The sunflower is in bloom [NB: Copy for Dr. Barton ] and abundant in the river bottoms. The Indians of the Missouri particularly those who do not cultivate maze make great uce of the seed of this plant for bread, or use it in thickening their soope.    they most commonly first parch the seed and then pound them between two smooth stones untill they reduce it to a fine meal.    to this they sometimes mearly add a portion of water and drink it in that state, or add a sufficient quantity of marrow grease to reduce it to the consistency of common dough and eate it in that manner.    the last composition I think much best and have eat it in that state heartily and think it a pallateable dish.    there is but little of the broad leafed cottonwood above the falls, much the greater portion being of the narrow leafed kind. [2]    there are a great abundance of red yellow perple & black currants, and service berries now ripe and in great perfection. I find these fruits very pleasent particularly the yellow currant [3] which I think vastly preferable to those of our gardens.    the shrub which produces this fruit rises to the hight of 6 or 8 feet; the stem simple branching and erect.    they grow closly ascociated in cops either in the oppen or timbered lands near the watercouses.    the leaf is petiolate of a pale green and resembles in it's form that of the red currant common to our gardens. [4]    the perianth of the fructification is one leaved, five cleft, abreviated and tubular, the corolla is monopetallous funnel-shaped; very long, superior, 〈permanent tho'〉 withering and of a fine orrange colour.    five stamens and one pistillum; of the first, the fillaments are capillare, inserted into the corolla, equal, and converging; the anther ovate, biffid and incumbent.    with rispect to the second the germ is roundish, smoth, inferior pedicelled and small; the style, long, and thicker than the stamens, simple, cylinderical, smooth, and erect, withering and remains with the corolla untill the fruit is ripe.    stigma simple obtuse and withering.—    the fruit is a berry about the size and much the shape of the red currant of our gardins, like them growing in clusters supported by a compound footstalk, but the peduncles which support the several berries are longer in this species and the berries are more scattered.    it is quite as transparent as the red current of our gardens, not so ascid, & more agreeably flavored.    the other species differ not at all in appearance from the yellow except in the colour and flavor of their berries. I am not confident as to the colour of the corolla, but all those which I observed while in blume as we came up the Missouri were yellow but they might possibly have been all of the yellow kind and that the perple red and black currants here may have corollas of different tints from that of the yellow currant.—    The survice berry differse somewhat from that of the U' States [5]    the bushes are small sometimes not more than 2 feet high and scarcely ever exceed 8 and are proportionably small in their stems, growing very thickly ascosiated in clumps.    the fruit is the same form but for the most part larger more lucious and of so deep a perple that on first sight you would think them black.—    there are two species of goosbirris [6] here allso but neither of them yet ripe.    the choke cherries also abundant and not yet ripe.    there is Box alder, red willow and a species of sumac here also.    there is a large pine tree situated on a small island at the head of these rappids above our cam[p]; it being the first we have seen for a long distance near the river I called the island pine island. [7] This range of the rocky mountains runs from S E to N. W.—    at 8 A. M. this morning Capt. Clark arrived with the party.    we took breakfast here, after which I had the box which contained my instruments taken by land arround tower rock to the river above the rappid; the canoes ascended with some difficulty but without loss or injury, with their loads.

Point of Observation No. 33. [8]

On the Stard. side of the Missouri one mile above the point of observation of this morning.

Observed Meridian Altitude of ☉'s L. L. with Octant by the back observation    56° 50'

Latitude deduced from this observation    46° 42' 14.7"

After making those observations we proceed, and as the canoes were still heavy loaded all persons not employed in navigating the canoes walled on shore.    the river clifts were so steep and frequently projecting into the river with their perpendicular points in such manner that we could not pass them by land, we wer therefore compelled to pass and repass the river very frequently in the couse of the evening.    the bottoms are narrow the river also narrow deep and but little current.    river from 70 to 100 yds. wide.    but little timber on the river    aspin constitutes a part of that little.    see more pine than usual on the mountains tho' still but thinly scattered.    we saw some mountain rams or bighorned anamals this evening, and no other game whatever and indeed there is but little appearance of any.    in some places both banks of the river are formed for a short distance of nearly perpendicular rocks of a dark black grannite of great hight; [9] the river has the appearance of having cut it's passage in the course of time through this solid rock.    we ascended about 6 miles this evening from the entrance of the mountain and encamped on the Stard. side where we found as much wood as made our fires. [10]    musquetoes still troublesome knats not as much so.—    Capt. C. now informed me that after I left him yesterday, he saw the poles of a large lodge in praire on the Stard. side of the river which was 60 feet in diameter and appeared to have been built last fall; there were the remains of about 80 leather lodges near the place of the same apparent date. This large lodge was of the same construction of that mentioned above the white bear Islands.    the party came on very well and encamped on the lower point of an island near the Stard. shore on that evening.    this morning they had set out early and proceeded without obstruction untill they reached the rappid where I was encamped.

