I observe a great alteration in the Corrent course and appearance of this pt. of the Missouri. in places where there was Sand bars in the fall 1804 at this time the main Current passes, and where the current then passed is now a Sand bar Sand bars which were then naked are now covered with willow Several feet high. the enteranc of Some of the Rivers & Creeks Changed owing to the mud thrown into them, and a layor of mud over Some of the bottoms of 8 inches thick.

I dispatched one of the men to Capt Clark requesting him to send up a canoe to take down the meat we had killed and our baggage to his encampmt, which was accordingly complyed with. after I had completed my observations in the evening I walked down and joined the party at their encampment on the point of land fromed by the junction of the rivers; found them all in good health, and much pleased at having arrived at this long wished for spot, and in order to add in some measure to the general pleasure which seemed to pervade our little community, we ordered a dram to be issued to each person; this soon produced the fiddle, and they spent the evening with much hilarity, singing & dancing, and seemed as perfectly to forget their past toils, as they appeared regardless of those to come. in the evening, the man I had sent up the river this morning returned, and reported that he had ascended it about eight miles on a streight line; that he found it crooked, meandering from side to side of the valley formed by it; which is from four to five miles wide. the corrent of the river gentle, and it's bed much interrupted and broken by sandbars; at the distance of five miles he passed a large Island well covered with timber, and three miles higher a large creek falls in on the S. E. sides above a high bluff in which there are several stratas of coal. the country bordering on this river as far as he could percieve, like that of the Missouri, consisted of open plains. he saw several of the bighorned anamals in the couse of his walk; but they were so shy that he could not get a shoot at them; he found a large horn of one of these anamals which he brought with him. the bed of the yellowstone river is entirely composed of sand and mud, not a stone of any kind to be seen in it near it's entrance.
