Had we been here to look during the glacial period we would have found a wrinkled ocean of ice continuous as that now covering North Greenland and the lands about the South Pole, filling every valley and canyon, flowing deep above every ridge, leaving only the tops of the peaks rising darkly above the rock-encumbered waves, like foam-streaked islets in the midst of a stormy sea--these islets the only hints of the glorious landscapes now lying warm and fruitful beneath the sun. Now all the work of creation seems done. In the deep, brooding silence all appears motionless. But in the midst of this outer steadfastness we know there is incessant motion. Ever and anon avalanches are falling from yonder peaks. These cliff-bound glaciers seemingly wedged fast and immovable, are flowing like water and grinding the rocks beneath them. The lakes are lapping their granite shores, and wearing them away, and every one of these young rivers is fretting the air into music, and carrying the mountains to the plains. Here are the roots of the life of the lowlands with all their wealth of vineyard and grove, and here more simply than elsewhere is the eternal flux of nature manifested.
But in the thick of these fine lessons you must remember that the sun is wheeling far to the west, and you have many a weary and nerve-trying step to make ere you can reach the timber-line where you may lie warm through the night. But with keen caution and instinct and the guidance of your guardian angel you may pass every danger in safety, and in another delightful day win your way back again to your camp to rest on the beautiful Tuolumne River.
II. The Passes of the High Sierra
The roads that Nature has opened through the heart of the High Sierra are hard to travel. So the sedate plodder of the lowlands would say, whether accustomed to trace the level furrows of fields, or the paved streets of cities. But as people oftentimes build better than they know, so also do they walk and climb and wander better than they know, and so it comes, that urged onward by a mysterious love of wild beauty and adventure, we find ourselves far from the beaten ways of life, toiling through these rugged mountain passes without thinking of a reason for embracing with such ungovernable enthusiasm so much stem privation and hardship.
"Try not the pass" may sound in our ears, but despite the solemn warning, come from whom it may, the passes will be tried until the end of time, in the face of every danger of rock, avalanche, and blinding storm. And whatever the immediate motive may be that starts us on our travels--wild landscapes, or adventures, or mere love of gain, the passes themselves will in the end be found better than anything to which they directly lead; calling every faculty into vigorous action, rousing from soul-wasting apathy and ease, and opening windows into the best regions of both earth and heaven.
The glaciers were the pass makers of the Sierra, and by them the ways of all mountaineers have been determined. A short geological time before the coming on of that winter of winters, called "The Glacial Period," a vast deluge of molten rocks poured from many a chasm and crater on the flanks and summit of the range, obliterating every distinction of peak and pass throughout its northern portions, filling the lake basins, flooding ridge and valley alike, and effacing nearly every feature of the pre-glacial landscapes.
Then, after these all-destroying fire-floods ceased to flow, but while the great volcanic cones built up along the axis of the range, still burned and smoked, the whole Sierra passed under the domain of ice and snow. Over the bald, featureless, fire-blackened mountains glaciers crawled, covering them all from summit to base with a mantle of ice; and thus with infinite deliberation the work was begun of sculpturing the range anew. Those mighty agents of erosion, halting never through unnumbered centuries, ground and crushed the flinty lavas and granites beneath their crystal folds. Particle by particle, chip by chip, block by block the work went on, wasting and building, until in the fullness of time the mountains were born again, the passes and the summits between them, ridges and canyons, and all the main features of the range coming to the light nearly as we behold them today.
Looking into the passes near the summits, they seem singularly gloomy and bare, like raw quarries of dead, unfertilized stone--gashes in the cold rock-bones of the mountains above the region of life, empty as when they first emerged from beneath the folds of the ice-mantle. Faint indeed are the marks of any kind of life, and at first sight they may not be seen at all. Nevertheless birds sing and flowers bloom in the highest of them all, and in no part of the range, north or south, is there any break in the chain of life, however much it may be wasted and turned aside by snow and ice, and flawless granite.
Compared with the well-known passes of Switzerland, those of the south half of the Sierra are somewhat higher, but they contain less ice and snow, and enjoy a better summer climate, making them, upon the whole, more open and approachable. A carriage-road has been constructed through the Sonora Pass, the summit of which is 10,150 feet above the level of the sea--878 feet higher than the highest carriage-pass in Switzerland--the Stelvio Pass.
In a distance of 140 miles between lat. 36° degrees 20' and 38° degrees the lowest pass I have yet discovered exceeds 9,000 feet, and the average height of all above sea-level is perhaps not far from 11,000 feet.
Substantial carriage-roads lead through the Carson and Johnson Passes near the head of Lake Tahoe, over which immense quantities of freight were hauled from California to the mining regions of Nevada prior to the construction of the Central Pacific Railroad through the Donner Pass. Miles of mules and ponderous wagons might then be seen slowly crawling beneath a cloud of dust through the majestic forest aisles, the drivers shouting in every language, and making a din and disorder strangely out of keeping with the solemn grandeur of the mountains about them.
To the northward of the memorable Donner Pass, 7,056 feet in height, a number of lower passes occur, through whose rugged defiles long emigrant trains, with footsore cattle and sun-cracked wagons a hundred times mended, wearily toiled during the early years of the Gold Period. Coming from far, through a thousand dangers, making a way over trackless wastes, the snowy Sierra at length loomed in sight, to them the eastern wall of the Land of Gold. And as they gazed through the tremulous haze of the desert, with what joy must they have descried the gateway through which they were so soon to pass to the better land of all their golden hopes and dreams!
Between the Sonora Pass and the southern extremity of the High Sierra, a distance of a 160 miles, there is not a single carriage-road conducting from one side of the range to the other, and only five passes with trails of the roughest description. These are barely practicable for animals, a pass in this region meaning simply any notch with its connecting canyon and ridges through which one may, by the exercise of unlimited patience, make out to lead a surefooted mule or mustang, one that can not only step well among loose stones, but also jump well down rugged stairways, and slide with limbs firmly braced down smooth inclines of rock and snow.
Only three of the five may be said to be in use--the Kearsarge, Mono, and Virginia Creek passes--the tracks leading through the others being only obscure Indian trails not graded in the least, and scarce at all traceable by white men. Much of the way lies over solid pavements where the unshod ponies of the Indians leave no appreciable sign, and across loose taluses where only a slight displacement is visible here and there, and through thickets of weeds and bushes, leaving