Set out early this morning and Crossed the rapid at the Island Cald pine rapid with Some dificuelty, at this rapid I came up with Capt Lewis & party    took a Medn. altitude & we took Some Luner Observations &c. and proceeded on, the emence high Precipies oblige all the party to pass & repass the river from one point to another    the river confined in maney places in a verry narrow Chanel from 70 to 120 yards wide bottoms narrow without timber and maney places the mountain approach on both Sides, we observe great deel of Scattering pine on the mountains, Some aspin, Spruce [12] & fur trees    took a meridian altd. which gave for Lattitude 46° 42' 14" 7/10 N    we proceeded on verry well about 8 miles & Camped on the Stard Side    The river crooked bottoms narrow, Clifts high and Steep, I assended a Spur of the Mountain which I found to be highe & dificuelt of axcess, Containig Pitch Pine & Covered with grass    Scercely any game to be Seen    The yellow Current now ripe also the fussey red Choke Cheries [13] getting ripe    Purple Current are also ripe. Saw Several Ibex or mountain rams to day


July 17th Wednesday 1805. Capt. Lewis and the two men Stayed out all last night.    a clear morning    we Set out at Sunrise & proceeded on about 4 miles. Came to a verry bad rapid [14] where we found Capt. Lewis & the 2 men.    the Mountains make close to the River on each Side.    we left Some articles and doubled maned the canoes and them all over Safe which was about half a mile long, & roled white over the rocks, but by the assistance of the towing lines we got up all the canoes without Injury    Sent back for the other articles.    passed a large Spring jest above the rapids which heads about half a mile above or back under the mountain on Lard. Side.    proceeded on.    the mountains make close to the River & verry steep high pricipicies about 700 feet from the Surface of the water perpinticular & a Solid rock. Some Spots of pine and balsam fir [15] timbers & narrow bottoms on the points and high grass &C. Some willow & currents [16] of different kinds.    the current Swift.    the River about 100 yards wide.    we Came 11 miles this day and Camped on the Starbord Side in a narrow bottom.    a little cotton timber—


Wednesday 17th.    We set out early, and the morning was fine and pleasant. At 8 o'clock we came to Captain Lewis's camp, at a very rapid place of the river, and took breakfast. We had here to join the crews of two canoes together, to go up the rapids which were about half a mile long. The Missouri at this place is very narrow. At the head of these rapids a fine spring comes in on the south side, [17] which rises about a quarter of a mile from the river; and has a good deal of small cotton-wood and willows on its banks. There is also another spring below the rapids, but it sinks before it reaches the river. We proceeded on through the mountains, a very desert looking part of the country. Some of the knobs or peaks of these mountains, are 700 (perhaps some nearly 1200) feet high, all rock; and though they are almost perpendicular, we saw mountain sheep on the very tops of them. We saw few other animals to day. The general breadth of the river is 100 yards. We went 11 miles and encamped in a small bottom on the north side.


July 17th Wednesday 1805.    Capt. Lewis & 2 men Stayed out all night who went up the river yesty.    a clear morning.    we Set out at Sunrise and proceeded on.    about 4 miles came to a hard rapid, ½ a mile where the mountains make close to the river on each Side.    Capt. Lewis joined us    by the assistance of the towing line and double manning the canoes we took them all up Safe.    passed a large Spring which run from under the Mountain on S. S.    proceeded on    passed verry high Steep rocks & pricipices.    these rocky Mountains are broken & verry uneven & appear to be nearly a Solid rock.    Some parts of them thinly covered with P. pine and balsom fer timber &c.    Some of these knobs we allow to be 700 feet high and a Solid rock.    Mountain Sheep on the top of them though they are allmost perpenticular.    fine Springs in these mountains, but a desert part of the Country.    narrow bottoms on the points.    Some willow and high grass with a wide leaf.    the current verry rapid, and river Crooked, and only about 100 yards wide.    we Came 11 miles this day and Camped on the N. Side in a bottom a little cotton timber on it.    the Musquetoes troublesome.    we got pleanty of yallow currents [18] this day.—

