of the Immahah Valley — The exhausted traveller
THE TEMPERATURE of the regions west of the Rocky Mountains is much milder than in the same latitudes on the Atlantic side; the upper plains, however, which lie at a distance from the seacoast, are subject in winter to considerable vicissitude; being traversed by lofty “sierras,” crowned with perpetual snow, which often produce flaws and streaks of intense cold This was experienced by Captain Bonneville and his companions in their progress westward. At the time when they left the Bannacks Snake River was frozen hard: as they proceeded, the ice became broken and floating; it gradually disappeared, and the weather became warm and pleasant, as they approached a tributary stream called the Little Wyer; and the soil, which was generally of a watery clay, with occasional intervals of sand, was soft to the tread of the horses. After a time, however, the mountains approached and flanked the river; the snow lay deep in the valleys, and the current was once more icebound.
Here they were visited by a party of Root Diggers, who were apparently rising in the world, for they had “horse to ride and weapon to wear,” and were altogether better clad and equipped than any of the tribe that Captain Bonneville had met with. They were just from the plain of Boisee River, where they had left a number of their tribe, all as well provided as themselves; having guns, horses, and comfortable clothing. All these they obtained from the Lower Nez Perces, with whom they were in habits [sic] of frequent traffic. They appeared to have imbibed from that tribe their non-combative principles, being mild and inoffensive in their manners. Like them, also, they had something of religious feelings; for Captain Bonneville observed that, before eating, they washed their hands, and made a short prayer; which he understood was their invariable custom. From these Indians, he obtained a considerable supply of fish, and an excellent and well-conditioned horse, to replace one which had become too weak for the journey.
The travellers now moved forward with renovated spirits; the snow, it is true, lay deeper and deeper as they advanced, but they trudged on merrily, considering themselves well provided for the journey, which could not be of much longer duration.
They had intended to proceed up the banks of Gun Creek, a stream which flows into Snake River from the west; but were assured by the natives that the route in that direction was impracticable. The latter advised them to keep along Snake River, where they would not be impeded by the snow. Taking one of the Diggers for a guide, they set off along the river, and to their joy soon found the country free from snow, as had been predicted, so that their horses once more had the benefit of tolerable pasturage. Their Digger proved an excellent guide, trudging cheerily in the advance. He made an unsuccessful shot or two at a deer and a beaver; but at night found a rabbit hole, whence he extracted the occupant, upon which, with the addition of a fish given him by the travellers, he made a hearty supper, and retired to rest, filled with good cheer and good humor.
The next day the travellers came to where the hills closed upon the river, leaving here and there intervals of undulating meadow land. The river was sheeted with ice, broken into hills at long intervals. The Digger kept on ahead of the party, crossing and recrossing the river in pursuit of game, until, unluckily, encountering a brother Digger, he stole off with him, without the ceremony of leave-taking.
Being now left to themselves, they proceeded until they came to some Indian huts, the inhabitants of which spoke a language totally different from any they had yet heard. One, however, understood the Nez Perce language, and through him they made inquiries as to their route. These Indians were extremely kind and honest, and furnished them with a small quantity of meat; but none of them could be induced to act as guides.
Immediately in the route of the travellers lay a high mountain, which they ascended with some difficulty. The prospect from the summit was grand but disheartening. Directly before them towered the loftiest peaks of Immahah, rising far higher than the elevated ground on which they stood: on the other hand, they were enabled to scan the course of the river, dashing along through deep chasms, between rocks and precipices, until lost in a distant wilderness of mountains, which closed the savage landscape.
They remained for a long time contemplating, with perplexed and anxious eye, this wild congregation of mountain barriers, and seeking to discover some practicable passage. The approach of evening obliged them to give up the task, and to seek some camping ground for the night. Moving briskly forward, and plunging and tossing through a succession of deep snow-drifts, they at length reached a valley known among trappers as the “Grand Rond,” which they found entirely free from snow.
This is a beautiful and very fertile valley, about twenty miles long and five or six broad; a bright cold stream called the Fourche de Glace, or Ice River, runs through it. Its sheltered situation, embosomed in mountains, renders it good pasturaging ground in the winter time; when the elk come down to it in great numbers, driven out of the mountains by the snow. The Indians then resort to it to hunt. They likewise come to it in the summer time to dig the camash root, of which it produces immense quantities. When this plant is in blossom, the whole valley is tinted by its blue flowers, and looks like the ocean when overcast by a cloud.
After passing a night in this valley, the travellers in the morning scaled the neighboring hills, to look out for a more eligible route than that upon which they had unluckily fallen; and, after much reconnoitring, determined to make their way once more to 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
