From the Mexican frontier up into Oregon, a strip of actual desert lies under the east slope of the great chain, and stretches eastward sometimes as far as five hundred miles, varied by successions of bare, white ground, effervescing under the hot sun with alkaline salts, plains covered by the low, ashy-hued sage-plant, high, barren, rocky ranges, which are folds of metamorphic rocks, and piled-up lavas of bright red or yellow colors; all over-arched by a sky which is at one time of a hot, metallic brilliancy, and again the tenderest of evanescent purple or pearl.
Utterly opposed are the two aspects of the Sierras from these east and west approaches. I remember how stern and strong the chain looked to me when I first saw it from the Colorado desert.
It was in early May, 1866. My companion, Mr. James Terry Gardiner, and I got into the saddle on the bank of the Colorado River, and headed westward over the road from La Paz to San Bernardino. My mount was a tough, magnanimous sort of mule, who at all times did his very best; that of my friend, an animal still hardier, but altogether wanting in moral attributes. He developed a singular antipathy for my mule, and utterly refused to march within a quarter of a mile of me; so that over a wearying route of three hundred miles we were obliged to travel just beyond the reach of a shout. Hour after hour, plodding along at a dog-trot, we pursued our solitary way without the spice of companionship, and altogether deprived of the melodramatic satisfaction of loneliness.
Far ahead of us a white line traced across the barren plain marked our road. It seemed to lead to nowhere, except onward over more and more arid reaches of desert. Rolling hills of crude color and low, gloomy contour rose above the general level. Here and there the eye was arrested by a towering crag, or an elevated, rocky mountain group, whose naked sides sank down into the desert, unrelieved by the shade of a solitary tree. The whole aspect of nature was dull in color, and gloomy with an all-pervading silence of death. Although the summer had not fairly opened, a torrid sun beat down with cruel severity, blinding the eye with its brilliance, and inducing a painful slow fever. The very plants, scorched to a crisp, were ready, at the first blast of a sirocco, to be whirled away and ground to dust. Certain bare zones lay swept clean of the last dry stems across our path, marking the track of whirlwinds. Water was only found at intervals of sixty or seventy miles, and, when reached, was more of an aggravation than a pleasure,--bitter, turbid, and scarce; we rode for it all day, and berated it all night, only to leave it at sunrise with a secret fear that we might fare worse next time.
