Set out early and continued down the S W bank of the river--

N 75 E   24 m.  to our encampment in a grive of cottonwood timber. [The camp was on the south side of Sun River some four to five miles northwest of the city of Great Falls, MT.]  the latter part of this course for 7 miles there is no timber in the river bottom, the other parts of the river possesses bottoms of the wide leafed cottonwood. [Plains Cottonwood.]   much the greater part of the bottom is untimbered.  the bottoms are wide and level  the high praries or plains are also beautiful level and smooth. great quantities of prickly pear of two kinds on the plains. [Brittle Prickly Pear, Opuntia fragilis and Plains Prickly Pear, O. polyacantha.]  the ground is rendered so miry by the rain which fell yesterday that it is excessively fatiegueing to the horses to travel.  we came 10 miles and halted for dinner  the wind blowing down the river in the fore part of the day was unfavourable to the hunters.  they saw several gangs of Elk but they having the wind of them ran off.  in the evening the wind set from the West and we fell in with a few elk of which R. Fields and myself killed 3 one of which swam the river and fell on the opposite so we threfore lost it's skin.   I sent the packhorses on with Sergt. Gass directing them to halt and encamp at the first timber which proved to be about 7 ms. I retained frazier to assit in skinning the Elk.  we wer about this time joined by drewer.  a large brown bear swam the river near where we were and drewyer shot and killed it.  by the time we butchered the 2 elk and bar it was nearly dark  we loaded our horses with the best of the meat and pursud the party and found them encamped as they had been directed in the first timber.  we did not reach them until 9 P.M.  they informed us that they had seen a very large bear in the plains which had pursued Sergt. Gass and Thomson some distance but their horses enabled them to keep out if it's reach.  they were affraid to fire on the bear laeast their horses should throw them as they were unaccustomed to the gun.   we killed five deer 3 Elk and a bear today  saw vast herds of buffaloe in the evening below is on the river.  <he> we hered them bellowing about us all night.  vast assemblages of wolves.  saw a large herd of Elk making down the river.  passed a considerable rapid in medicine river after dark.  the river about a hundred yards wide is deep and in many parts rappid and today has been much crouded with islands.  from our encampment down we know the river and thre is no rapid and scarcely any courant.  goosberies [Bristly, or Redshoot, Gooseberry, Ribes setosum is the most likely, but White-Stem Gooseberry, R. inerme is also a possibility.] are very abundant of the common red kind and are begining to ripen.  no currants on this river.  both species of the prickly pears just in blume.--

At dark last evening the weather cleared up, and was cold all night. This morning was clear and cold, and all the mountains in sight were covered with snow, which fell yesterday and last night. At 8 o'clock we started down the river, and in the course of the day our hunters killed five deer, two elk and a bear. The road was a very muddy [sic] after the rain. The country on both sides is composed of beautiful plains; the river about 80 yards wide and tolerably straight, with some cotton wood timber on its banks; and plenty of game of different kinds ranging through the plains. Having made 24 miles we encamped for the night.

[The following is a summary of Lewis's route from Traveler's Rest to Sun River, July 3-10, 1806.  It was written by Clark and placed here by it's last date. Clark apparently received this information after the men reunited in August 1806.]

The most derect and best Course from the dividing ridge which divides the wates of the Columbia from those of the Missouri at the Gap where Capt Lewis crossed it is to leave a Short range of mountains which pass the missouri at the Pine Island rapid to the right passing at it's base and through the plains pass fort mountan to the White bear Isds or medecine river, a fine road and about 45 miles, reducing the distance from Clarks river to 145 miles--  one other road passes from the enterance of Dearborns River over to a South branch of the Cohahlarishkit river.

Last night was very cold and this morning everything was white with frost and the grass Stiff frozend.  I had Some water exposed in a bason in which the ice was 3/4 of an inch thick this morning.  I had all the Canoes put into the water and every article which was intended to be Sent down put on board, and the horses collected and packed with what fiew articles I intend takeing with me to the River Rochejhone, and after brackfast we all Set out at the Same time [Ordway indicates that he was in charge of the canoe party, while Clark led the group with the horses on land.] & proceeded on Down Jeffersons river on the East Side through Sarviss [NB: Service] Vally and rattle snake mountain [They were traveling northeast down the Beaverhead River. See August 10, 1805.] and into that butifull and extensive Vally open and fertile which we Call the beaver head Vally which is the Indian name  in their language Har na Hap pap Chah. [The valley of the Beaverhead and upper Jefferson Rivers. For the Beaverhead Rock, which Clark passed the next day on this downriver trip, see entries for August 8-10, 1805.]  from the No. of those animals in it & a pt. of land resembling the head of one  this Vally extends from the rattle Snake Mountain down Jeffersons river as low as fraziers Creek [South Boulder River; See August 1, 1805.] above the big horn maountain and is from 12 [NB: 10] to 30 [NB: 15] miles in width and [blank] [NB: about 50] miles on a direct line in length and Jeffersons river in passing through this Vally reives McNeals Creek [Blacktail Deer Creek near Dillon, MT. See August 10 & 13, 1805.], Track Creek [Rattlesnake Creek reaching the Beaverhead a few miles above Dillon; See August 14, 1805.], Phalanthrophy river, Wisdom river [Ruby (Philanthropy) and Big Hole (Wisdom) rivers near Twin Bridges, MT. See entries for August 5-6, 1805.], Fields river [Boulder River ("R Fields Vally Creek" on Clark's map) meeting Jefferson River. See August 1, 1805.] and Fraziers Creek each throw in a considerable quantity of water and have innoumerable beaver and otter on them; the bushes in their low bottoms are the resort for great numbers of Deer, and in the higher parts of the Vally we see Antelopes scattered feeding.  I saw also on the Sides of the rock in rattle snake mountain 15 big horn animals, those animals feed on the grass which grow on the Sides of the mountn. and in the narrow bottoms on the Water courses near the Steep Sides of the mountains on which they can make their escape from the pursute of wolves Bear &c.   at Meridian I halted to let the horses Graze having Come 15 Miles   I ordered the [NB: canoes] to land.  Sergt. Ordway informed me that the party with him had Come on very well, and he thought the Canoes could go as farst as the horses &c. as the river now become wider and not So Sholl, I deturmined to put all the baggage &c. which I intend takeing with me to the river Rochejhone in the canoes and proceed on down with them myself to the 3 forks or Madisons & galletens rivers. leaveing the horses to be taken down by Sergt. Pryor and 6 of the men of the party to accompany me to the river Rochejhone and directed Sergt. Pryor to proceed on moderately and if possible encamp with us every night.  after dinner had my baggage put on board and Set out, and proceeded on tolerable well to the head of the 3000 Mile Island on which we had encamped on the [NB: 11th] of Augt last. [The island on which the party camped on August 11, 1805, according to Clark's map, was labeled "Otter Isd." "3000 Mile Island" is three to four miles farther down the Beaverhead River, approximately ten miles northeast of Dillon.]   the Canoes passed Six of my encampments assending [Clark's camps of August 11-16, 1805.], opposit this island I encamped on the East side. [The East bank of Jefferson River opposite Three Thousand Mile Island.]   the Musquetors were troublesom all day and untill one hour after Sunset when it became Cool and they disappeared.  in passing down in the Course of this day we saw great numbers of beaver lying on the Shores in the Sun.  wild young Gees and ducks are common in this river.  we killed two young gees this evening.  I saw several large rattle Snakes in passing the rttle Snake Mountain  they were fierce.
