wormwood. The Bannacks, on the contrary, were encamped among fine springs of water, where there was grass in abundance. Some of these springs gush out of the earth in sufficient quantity to turn a mill; and furnish beautiful streams, clear as crystal, and full of trout of a large size, which may be seen darting about the transparent water.
Winter now set in regularly. The snow had fallen frequently, and in large quantities, and covered the ground to a depth of a foot; and the continued coldness of the weather prevented any thaw.
By degrees, a distrust which at first subsisted between the Indians and the trappers, subsided, and gave way to mutual confidence and good will. A few presents convinced the chiefs that the white men were their friends; nor were the white men wanting in proofs of the honesty and good faith of their savage neighbors. Occasionally, the deep snow and the want of fodder obliged them to turn their weakest horses out to roam in quest of sustenance. If they at any time strayed to the camp of the Bannacks, they were immediately brought back. It must be confessed, however, that if the stray horse happened, by any chance, to be in vigorous plight and good condition, though he was equally sure to be returned by the honest Bannacks, yet it was always after the lapse of several days, and in a very gaunt and jaded state; and always with the remark that they had found him a long way off. The uncharitable were apt to surmise that he had, in the interim, been well used up in a buffalo hunt; but those accustomed to Indian morality in the matter of horseflesh, considered it a singular evidence of honesty that he should be brought back at all.
Being convinced, therefore, from these, and other circumstances, that his people were encamped in the neighborhood of a tribe as honest as they were valiant, and satisfied that they would pass their winter unmolested, Captain Bonneville prepared for a reconnoitring expedition of great extent and peril. This was, to penetrate to the Hudson’s Bay establishments on the banks of the Columbia, and to make himself acquainted with the country and the Indian tribes; it being one part of his scheme to establish a trading post somewhere on the lower part of the river, so as to participate in the trade lost to the United States by the capture of Astoria. This expedition would, of course, take him through the Snake River country, and across the Blue Mountains, the scenes of so much hardship and disaster to Hunt and Crooks, and their Astorian bands, who first explored it, and he would have to pass through it in the same frightful season, the depth of winter.
The idea of risk and hardship, however, only served to stimulate the adventurous spirit of the captain. He chose three companions for his journey, put up a small stock of necessaries in the most portable form, and selected five horses and mules for themselves and their baggage. He proposed to rejoin his band in the early part of March, at the winter encampment near the Portneuf. All these arrangements being completed, he mounted his horse on Christmas morning, and set off with his three comrades. They halted a little beyond the Bannack camp, and made their Christmas dinner, which, if not a very merry, was a very hearty one, after which they resumed their journey.
They were obliged to travel slowly, to spare their horses; for the snow had increased in depth to eighteen inches; and though somewhat packed and frozen, was not sufficiently so to yield firm footing. Their route lay to the west, down along the left side of Snake River; and they were several days in reaching the first, or American Falls. The banks of the river, for a considerable distance, both above and below the falls, have a volcanic character: masses of basaltic rock are piled one upon another; the water makes its way through their broken chasms, boiling through narrow channels, or pitching in beautiful cascades over ridges of basaltic columns.
Beyond these falls, they came to a picturesque, but inconsiderable stream, called the Cassie. It runs through a level valley, about four miles wide, where the soil is good; but the prevalent coldness and dryness of the climate is unfavorable to vegetation. Near to this stream there is a small mountain of mica slate, including garnets. Granite, in small blocks, is likewise seen in this neighborhood, and white sandstone. From this river, the travellers had a prospect of the snowy heights of the Salmon River Mountains to the north; the nearest, at least fifty miles distant.
In pursuing his course westward, Captain Bonneville generally kept several miles from Snake River, crossing the heads of its tributary streams; though he often found the open country so encumbered by volcanic rocks, as to render travelling extremely difficult. Whenever he approached Snake River, he found it running through a broad chasm, with steep, perpendicular sides of basaltic rock. After several days’ travel across a level plain, he came to a part of the river which filled him with astonishment and admiration. As far as the eye could reach, the river was walled in by perpendicular cliffs two hundred and fifty feet high, beetling like dark and gloomy battlements, while blocks and fragments lay in masses at their feet, in the midst of the boiling and whirling current. Just above, the whole stream pitched in one cascade above forty feet in height, with a thundering sound, casting up a volume of spray that hung in the air like a silver mist. These are called by some the Fishing Falls, as the salmon are taken here in immense quantities. They cannot get by these falls.
After encamping at this place all night, Captain Bonneville, at sunrise, descended with his party through a narrow ravine, or rather crevice, in the vast wall of basaltic rock which bordered the river; this being the only mode, for many miles, of getting to the margin of the stream.
The snow lay in a thin crust along the banks of the river, so that their travelling was much more easy than it had been hitherto. There were foot tracks, also, made by the natives, which greatly facilitated their progress. Occasionally, they met the inhabitants of this wild region; a timid race, and but scantily provided with the necessaries of life. Their dress consisted of a mantle about four feet square, formed of strips of rabbit skins sewed together; this they hung over their shoulders, in the ordinary Indian mode of wearing the blanket. Their weapons were bows and arrows; the latter tipped with obsidian, which abounds in the neighborhood. Their huts were shaped like haystacks, and constructed of branches of willow covered with long grass, so as to be warm and comfortable. Occasionally, they were surrounded by small inclosures of wormwood, about three feet high, which gave them a cottage-like appearance. Three or four of these tenements were occasionally grouped together in some wild and striking situation, and had a picturesque effect. Sometimes they were in sufficient number to form a small hamlet. From these people, Captain Bonneville’s party frequently purchased salmon, dried in an admirable manner, as were likewise the roes. This seemed to be their prime article of food; but they were extremely anxious to get buffalo meat in exchange.
The high walls and rocks, within which the travellers had been so long inclosed, now occasionally presented openings, through which they were enabled to ascend to the plain, and to cut off considerable bends of the river.
Throughout the whole extent of this vast and singular chasm, the scenery of the river is said to be of the most wild and romantic character. The rocks present every variety of masses and grouping. Numerous small streams come rushing and boiling through narrow clefts and ravines: one of a considerable size issued from the face of a precipice, within twenty-five feet of its summit; and after running in nearly a horizontal line for about one hundred feet, fell, by numerous small cascades, to the rocky bank of the river.
In its career through this vast and singular defile, Snake River is upward of three hundred yards wide, and as clear as spring water. Sometimes it steals along with a tranquil and noiseless course; at other times, for miles and miles, it dashes on in a thousand rapids, wild and beautiful to the eye, and lulling the ear with the soft tumult of plashing waters.
Many of the tributary streams of Snake River, rival it in the wildness and picturesqueness of their scenery. That called the Bruneau; is particularly cited. It runs through a tremendous chasm, rather than a valley, extending upwards of a hundred and fifty miles. You come upon it on a sudden, in traversing a level plain. It seems as if you could throw a stone across from cliff to cliff; yet, the valley is near two thousand feet deep: so that the river looks like an inconsiderable stream. Basaltic rocks rise perpendicularly, so that it is impossible to get from the plain to the water, or from the river margin to the plain. The current is bright and limpid. Hot springs are found on the borders of this river. One bursts out of the cliffs forty feet above the river, in a stream sufficient to turn a mill, and sends up a cloud of vapor.
