Yonder stands the South Dome, its crown high above our camp, though its base is four thousand feet below us; a most noble rock, it seems full of thought, clothed with living light, no sense of dead stone about it, all spiritualized, neither heavy looking nor light, steadfast in serene strength like a god.
The woodchuck (Arctomys monax) of the bleak mountain-tops is a very different sort of mountaineer—the most bovine of rodents, a heavy eater, fat, aldermanic in bulk and fairly bloated, in his high pastures, like a cow in a clover field. One woodchuck would outweigh a[Pg 173] hundred chipmunks, and yet he is by no means a dull animal. In the midst of what we regard as storm-beaten desolation he pipes and whistles right cheerily, and enjoys long life in his skyland homes. His burrow is made in disintegrated rocks or beneath large boulders. Coming out of his den in the cold hoarfrost mornings, he takes a sun-bath on some favorite flat-topped rock, then goes to breakfast in garden hollows, eats grass and flowers until comfortably swollen, then goes a-visiting to fight and play. How long a woodchuck lives in this bracing air I don’t know, but some of them are rusty and gray like lichen-covered boulders.

A good many herbaceous plants come thus far up the mountains from the plains, and are now in flower, two months later than their low[Pg 40]land relatives. Saw a few columbines to-day. Most of the ferns are in their prime,—rock ferns on the sunny hillsides, cheilanthes, pellæa, gymnogramme; woodwardia, aspidium, woodsia along the stream banks, and the common Pteris aquilina on sandy flats. This last, however common, is here making shows of strong, exuberant, abounding beauty to set the botanist wild with admiration. I measured some scarce full grown that are more than seven feet high. Though the commonest and most widely distributed of all the ferns, I might almost say that I never saw it before. The broad-shouldered fronds held high on smooth stout stalks growing close together, overleaning and overlapping, make a complete ceiling, beneath which one may walk erect over several acres without being seen, as if beneath a roof. And how soft and lovely the light streaming through this living ceiling, revealing the arching branching ribs and veins of the fronds as the framework of countless panes of pale green and yellow plant-glass nicely fitted together—a fairyland created out of the commonest fern-stuff.
In the great Central Valley of California there are only two seasons—spring and summer. The spring begins with the first rainstorm, which usually falls in November. In a few months the wonderful flowery vegetation is in full bloom, and by the end of May it is dead and dry and crisp, as if every plant had been roasted in an oven.June 14. The pool-basins below the falls and cascades hereabouts, formed by the heavy down-plunging currents, are kept nicely clean and clear of detritus. The heavier parts of the material swept over the falls are heaped up a short distance in front of the basins in the form of a dam, thus tending, together with erosion, to increase their size. Sudden changes, however, are effected during the spring floods, when the snow is melting and the upper tributaries are roaring loud from “bank to brae.” Then boulders that have fallen into the channels, and which the ordinary summer and winter currents were unable to move, are suddenly swept forward as by a mighty besom, hurled over the falls into these pools, and piled up in a new dam together with part of the old one, while some of the smaller boulders are carried further down stream and variously lodged according to size and shape, all seeking rest where the force of the current is less than the resistance they are able to offer. But the greatest changes made in these relations of fall, pool,[Pg 48] and dam are caused, not by the ordinary spring floods, but by extraordinary ones that occur at irregular intervals. The testimony of trees growing on flood boulder deposits shows that a century or more has passed since the last master flood came to awaken everything movable to go swirling and dancing on wonderful journeys. These floods may occur during the summer, when heavy thunder-showers, called “cloud-bursts,” fall on wide, steeply inclined stream basins furrowed by converging channels, which suddenly gather the waters together into the main trunk in booming torrents of enormous transporting power, though short lived.
We are camped near the Soda Springs on the north side of the river. A hard time we had getting the sheep across. They were driven into a horseshoe bend and fairly crowded off the bank. They seemed willing to suffer death rather than risk getting wet, though they swim well enough when they have to. Why sheep should be so unreasonably afraid of water, I don’t know, but they do fear it as soon as they are born and perhaps before. I once saw a lamb only a few hours old approach a shallow stream about two feet wide and an inch deep, after it had walked only about a hundred yards on its life journey. All the flock to which it belonged had crossed this inch-deep stream, and as the mother and her lamb were the last to cross, I had a good opportunity to observe them. As soon as the flock was out of the way, the anxious mother crossed over and called the youngster. It walked cautiously to the brink, gazed at the water, bleated piteously, and refused to venture. The patient mother went back to it again and again to encourage it, but long without avail. Like the pilgrim on Jordan’s stormy bank it feared to launch away. At length,[Pg 202] gathering its trembling inexperienced legs for the mighty effort, throwing up its head as if it knew all about drowning, and was anxious to keep its nose above water, it made the tremendous leap, and landed in the middle of the inch-deep stream. It seemed astonished to find that, instead of sinking over head and ears, only its toes were wet, gazed at the shining water a few seconds, and then sprang to the shore safe and dry through the dreadful adventure. All kinds of wild sheep are mountain animals, and their descendants’ dread of water is not easily accounted for.
We are now about seven thousand feet above the sea, and the nights are so cool we have to pile coats and extra clothing on top of our blankets. Tamarack Creek is icy cold, delicious, exhilarating champagne water. It is flowing bank-full in the meadow with silent speed, but only a few hundred yards below our camp the ground is bare gray granite strewn with boulders, large spaces being without a single tree or only a small one here and there anchored in narrow seams and cracks. The boulders, many of them very large, are not in piles or scattered like rubbish among loose crumbling débris as if weathered out of the solid as boulders of disintegration; they mostly occur singly, and are lying on a clean pavement on which the sunshine falls in a glare that contrasts with the shimmer of light and shade we have been accustomed to in the leafy woods.[Pg 101] And, strange to say, these boulders lying so still and deserted, with no moving force near them, no boulder carrier anywhere in sight, were nevertheless brought from a distance, as difference in color and composition shows, quarried and carried and laid down here each in its place; nor have they stirred, most of them, through calm and storm since first they arrived. They look lonely here, strangers in a strange land,—huge blocks, angular mountain chips, the largest twenty or thirty feet in diameter, the chips that Nature has made in modeling her landscapes, fashioning the forms of her mountains and valleys. And with what tool were they quarried and carried? On the pavement we find its marks. The most resisting unweathered portion of the surface is scored and striated in a rigidly parallel way, indicating that the region has been overswept by a glacier from the northeastward, grinding down the general mass of the mountains, scoring and polishing, producing a strange, raw, wiped appearance, and dropping whatever boulders it chanced to be carrying at the time it was melted at the close of the Glacial Period. A fine discovery this. As for the forests we have been passing through, they are probably growing on deposits of soil most of which has been laid down by this same ice agent in the[Pg 102] form of moraines of different sorts, now in great part disintegrated and outspread by post-glacial weathering.
