Mountaineering in the Sierra Nevada. Clarence King
Brewer determined to make this camp a home for the week during which we were to explore and study all about the neighborhood. We were on a great granite spur, sixty miles from east to west by twenty miles wide, which lies between the Kaweah and King’s River cañons. Rising in bold sweeps from the plain, this ridge joins the Sierra summit in the midst of a high group. Experience had taught us that the cañons are impassable by animals for any great distance; so the plan of campaign was to find a way up over the rocky crest of the spur as far as mules could go.
In the little excursions from this camp, which were made usually on horseback, we became acquainted with the forest, and got a good knowledge of the topography of a considerable region. On the heights above King’s Cañon are some singularly fine assemblies of trees. Cotter and I had ridden all one morning northeast from camp under the shadowy roof of forest, catching but occasional glimpses out over the plateau, until at last we emerged upon the bare surface of a ridge of granite, and came to the brink of a sharp precipice. Rocky crags lifted just east of us. The hour devoted to climbing them proved well spent.
A single little family of alpine firs growing in a niche in the granite surface, and partly sheltered by a rock, made the only shadow, and just shielded us from the intense light as we lay down by their roots. North and south, as far as the eye could reach, heaved the broad, green waves of plateau, swelling and merging through endless modulation of slope and form.
Conspicuous upon the horizon, about due east of us, was a tall, pyramidal mass of granite, trimmed with buttresses which radiated down from its crest, each one ornamented with fantastic spires of rock. Between the buttresses lay stripes of snow, banding the pale granite peak from crown to base. Upon the north side it fell off, grandly precipitous, into the deep upper cañon of King’s River. This gorge, after uniting a number of immense rocky amphitheatres, is carved deeply into the granite two and three thousand feet. In a slightly curved line from the summit it cuts westward through the plateau, its walls, for the most part, descending in sharp, bare slopes, or lines of ragged débris, the resting-place of processions of pines. We ourselves were upon the brink of the south wall; three thousand feet below us lay the valley, a narrow, winding ribbon of green, in which, here and there, gleamed still reaches of the river. Wherever the bottom widened to a quarter or half a mile, green meadows and extensive groves occupied the level region. Upon every niche and crevice of the walls, up and down sweeping curves of easier descent, were grouped black companies of trees.
The behavior of the forest is observed most interestingly from these elevated points above the general face of the table-land. All over the gentle undulations of the more level country sweeps an unbroken covering of trees. Reaching the edge of the cañon precipices, they stand out in bold groups upon the brink, and climb all over the more ragged and broken surfaces of granite. Only the most smooth and abrupt precipices are bare. Here and there a little shelf of a foot or two in width, cracked into the face of the bluff, gives foothold to a family of pines, who twist their roots into its crevices and thrive. With no soil from which the roots may drink up moisture and absorb the slowly dissolved mineral particles, they live by breathing alone, moist vapors from the river below and the elements of the atmosphere affording them the substance of life.
I believe no one can study from an elevated lookout the length and depth of one of these great Sierra cañons without asking himself some profound geological questions. Your eyes range along one or the other wall. The average descent is immensely steep. Here and there side ravines break down the rim in deep, lateral gorges. Again, the wall advances in sharp, salient precipices, rising two or three thousand feet, sheer and naked, with all the air of a recent fracture. At times the two walls approach each other, standing in perpendicular gateways. Toward the summits the cañon grows, perhaps, a little broader, and more and more prominent lateral ravines open into it, until at last it receives the snow drainage of the summit, which descends through broad, rounded amphitheatres, separated from each other by sharp, castellated snow-clad ridges.
Looking down the course of the river, vertical precipices are seen to be less and less frequent, the walls inclining to each other more and more gently, until they roll out on the north and south in round, wooded ridges. Solid, massive granite forms the material throughout its whole length. If you study the topography upon the plateaus above one of these cañons, you will see that the ridges upon one side are reproduced in the other, as if the outlines of wavy table-land topography had been determined before the great cañon was made.
It is not easy to propose a solution for this peculiar structure. I think, however, it is safe to say that actual rending asunder of the mountain mass determined the main outlines. Upon no other theory can we account for those blank walls. Where, in the upper course of the cañon, they descend in a smooth, ship-like curve, and the rocks bear upon their curved sides the markings and striations of glaciers, it is easy to see that those terrible ice-engines gradually modified their form; and toward the foot-hills the forces of aqueous erosion are clearly indicated in the rounded forms and broad undulations of the two banks.
Looking back from our isolated crag in the direction of our morning’s ride, we saw the green hills break down into the basin of Thomas’s Mill, but the disc of meadow lay too deep to be seen. Forests, dense and unbroken, grew to the base of our cliff. The southern sunlight reflected from its polished foliage gave to this whole sea of spiry tops a peculiar golden green, through which we looked down among giant red and purple trunks upon beds of bright mountain flowers. As the afternoon lengthened, the summit rank of peaks glowed warmer and warmer under inclined rays. The granite flushed with rosy brightness between the fields of glittering golden snow. A mild, pearly haziness came gradually to obscure the ordinary cold-blue sky, and, settling into cañon depths, and among the vast, open corridors of the summit, veiled the savage sharpness of their details.
I lay several hours sketching the outlines of the summit, studying out the systems of alpine drainage, and getting acquainted with the long chain of peaks, that I might afterward know them from other points of view. I became convinced from the great apparent elevation and the wide fields of snow that we had not formerly deceived ourselves as to their great height. Warned at length by the deepening shadow in the King’s Cañon, by the heightened glow suffusing the peaks, and the deep purple tone of the level expanse of forest, all forerunners of twilight, we quitted our eyrie, crept carefully down over half-balanced blocks of débris to the horses, and, mounting, were soon headed homeward, in what seemed, by contrast, to be almost a nocturnal darkness.
Wherever the ground opened level before us we gave our horses the rein, and went at a free gallop through the forest; the animals realized that they were going home, and pressed forward with the greatest spirit. A good-sized log across our route seemed to be an object of special amusement to Kaweah, who seized the bits in his teeth, and, dancing up, crouched, and cleared it with a mighty bound, in a manner that was indeed inspiring, yet left one with the impression that once was enough of that sort of thing. Fearing some manner of hostilities with him, I did my very best to quiet Kaweah, and by the end of an hour had gotten him down to a sensible, serious walk. I noticed that he insisted upon following his tracks of the morning’s march, and was not contented unless I let him go on the old side of every tree. Thus I became so thoroughly convinced of his faculty to follow the morning’s trail that I yielded all control of him, giving myself up to the enjoyment of the dimly lighted wood.
