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.
