STEEP TRAILS: Adventure Memoirs, Travel Sketches, Nature Essays & Wilderness Studies. John Muir

strength of the ice, I seemed to walk mysteriously, without adequate faith, on the surface of the water. The ice was so transparent that I could see through it the beautifully wave-rippled, sandy bottom, and the scales of mica glinting back the down-pouring light. When I knelt down with my face close to the ice, through which the sunbeams were pouring, I was delighted to discover myriads of Tyndall's six-rayed water flowers, magnificently colored.

      A grand old mountain mansion is this Tenaya region! In the glacier period it was a mer de glace, far grander than the mer de glace of Switzerland, which is only about half a mile broad. The Tenaya mer de glace was not less than two miles broad, late in the glacier epoch, when all the principal dividing crests were bare; and its depth was not less than fifteen hundred feet. Ice streams from Mounts Lyell and Dana, and all the mountains between, and from the nearer Cathedral Peak, flowed hither, welded into one, and worked together. After eroding this Tanaya Lake basin, and all the splendidly sculptured rocks and mountains that surround and adorn it, and the great Tenaya Canyon, with its wealth of all that makes mountains sublime, they were welded with the vast South, Lyell, and Illilouette glaciers on one side, and with those of Hoffman on the other—thus forming a portion of a yet grander mer de glace in Yosemite Valley.

      I reached the Tenaya Canyon, on my way home, by coming in from the northeast, rambling down over the shoulders of Mount Watkins, touching bottom a mile above Mirror Lake. From thence home was but a saunter in the moonlight.

      After resting one day, and the weather continuing calm, I ran up over the left shoulder of South Dome and down in front of its grand split face to make some measurements, completed my work, climbed to the right shoulder, struck off along the ridge for Cloud's Rest, and reached the topmost heave of her sunny wave in ample time to see the sunset.

      Cloud's Rest is a thousand feet higher than Tissiack. It is a wavelike crest upon a ridge, which begins at Yosemite with Tissiack, and runs continuously eastward to the thicket of peaks and crests around Lake Tenaya. This lofty granite wall is bent this way and that by the restless and weariless action of glaciers just as if it had been made of dough. But the grand circumference of mountains and forests are coming from far and near, densing into one close assemblage; for the sun, their god and father, with love ineffable, is glowing a sunset farewell. Not one of all the assembled rocks or trees seemed remote. How impressively their faces shone with responsive love!

      I ran home in the moonlight with firm strides; for the sun-love made me strong. Down through the junipers; down through the firs; now in jet shadows, now in white light; over sandy moraines and bare, clanking rocks; past the huge ghost of South Dome rising weird through the firs; past the glorious fall of Nevada, the groves of Illilouette; through the pines of the valley; beneath the bright crystal sky blazing with stars. All of this mountain wealth in one day!—one of the rich ripe days that enlarge one's life; so much of the sun upon one side of it, so much of the moon and stars on the other.

      III. Summer Days at Mount Shasta

       Table of Contents

      Mount Shasta rises in solitary grandeur from the edge of a comparatively low and lightly sculptured lava plain near the northern extremity of the Sierra, and maintains a far more impressive and commanding individuality than any other mountain within the limits of California. Go where you may, within a radius of from fifty to a hundred miles or more, there stands before you the colossal cone of Shasta, clad in ice and snow, the one grand unmistakable landmark—the pole star of the landscape. Far to the southward Mount Whitney lifts its granite summit four or five hundred feet higher than Shasta, but it is nearly snowless during the late summer, and is so feebly individualized that the traveler may search for it in vain among the many rival peaks crowded along the axis of the range to north and south of it, which all alike are crumbling residual masses brought into relief in the degradation of the general mass of the range. The highest point on Mount Shasta, as determined by the State Geological Survey, is 14,440 feet above mean tide. That of Whitney, computed from fewer observations, is about 14,900 feet. But inasmuch as the average elevation of the plain out of which Shasta rises is only about four thousand feet above the sea, while the actual base of the peak of Mount Whitney lies at an elevation of eleven thousand feet, the individual height of the former is about two and a half times as great as that of the latter.

