The hills and river clifts which we pass to day exhibit a most romantic appearance. The Bluffs of the river rise to the hight of from 2 to 300 feet and in most places nearly perpendicular; they are formed of remarkable white Sandstone which is Sufficiently Soft to give way readily to the impression of water; two or three thin horizontal Stratas of white free Stone, on which the rains or water make no impression, lie imbeded in those clifts of Soft Stone near the upper part of them; the earth on the top of these clifts is a dark rich loam, which forming a gradual ascending plain extend back from 1/2 a mile to a mile where the hills commence and rise abruptly to the hight of about 300 feet more. The water in the Course of time acecending from those hills and plains on either Side of the river has trickled down the Soft Sand Clifts and woarn it into a thousand grotesque figures; which with the help of a little imagination and an oblique view at a distance are made to represent elegant ranges of lofty freestone buildings, haveing their parapets well Stocked with Statuary; Colloms of various Sculptures both Grooved and plain, are also Seen Supporting long galleries in part of those buildings; in other places on a much nearer approach and with the with the help of less immagination we See the remains of ruins of eligant buildings; Some Collumns Standing and almost entire with their pedestals and Capitals, others retaining their pedestals but deprived by time or accedint of their capitals, Some lying prostrate and broken, others in the form of vast Pyramids of connic Structure bearing a Serious of other pyramids on their tops becomeing less as they ascend and finally termonateing in a Sharp point. nitches and alcoves of various forms and Sizes are Seen at different hights as we pass. a number of the Small martin which build their nests with Clay of a globular form attached to the wall within those nitches, and which were Seen hovering about the top of the collumns did not the less remind us of Some of those large Stone buildings in the United States. The thin Stratas of hard free Stone intermixed with the Soft Sand Stone Seems to have aided the water in forming this Curious Scenery.
as we passed on it Seemed as if those Seens of Visionary enchantment would never have an end; for here it is too that nature presents to the view of the traveler vast ranges of walls of tolerable workmanship, So perfect indeed are those walls that I Should have thought that nature had attempted here to rival the human art of Masonry had I not recollected that She had first began her work. These walls rise to the hight in many places of 100 feet, are perpindicular, with two regular faces, and are from one to 12 feet thick, each wall retains the Same thickness to the top which it possesses at bottom. The Stone of which these walls are formed is black, dense and dureable, and appears to be Composed of a large portion of earth intermixed or Cemented with a Small quantity of Sand and a Considerable portion of quarts. these Stones are almost invariably regular parallelepipeds, of unequal Sizes in the wall, but equal in their horizontal ranges, at least as to debth. These are laid regularly in ranges on each other like bricks, each breaking or covering this interstice of the two on which it rests, thus the pirpendicular interstices are broken, and the horizontal ones extend entire throughout the whole extent of the walls. These Stones Seam to bear Some proportion to the thickness of the walls in which they are employd, being larger in the thicker walls; the greatest length of the parallelepiped appear to form the thickness of the thiner walls, while two or more are employed to form that of the thicker walls. Those walls pass the river in Several places rising from the waters edge much above the Sand Stone Bluffs, which they Seam to penetrate; thence Continueing their course on a Streight line on either Side of the river thorough the gradually ascending plains over which they tower to the hight of from ten to 90 feet untill they reach the hills which they finally enter and Conceal themselves. these walls Sometimes run parallel to each other, with Several ranges near each other, and at other times intersecting each other at right angles, haveing the appearance of the walls of ancient houses or gardins. both Capt Lewis and My self walked on Shore this evening and examined those walls minutely and preserved a Specimine of the Stone.—I found many clifts of very excellent free Stone of a light yellowish brown Colour. Capt. Lewis observed a Species of pine which I had never Seen, it differs from the pitch pine in the particular of its leaf and Cone, the first being partly Shorter, and the latter considerably longer and more pointed. The appearance of Coal Continues but in Smaller quantities, but little appearance of burnt hills or pumicestone. the mineral Salt in Some measure have abated and no quarts. we Saw a great number of the Big Horn, Some mule deer, and a few Buffalow and Elk, no antelopes or Common Deer-. Capt. Lewis killed a Big horn animal. the party killed 2 Buffalow one Elk and a Big horn or Ibex to day-. The river has been from 150 to 250 yards wide but little timber on the river to day. river less muddy than it was below.

Saturday June 1st 1805 The moring was cloudy and a few drops of rain. Set out at an early hour and proceeded as usual by the help of our chords. the river Clifts and bluffs not so high as yesterday and the country becomes more level. a mountain or a part of the N. Mountain appears to approach the river within 8 or 10 ms. bearing N. from our encampment of the last evening. Capt C. who walked on shore today informed me that the river hills were much lower than usual and that from the tops of those hills he had a delightfull view of rich level and extensive plains on both sides of the river; in those plains, which in many places reach the river clifts, he observed large banks of pure sand which appeared to have been driven by the S W. winds from the river bluffs and there deposited. the plains are more fertile at some distance from the river than near the bluffs where the surface of the earth is very generally covered with small smothe pebbles which have the appearance of having been woarn by the agitation of the waters in which they were no doubt once immerced. A range of high Mountains appear to the S. W. at a considerable distance covered with snow, they appear to run Westerly. no timber appears on the highlands; but much more than yesterday on the river and Islands. rockey points and shoals less freequent than yesterday but some of them quite as bad when they did occur. the river from 2 to 400 yards wide, courant more gentle and still becoming clearer. game is by no means as abundant as below; we killed one male bighorn and a mule deer today; saw buffalow at a distance in the plains particularly near a small Lake on Lard. side about 8 ms. distant. some few drops of rain again fell this evening. we passed six Islands and encamped on the 7th; they are all small but contain some timber. the wind has been against us all day.—I saw the choke cherry the yellow and red courant bushes; the wild rose appears now to be in full bloom as are also the prickley pear which are numerous in these plains.—We also saw some Indian Lodges of sticks today which did not appear to have been long evacuated.—some coal appear in the bluffs.

June 1st Satterday 1805 a Cloudy morning we Set out at an early hour and proseeded on as usial with the toe rope The Countrey appears to be lower and the Clifts not So high or Common, a mountain or a part of the north Mountain about 8 or 10 miles N. of this place, I walked on Shore to day found the Plains much lower than we have Seen them and on the top we behold an extencive plain on both Sides, in this plain I observed maney noles of fine Sand which appeared to have blown from the river bluffs and collected at these points Those plains are fertile near the river a great no. of Small Stone, I observed at Some distance to the S. W. a high mountain which appears to bear westerly The Cole appear as usial, more Cotton trees Scattered on the Shores & Islands than yesterday—no timber on the high land, the river from 2 to 400 yards wide & current more jentle than yesterday but fiew bad rapid points to day—the wild animals not So plenty as below we only killed a ram & mule Deer to day, we Saw Buffalow at a distance in the plains, particularly near a Lake on the Lard. Side about 8 miles distant from the river—We passed Six Islands and encamped on the 7th all those Islands are Small but contain Some timber on them The river riseing a little Wind to day from the S. W. Som fiew drops of rain in the morning and also in the evening, flying Clouds all day
Saw Several Indian camps made of Sticks & bark Set up on end and do not appear to belong evacuated—The roses are in full bloome, I observe yellow berries, red berry bushes Great numbers of Wild or choke Cheries, prickley pares are in blossom & in great numbers
