At daybreak they were up and on the march, scrambling up the mountain side for the distance of eight painful miles. From the casual hints given in the travelling memoranda of Mr. Stuart, this mountain would seem to offer a rich field of speculation for the geologist. Here was a plain three miles in diameter, strewed with pumice stones and other volcanic reliques, with a lake in the centre, occupying what had probably been the crater. Here were also, in some places, deposits of marine shells, indicating that this mountain crest had at some remote period been below the waves.
After pausing to repose, and to enjoy these grand but savage and awful scenes, they began to descend the eastern side of the mountain. The descent was rugged and romantic, along deep ravines and defiles, overhung with crags and cliffs, among which they beheld numbers of the ahsahta or bighorn, skipping fearlessly from rock to rock. Two of them they succeeded in bringing down with their rifles, as they peered fearlessly from the brow of their airy precipices.
Arrived at the foot of the mountain, the travellers found a rill of water oozing out of the earth, and resembling in look and taste, the water of the Missouri. Here they encamped for the night, and supped sumptuously upon their mountain mutton, which they found in good condition, and extremely well tasted.
The morning was bright, and intensely cold. Early in the day they came upon a stream running to the east, between low hills of bluish earth, strongly impregnated with copperas. Mr. Stuart supposed this to be one of the head waters of the Missouri, and determined to follow its banks. After a march of twenty-six miles, however, he arrived at the summit of a hill, the prospect of which induced him to alter his intention. He beheld, in every direction south of east, a vast plain, bounded only by the horizon, through which wandered the stream in question, in a south-south-east direction. It could not, therefore, be a branch of the Missouri. He now gave up all idea of taking the stream for his guide, and shaped his course towards a range of mountains in the east, about sixty miles distant, near which he hoped to find another stream.
The weather was now so severe, and the hardships of travelling so great, that he resolved to halt for the winter, at the first eligible place. That night they had to encamp on the open prairie, near a scanty pool of water, and without any wood to make a fire. The northeast wind blew keenly across the naked waste, and they were fain to decamp from their inhospitable bivouac before the dawn.
For two days they kept on in an eastward direction, against wintry blasts and occasional snow storms. They suffered, also, from scarcity of water, having occasionally to use melted snow;this, with the want of pasturage, reduced their old pack-horse sadly. They saw many tracks of buffalo, and some few bulls, which, however, got the wind of them, and scampered off.
On the 26th of October, they steered east-northeast, for a wooded ravine in a mountain, at a small distance from the base of which, to their great joy, they discovered an abundant stream, running between willowed banks. Here they halted for the night, and Ben Jones having luckily trapped a beaver, and killed two buffalo bulls, they remained all the next day encamped, feasting and reposing, and allowing their jaded horse to rest from his labors.
The little stream on which they were encamped, was one of the head waters of the Platte River, which flows into the Missouri;it was, in fact, the northern fork, or branch of that river, though this the travellers did not discover until long afterwards. Pursuing the course of this stream for about twenty miles, they came to where it forced a passage through a range of high hills, covered with cedars, into an extensive low country, affording excellent pasture to numerous herds of buffalo. Here they killed three cows, which were the first they had been able to get, having hitherto had to content themselves with bull beef, which at this season of the year is very poor. The hump meat afforded them a repast fit for an epicure.
Late on the afternoon of the 30th, they came to where the stream, now increased to a considerable size, poured along in a ravine between precipices of red stone, two hundred feet in height. For some distance it dashed along, over huge masses of rock, with foaming violence, as if exasperated by being compressed into so narrow a channel, and at length leaped down a chasm that looked dark and frightful in the gathering twilight.
For a part of the next day, the wild river, in its capricious wanderings, led them through a variety of striking scenes. At one time they were upon high plains, like platforms among the mountains, with herds of buffaloes roaming about them; at another among rude rocky defiles, broken into cliffs and precipices, where the blacktailed deer bounded off among the crags, and the bighorn basked in the sunny brow of the precipice.
In the after part of the day, they came to another scene, surpassing in savage grandeur those already described. They had been travelling for some distance through a pass of the mountains, keeping parallel with the river, as it roared along, out of sight, through a deep ravine. Sometimes their devious path approached the margin of cliffs below which the river foamed, and boiled, and whirled among the masses of rock that had fallen into its channel. As they crept cautiously on, leading their solitary pack-horse along these giddy heights, they all at once came to where the river thundered down a succession of precipices, throwing up clouds of spray, and making a prodigious din and uproar. The travellers remained, for a time, gazing with mingled awe and delight, at this furious cataract, to which Mr. Stuart gave, from the color of the impending rocks, the name of "The Fiery Narrows."
