Saturday, September 15. We passed, at an early hour, the creek near our last night's encampment; and at two miles distance reached the mouth of White river, coming in from the south. We ascended a short distance, and sent a sergeant and another man to examine it higher up. This river has a bed of about three hundred yards, though the water is confined to one hundred and fifty: in the mouth is a sand island, and several sandbars. The current is regular and swift, with sandbars projecting from the points. It differs very much from the Platte, and Quieurre, in throwing out, comparatively, little sand, but its general character is like that of the Missouri. This resemblance was confirmed by the sergeant, who ascended about twelve miles; at which distance it was about the same width as near the mouth, and the course, which was generally west, had been interrupted by islands and sandbars. The timber consisted chiefly of elm; they saw pine burrs, and sticks of birch were seen floating down the river; they had also met with goats, such as we have heretofore seen; great quantities of buffaloe, near to which were wolves, some deer, and villages of barking squirrels. At the confluence of White river with the Missouri is an excellent position for a town; the land rising by three gradual ascents, and the neighbourhood furnishing more timber than is usual in this country. After passing high dark bluffs on both sides, we reached the lower point of an island towards the south, at the distance of six miles. The island bears an abundance of grapes, and is covered with red cedar: it also contains a number of rabbits. At the end of this island, which is small, a narrow channel separates it from a large sand island, which we passed, and encamped, eight miles on the north, under a high point of land opposite a large creek to the south, on which we observe an unusual quantity of timber. The wind was from the northwest this afternoon, and high, the weather cold, and its dreariness increased by the howlings of a number of wolves around us.
September 16, Sunday. Early this morning, having reached a convenient spot on the south side, and at one mile and a quarter distance, we encamped just above a small creek, which we called Corvus, having killed an animal of that genus near it. Finding that we could not proceed over the sandbars, as fast as we desired, while the boat was so heavily loaded, we concluded not to send back, as we originally intended, our third periogue, but to detain the soldiers until spring, and in the mean time lighten the boat by loading the periogue: this operation, added to that of drying all our wet articles, detained us during the day. Our camp is in a beautiful plain, with timber thinly scattered for three quarters of a mile, and consisting chiefly of elm, cottonwood, some ash of an indifferent quality, and a considerable quantity of a small species of white oak: this tree seldom rises higher than thirty feet, and branches very much; the bark is rough, thick and of a light colour; the leaves small, deeply indented, and of a pale green; the cup which contains the acorn is fringed on the edges, and embraces it about one half: the acorn itself, which grows in great profusion, is of an excellent flavour, and has none of the roughness which most other acorns possess; they are now falling, and have probably attracted the number of deer which we saw on this place, as all the animals we have seen are fond of that food. The ground having been recently burnt by the Indians, is covered with young green grass, and in the neighbourhood are great quantities of fine plums. We killed a few deer for the sake of their skins, which we wanted to cover the periogues, the meat being too poor for food: the cold season coming on, a flannel shirt was given to each man, and fresh powder to those who had exhausted their supply.
