To the southwest, the eye ranged over an immense extent of wilderness, with what appeared to be a snowy vapor resting upon its horizon. This, however, was pointed out as another branch of the Great Chippewyan, or Rocky chain; being the Eutaw Mountains, at whose basis the wandering tribe of hunters of the same name pitch their tents. We can imagine the enthusiasm of the worthy captain when he beheld the vast and mountainous scene of his adventurous enterprise thus suddenly unveiled before him. We can imagine with what feelings of awe and admiration he must have contemplated the Wind River Sierra, or bed of mountains; that great fountainhead from whose springs, and lakes, and melted snows some of those mighty rivers take their rise, which wander over hundreds of miles of varied country and clime, and find their way to the opposite waves of the Atlantic and the Pacific.
The Wind River Mountains are, in fact, among the most remarkable of the whole Rocky chain; and would appear to be among the loftiest. They form, as it were, a great bed of mountains, about eighty miles in length, and from twenty to thirty in breadth; with rugged peaks, covered with eternal snows, and deep, narrow valleys full of springs, and brooks, and rock-bound lakes. From this great treasury of waters issue forth limpid streams, which, augmenting as they descend, become main tributaries of the Missouri on the one side, and the Columbia on the other; and give rise to the Seeds-ke-dee Agie, or Green River, the great Colorado of the West, that empties its current into the Gulf of California.
The Wind River Mountains are notorious in hunters’ and trappers’ stories: their rugged defiles, and the rough tracts about their neighborhood, having been lurking places for the predatory hordes of the mountains, and scenes of rough encounter with Crows and Blackfeet. It was to the west of these mountains, in the valley of the Seeds-ke-dee Agie, or Green River, that Captain Bonneville intended to make a halt for the purpose of giving repose to his people and his horses after their weary journeying; and of collecting information as to his future course. This Green River valley, and its immediate neighborhood, as we have already observed, formed the main point of rendezvous, for the present year, of the rival fur companies, and the motley populace, civilized and savage, connected with them. Several days of rugged travel, however, yet remained for the captain and his men before they should encamp in this desired resting-place.
On the 21st of July, as they were pursuing their course through one of the meadows of the Sweet Water, they beheld a horse grazing at a little distance. He showed no alarm at their approach, but suffered himself quietly to be taken, evincing a perfect state of tameness. The scouts of the party were instantly on the look-out for the owners of this animal; lest some dangerous band of savages might be lurking in the vicinity. After a narrow search, they discovered the trail of an Indian party, which had evidently passed through that neighborhood but recently. The horse was accordingly taken possession of, as an estray; but a more vigilant watch than usual was kept round the camp at nights, lest his former owners should be upon the prowl.
The travellers had now attained so high an elevation that on the 23d of July, at daybreak, there was considerable ice in the waterbuckets, and the thermometer stood at twenty-two degrees. The rarefy of the atmosphere continued to affect the wood-work of the wagons, and the wheels were incessantly falling to pieces. A remedy was at length devised. The tire of each wheel was taken off; a band of wood was nailed round the exterior of the felloes, the tire was then made red hot, replaced round the wheel, and suddenly cooled with water. By this means, the whole was bound together with great compactness.
The extreme elevation of these great steppes, which range along the feet of the Rocky Mountains, takes away from the seeming height of their peaks, which yield to few in the known world in point of altitude above the level of the sea.
On the 24th, the travellers took final leave of the Sweet Water, and keeping westwardly, over a low and very rocky ridge, one of the most southern spurs of the Wind River Mountains, they encamped, after a march of seven hours and a half, on the banks of a small clear stream, running to the south, in which they caught a number of fine trout.
The sight of these fish was hailed with pleasure, as a sign that they had reached the waters which flow into the Pacific; for it is only on the western streams of the Rocky Mountains that trout are to be taken. The stream on which they had thus encamped proved, in effect, to be tributary to the Seeds-ke-dee Agie, or Green River, into which it flowed at some distance to the south.
Captain Bonneville now considered himself as having fairly passed the crest of the Rocky Mountains; and felt some degree of exultation in being the first individual that had crossed, north of the settled provinces of Mexico, from the waters of the Atlantic to those of the Pacific, with wagons. Mr. William Sublette, the enterprising leader of the Rocky Mountain Fur Company, had, two or three years previously, reached the valley of the Wind River, which lies on the northeast of the mountains; but had proceeded with them no further.
A vast valley now spread itself before the travellers, bounded on one side by the Wind River Mountains, and to the west, by a long range of high hills. This, Captain Bonneville was assured by a veteran hunter in his company, was the great valley of the Seedske-dee; and the same informant would have fain persuaded him that a small stream, three feet deep, which he came to on the 25th, was that river. The captain was convinced, however, that the stream was too insignificant to drain so wide a valley and the adjacent mountains: he encamped, therefore, at an early hour, on its borders, that he might take the whole of the next day to reach the main river; which he presumed to flow between him and the distant range of western hills.
On the 26th of July, he commenced his march at an early hour, making directly across the valley, toward the hills in the west; proceeding at as brisk a rate as the jaded condition of his horses would permit. About eleven o’clock in the morning, a great cloud of dust was descried in the rear, advancing directly on the trail of the party. The alarm was given; they all came to a halt, and held a council of war. Some conjectured that the band of Indians, whose trail they had discovered in the neighborhood of the stray horse, had been lying in wait for them in some secret fastness of the mountains; and were about to attack them on the open plain, where they would have no shelter. Preparations were immediately made for defence; and a scouting party sent off to reconnoitre. They soon came galloping back, making signals that all was well. The cloud of dust was made by a band of fifty or sixty mounted trappers, belonging to the American Fur Company, who soon came up, leading their pack-horses. They were headed by Mr. Fontenelle, an experienced leader, or “partisan,” as a chief of a party is called in the technical language of the trappers.
Mr. Fontenelle informed Captain Bonneville that he was on his way from the company’s trading post on the Yellowstone to the yearly rendezvous, with reinforcements and supplies for their hunting and trading parties beyond the mountains; and that he expected to meet, by appointment, with a band of free trappers in that very neighborhood. He had fallen upon the trail of Captain Bonneville’s party, just after leaving the Nebraska; and, finding that they had frightened off all the game, had been obliged to push on, by forced marches, to avoid famine: both men and horses were, therefore, much travel-worn; but this was no place to halt; the plain before them he said was destitute of grass and water, neither of which would be met with short of the Green River, which was yet at a considerable distance. He hoped, he added, as his party were all on horseback, to reach the river, with hard travelling, by nightfall: but he doubted the possibility of Captain Bonneville’s arrival there with his wagons before the day following. Having imparted this information, he pushed forward with all speed.
Captain Bonneville followed on as fast as circumstances would permit. The ground was firm and gravelly; but the horses were too much fatigued to move rapidly. After a long and harassing day’s march, without pausing for a noontide meal, they were compelled, at nine o’clock at night, to encamp in an open plain, destitute of water or pasturage. On the following morning, the horses were turned loose at the peep of day; to slake their thirst, if possible, from the dew collected on the sparse grass, here and there springing up among dry sand-banks. The soil of a great part of this Green River valley is a whitish clay, into which