Wednesday July 17th    Captain Lewis, and two of our party that went up the River Yesterday; staid out all last night; We set off at sunrise, and proceeded on about 4 Miles, when we came to a hard Rapid, where the mountains made close into the River on both sides of it.    Captain Lewis & the Men with him met us here, we double manned the Canoes, and towing lines, and with much difficulty got them all over safe.—    We continued on our way, & passed a large spring which run from under the Mountains on the South side of the River, and some very high Steep rocks & precipeces lying on both sides of the River.    The rocky mountains at this place, are very broken and uneven, and appear to be nearly a solid Rock.    Some part of them are thinly covered with Pine & balsam for timber.

Some of the knobs on these mountains appear to be from the nearest calculation that we can make 〈to be〉 700 feet high, and it appear'd to be a solid rock, We saw on the very top of those Nobs, Mountain sheep although they appear to be almost perpendicular, In these mountains we saw fine Springs.    The Country appears to be a mere desart, and some narrow bottoms are at the points toward the River, Willow and Grass grow in them, The grass grows high and has a broad leaf.—    The River at this place runs very Crooked & runs very Rapid, and is only about 100 Yards wide, We came 11 Miles this day & encamped on the North side of the River, in a bottom having, a few Cotton wood Trees growing on it.    We found a great plenty of Yellow currants this day, In the Evening the Musketoes was very trouble-some.—

1. Here begins Lewis's notebook journal Codex F, running to August 22, 1805. It was probably Biddle who drew a red vertical line through almost this entire entry, stopping at " pine island." (back)
2. As they approach the Rocky Mountains beyond the Great Falls, the expedition is reaching the western limit of the eastern cottonwood species Populus deltoides, which is being replaced by the western, montane, narrowlead cottonwood, P. angustifolia, as accurately noted. Little, 149-W. (back)
3. Lewis's yellow currant is the golden currant. The fruit color of this currant is highly variable between plants and varies from black to sometimes red or yellow. See also April 30, 1805. Booth & Wright, 107; Pursh, 104; Cutright (LCPN), 172 n. 1. (back)
4. The common red currant is Ribes sativum Syme, garden, or red, currant. Fernald, 751. (back)
5. The eastern serviceberry with which Lewis was probably familiar is Amelanchier arborea (Michx. f.) Fern., juneberry, a larger shrub or small tree occurring on the Missouri River to eastern Nebraska. The western serviceberry which occurs along the Missouri River from Montana to South Dakota is noted on April 20, 1805. Booth & Wright, 110; Barkley, 137–38. (back)
6. The two gooseberry species here are probably bristly, or redshoot, gooseberry and swamp currant, Ribes lacustre (Pers.) Poir, based on ecology and distribution. Lewis seems occasionally to have used the term gooseberry to describe currants. See June 18 and July 25, 1805. However, on July 20 he distinguished between the two. Booth & Wright, 107. (back)
7. Probably later Half-Breed Island. Atlas map 62; MRC map 79. (back)
8. Should be numbered 32; observation no. 33 comes under July 18, 1805. (back)
9. The rocks are composed of the Adel Mountains volcanics. Near here they are primarily laval breccias and ashfall tuffs but contain no granite. Their colors are dark red, purplish-red, dark grayish-green, and dark gray. (back)
10. In Lewis and Clark County, Montana, a few miles downstream from the Dearborn River, near where Interstate Highway 15 crosses the Missouri. Atlas map 62; MRC map 79. (back)
11. Evidently Lewis copied Clark's courses for July 16 and 17 after their reunion on the latter date—a possible indication that he was keeping Codex F day by day at this time. (back)
12. Clark notices Picea engelmannii (Parry) Engelm., Engelmann spruce. Little, 37-W. (back)
13. The use of "fuzzy" and "red" to desecribe choke cherries is problematic, since the fruits of choke cherry, even when young, are neither. This may be the buffaloberry which was noted earlier in the area and which has silver scurfy or "fuzzy" leaves, and may have ripening red fruits at this time. Booth & Wright, 160. (back)
15. The pine is ponderosa pine, and the balsam fir for this region is Douglas fir, Pseudotsuga menziesii (Mirb.) Franco. (back)
16. Any of a number of species of willow, Salix. Lewis discusses the currants and berries of the region in his entry for this day. (back)
17. Perhaps the "small run" noted in passing by Clark. (back)
18. See Lewis's entry for a discussion of the area's currants; this one is golden currant. (back)