Monday, September 16. Whilst some of the party were engaged in the same way as yesterday, others were employed in examining the surrounding country. About a quarter of a mile behind our camp, and at an elevation of twenty feet above it, a plain extends nearly three miles parallel to the river, and about a mile back to the hills, towards which it gradually ascends. Here we saw a grove of plum-trees loaded with fruit, now ripe, and differing in nothing from those of the Atlantic states, except that the tree is smaller and more thickly set. The ground of the plain is occupied by the burrows of multitudes of barking squirrels, who entice hither the wolves of a small kind, hawks, and polecats, all of which animals we saw, and presumed that they fed on the squirrel. This plain is intersected nearly in its whole extent by deep ravines and steep irregular rising grounds from one to two hundred feet. On ascending the range of hills which border the plain, we saw a second high level plain stretching to the south as far as the eye could reach. To the westward, a high range of hills about twenty miles distant runs nearly north and south, but not to any great extent, as their rise and termination is embraced by one view, and they seemed covered with a verdure similar to that of the plains. The same view extended over the irregular hills which border the northern side of the Missouri; all around the country had been recently burnt, and a young green grass about four inches high covered the ground, which was enlivened by herds of antelopes and buffaloe; the last of which were in such multitudes, that we cannot exaggerate in saying that at a single glance we saw three thousand of them before us. Of all the animals we had seen the antelope seems to possess the most wonderful fleetness: shy and timorous they generally repose only on the ridges, which command a view of all the approaches of an enemy: the acuteness of their sight distinguishes the most distant danger, the delicate sensibility of their smell defeats the precautions of concealment, and when alarmed their rapid career seems more like the flight of birds than the movements of an earthly being. After many unsuccessful attempts, captain Lewis at last, by winding around the ridges, approached a party of seven, which were on an eminence, towards which the wind was unfortunately blowing. The only male of the party frequently encircled the summit of the hill, as if to announce any danger to the females, who formed a group at the top. Although they did not see captain Lewis, the smell alarmed them, and they fled when he was at the distance of two hundred yards: he immediately ran to the spot where they had been, a ravine concealed them from him, but the next moment they appeared on a second ridge at the distance of three miles. He doubted whether it could be the same, but their number and the extreme rapidity with which they continued their course, convinced him that they must have gone with a speed equal to that of the most distinguished racehorse. Among our acquisitions to-day was a mule-deer, a magpie, the common deer, and buffaloe: captain Lewis also saw a hare, and killed a rattlesnake near the burrows of the barking squirrels.
Tuesday, September 18. Having everything in readiness we proceeded, with the boat much lightened, but the wind being from the N.W. we made but little way. At one mile we reached an island in the middle of the river, nearly a mile in length, and covered with red cedar; at its extremity a small creek comes in from the north; we then met some sandbars, and the wind being very high and ahead, we encamped on the south, having made only seven miles. In addition to the common deer, which were in great abundance, we saw goats, elk, buffaloe, the black tailed deer; the large wolves too are very numerous, and have long hair with coarse fur, and are of a light colour. A small species of wolf about the size of a gray fox was also killed, and proved to be the animal which we had hitherto mistaken for a fox: there are also many porcupines, rabbits, and barking squirrels in the neighbourhood.

September 19. We this day enjoyed a cool clear morning, and a wind from the southeast. We reached at three miles a bluff on the south, and four miles farther, the lower point of Prospect island, about two and a half miles in length; opposite to this are high bluffs, about eighty feet above the water, beyond which are beautiful plains gradually rising as they recede from the river: these are watered by three streams which empty near each other; the first is about thirty-five yards wide, the ground on its sides high and rich, with some timber; the second about twelve yards wide, but with less timber; the third is nearly of the same size, and contains more water, but it scatters its waters over the large timbered plain, and empties itself into the river at three places. These rivers are called by the French Les trois rivieres des Sioux, the three Sioux rivers; and as the Sioux generally cross the Missouri at this place, it is called the Sioux pass of the three rivers. These streams have the same right of asylum, though in a less degree than Pipestone creek already mentioned.
Two miles from the island we passed a creek fifteen yards wide; eight miles further, another twenty yards wide; three miles beyond which, is a third of eighteen yards width, all on the south side: the second which passes through a high plain we called Elm creek; to the third we gave the name of Night creek, having reached it late at night. About a mile beyond this is a small island on the north side of the river, and is called Lower island, as it is situated at the commencement of what is known by the name of the Grand Detour, or Great Bend of the Missouri. Opposite is a creek on the south about ten yards wide, which waters a plain where there are great numbers of the prickley pear, which name we gave to the creek. We encamped on the south, opposite the upper extremity of the island, having made an excellent day's sail of twenty six and a quarter miles. Our game this day consisted chiefly of deer, of these four were black tails, one a buck with two main prongs of horns on each side and forked equally. Large herds of buffaloe, elk and goats, were also seen.