      Approaching Shasta from the south, one obtains glimpses of its snowy cone here and there through the trees from the tops of hills and ridges; but it is not until Strawberry Valley is reached, where there is a grand out-opening of the forests, that Shasta is seen in all its glory. From base to crown clearly revealed with its wealth of woods and waters and fountain snow, rejoicing in the bright mountain sky, and radiating beauty on all the subject landscape like a sun. Standing in a fringing thicket of purple spiraea in the immediate foreground is a smooth expanse of green meadow with its meandering stream, one of the smaller affluents of the Sacramento; then a zone of dark, close forest, its countless spires of pine and fir rising above one another on the swelling base of the mountain in glorious array; and, over all, the great white cone sweeping far into the thin, keen sky—meadow, forest, and grand icy summit harmoniously blending and making one sublime picture evenly balanced.

      The main lines of the landscape are immensely bold and simple, and so regular that it needs all its shaggy wealth of woods and chaparral and its finely tinted ice and snow and brown jutting crags to keep it from looking conventional. In general views of the mountain three distinct zones may be readily defined. The first, which may be called the Chaparral Zone, extends around the base in a magnificent sweep nearly a hundred miles in length on its lower edge, and with a breadth of about seven miles. It is a dense growth of chaparral from three to six or eight feet high, composed chiefly of manzanita, cherry, chincapin, and several species of ceanothus, called deerbrush by the hunters, forming, when in full bloom, one of the most glorious flowerbeds conceivable. The continuity of this flowery zone is interrupted here and there, especially on the south side of the mountain, by wide swaths of coniferous trees, chiefly the sugar and yellow pines, Douglas spruce, silver fir, and incense cedar, many specimens of which are two hundred feet high and five to seven feet in diameter. Goldenrods, asters, gilias, lilies, and lupines, with many other less conspicuous plants, occur in warm sheltered openings in these lower woods, making charming gardens of wildness where bees and butterflies are at home and many a shy bird and squirrel.

      The next higher is the Fir Zone, made up almost exclusively of two species of silver fir. It is from two to three miles wide, has an average elevation above the sea of some six thousand feet on its lower edge and eight thousand on its upper, and is the most regular and best defined of the three.

      The Alpine Zone has a rugged, straggling growth of storm-beaten dwarf pines (Pinus albicaulis), which forms the upper edge of the timberline. This species reaches an elevation of about nine thousand feet, but at this height the tops of the trees rise only a few feet into the thin frosty air, and are closely pressed and shorn by wind and snow; yet they hold on bravely and put forth an abundance of beautiful purple flowers and produce cones and seeds. Down towards the edge of the fir belt they stand erect, forming small, well-formed trunks, and are associated with the taller two-leafed and mountain pines and the beautiful Williamson spruce. Bryanthus, a beautiful flowering heathwort, flourishes a few hundred feet above the timberline, accompanied with kalmia and spiraea. Lichens enliven the faces of the cliffs with their bright colors, and in some of the warmer nooks of the rocks, up to a height of eleven thousand feet, there are a few tufts of dwarf daisies, wallflowers, and penstemons; but, notwithstanding these bloom freely, they make no appreciable show at a distance, and the stretches of rough brown lava beyond the storm-beaten trees seem as bare of vegetation as the great snow fields and glaciers of the summit.

      Shasta is a fire-mountain, an old volcano gradually accumulated and built up into the blue deep of the sky by successive eruptions of ashes and molten lava which, shot high in the air and falling in darkening showers, and flowing from chasms and craters, grew outward and upward like the trunk of a knotty, bulging tree. Not in one grand convulsion was Shasta given birth, nor in any one special period of volcanic storm and stress, though mountains more than a thousand feet in height have been cast up like molehills in a night—quick contributions to the wealth of the landscapes,
