The Adventures of Captain Bonneville, U. S. A., in the Rocky Mountains and the Far West

the river, and to travel upon the ice when the banks should prove impassable.
    On the second day after this determination, they were again upon Snake River, but, contrary to their expectations, it was nearly free from ice. A narrow riband ran along the shore, and sometimes there was a kind of bridge across the stream, formed of old ice and snow. For a short time, they jogged along the bank, with tolerable facility, but at length came to where the river forced its way into the heart of the mountains, winding between tremendous walls of basaltic rock, that rose perpendicularly from the water’s edge, frowning in bleak and gloomy grandeur. Here difficulties of all kinds beset their path. The snow was from two to three feet deep, but soft and yielding, so that the horses had no foothold, but kept plunging forward, straining themselves by perpetual efforts. Sometimes the crags and promontories forced them upon the narrow riband of ice that bordered the shore; sometimes they had to scramble over vast masses of rock which had tumbled from the impending precipices; sometimes they had to cross the stream upon the hazardous bridges of ice and snow, sinking to the knee at every step; sometimes they had to scale slippery acclivities, and to pass along narrow cornices, glazed with ice and sleet, a shouldering wall of rock on one side, a yawning precipice on the other, where a single false step would have been fatal. In a lower and less dangerous pass, two of their horses actually fell into the river; one was saved with much difficulty, but the boldness of the shore prevented their rescuing the other, and he was swept away by the rapid current.
    In this way they struggled forward, manfully braving difficulties and dangers, until they came to where the bed of the river was narrowed to a mere chasm, with perpendicular walls of rock that defied all further progress. Turning their faces now to the mountain, they endeavored to cross directly over it; but, after clambering nearly to the summit, found their path closed by insurmountable barriers.
    Nothing now remained but to retrace their steps. To descend a cragged mountain, however, was more difficult and dangerous than to ascend it. They had to lower themselves cautiously and slowly, from steep to steep; and, while they managed with difficulty to maintain their own footing, to aid their horses by holding on firmly to the rope halters, as the poor animals stumbled among slippery rocks, or slid down icy declivities. Thus, after a day of intense cold, and severe and incessant toil, amidst the wildest of scenery, they managed, about nightfall, to reach the camping ground, from which they had started in the morning, and for the first time in the course of their rugged and perilous expedition, felt their hearts quailing under their multiplied hardships.
    A hearty supper, a tranquillizing pipe, and a sound night’s sleep, put them all in better mood, and in the morning they held a consultation as to their future movements. About four miles behind, they had remarked a small ridge of mountains approaching closely to the river. It was determined to scale this ridge, and seek a passage into the valley which must lie beyond. Should they fail in this, but one alternative remained. To kill their horses, dry the flesh for provisions, make boats of the hides, and, in these, commit themselves to the stream—a measure hazardous in the extreme.
    A short march brought them to the foot of the mountain, but its steep and cragged sides almost discouraged hope. The only chance of scaling it was by broken masses of rock, piled one upon another, which formed a succession of crags, reaching nearly to the summit. Up these they wrought their way with indescribable difficulty and peril, in a zigzag course, climbing from rock to rock, and helping their horses up after them; which scrambled among the crags like mountain goats; now and then dislodging some huge stone, which, the moment they had left it, would roll down the mountain, crashing and rebounding with terrific din. It was some time after dark before they reached a kind of platform on the summit of the mountain, where they could venture to encamp. The winds, which swept this naked height, had whirled all the snow into the valley beneath, so that the horses found tolerable winter pasturage on the dry grass which remained exposed. The travellers, though hungry in the extreme, were fain to make a very frugal supper; for they saw their journey was likely to
