and the watching stars. It speaks as men speak to one another and are not heard by the little ants crawling over their boots. This is the "big tree," the sequoia. In something less than a score of forest patches about the rim of the Twin Valleys, the sequoia abides, out of some possible preglacial period, out of some past of which nothing is left to us but the fading memory of the "giants in those days." The age of individual big trees can be computed in terms of human history. There are evidences written in the rings of these that they endured the drouth which made the famine in the days of Ahab the king, against which Elijah prayed. These are growing trees whose seeds are fertile.