Thursday, September 20. Finding we had reached the Big Bend, we despatched two men with our only horse across the neck, to hunt there and wait our arrival at the first creek beyond it. We then set out with fair weather and the wind from S.E. to make the circuit of the bend. Near the lower island the sandbars are numerous, and the river shallow. At nine and a half miles is a sand island, on the southern side. About ten miles beyond it is a small island on the south, opposite to a small creek on the north. This island, which is near the N.W. extremity of the bend, is called Solitary island. At about eleven miles further, we encamped on a sandbar, having made twenty-seven and a half miles. Captain Clarke, who early this morning had crossed the neck of the bend, joined us in the evening. At the narrowest part, the gorge is composed of high and irregular hills of about one hundred and eighty or one hundred and ninety feet in elevation; from this descends an unbroken plain over the whole of the bend, and the country is separated from it by this ridge. Great numbers of buffaloe, elk, and goats are wandering over these plains, accompanied by grouse and larks. Captain Clarke saw a hare also, on the Great Bend. Of the goats killed to-day, one is a female differing from the male in being smaller in size; its horns too are smaller and straighter, having one short prong, and no black about the neck: none of these goats have any beard, but are delicately formed, and very beautiful.
Friday, September 21. Between one and two o'clock the serjeant on guard alarmed us, by crying that the sandbar on which we lay was sinking; we jumped up, and found that both above and below our camp the sand was undermined and falling in very fast: we had scarcely got into the boats and pushed off, when the bank under which they had been lying, fell in, and would certainly have sunk the two periogues if they had remained there. By the time we reached the opposite shore the ground of our encampment sunk also. We formed a second camp for the rest of the night; and at daylight proceeded on to the gorge or throat of the Great Bend, where we breakfasted. A man, whom we had despatched to step off the distance across the bend, made it two thousand yards: the circuit is thirty miles. During the whole course, the land of the bend is low, with occasional bluffs; that on the opposite side, high prairie ground, and long ridges of dark bluffs. After breakfast, we passed through a high prairie on the north side, and a rich cedar lowland and cedar bluff on the south, till we reached a willow island below the mouth of a small creek. This creek, called Tyler's river, is about thirty-five yards wide, comes in on the south, and is at the distance of six miles from the neck of the Great Bend. Here we found a deer, and the skin of a white wolf, left us by our hunters ahead: large quantities of different kinds of plover and brants are in this neighbourhood, and seen collecting and moving towards the south; the catfish are small, and not in such plenty as we had found them below this place. We passed several sandbars, which make the river very shallow and about a mile in width, and encamped on the south, at the distance of eleven and a half miles. On each side the shore is lined with hard rough gulleystones, rolled from the hills and small brooks. The most common timber is the cedar, though, in the prairies, there are great quantities of the prickly pear. From this place we passed several sandbars, which make the river shallow, and about a mile in width. At the distance of eleven and a half miles, we encamped on the north at the lower point of an ancient island, which has since been connected with the main land by the filling up of the northern channel, and is now covered with cottonwood. We here saw some tracks of Indians, but they appeared three or four weeks old. This day was warm.
September 22. A thick fog detained us until seven o'clock; our course was through inclined prairies on each side of the river, crowded with buffaloe. We halted at a point on the north side, near a high bluff on the south, and took a meridian altitude, which gave us the latitude of 44° 11' 33-3/10". On renewing our course, we reached first a small island on the south, at the distance of four and a half miles, immediately above which is another island opposite to a creek fifteen yards wide. This creek, and the two islands, one of which is half a mile long, and the second three miles, are called the Three Sisters: a beautiful plain extending on both sides of the river. This is followed by an island on the north, called Cedar island, about one mile and a half in length and the same distance in breadth, and deriving its name from the quality of the timber. On the south side of this island, is a fort and a large trading house, built by a Mr. Loisel, who wintered here during the last year, in order to trade with the Sioux, the remains of whose camps are in great numbers about this place. The establishment is sixty or seventy feet square, built with red cedar and picketted in with the same materials. The hunters who had been sent ahead joined us here. They mention that the hills are washed in gullies, in passing over which, some mineral substances had rotted and destroyed their moccasins; they had killed two deer and a beaver. At sixteen miles distance we came to on the north side at the mouth of a small creek. The large stones which we saw yesterday on the shores are now some distance in the river, and render the navigation dangerous. The musquitoes are still numerous in the low grounds.
