Tuesday 23. A clear and pleasant morning, but at nine o’clock the wind became so high that the boats were in danger of upsetting; we therefore were forced to stop at a place of safety till about five in the afternoon, when the wind being lower we proceeded and encamped on the north at the distance of thirteen and a half miles: the party on shore brought us a buffaloe calf and three blacktailed deer: the sand on the river has the same appearances as usual, except that the quantity of wood increases.
Wednesday 24. The wind blew so high during the whole day that we were unable to move; such indeed was its violence, that although we were sheltered by high timber the waves wet many articles in the boats: the hunters went out and returned with four deer, two elk, and some young wolves of the small kind. The party are very much afflicted with sore eyes, which we presume are occasioned by the vast quantities of sand which are driven from the sandbars in such clouds as often to hide from us the view of the opposite bank. The particles of this sand are so fine and light that it floats for miles in the air like a column of thick smoke, and is so penetrating that nothing can be kept free from it, and we are compelled to eat, drink, and breathe it very copiously. To the same cause we attribute the disorder of one of our watches, although her cases are double and tight; since without any defect in its works, that we can discover, it will not run for more than a few minutes without stopping.
Thursday 25. The wind moderated this morning, but was still high; we therefore set out early, the weather being so cold that the water froze on the oars as we rowed, and about ten o’clock the wind increased so much that we were obliged to stop. This detention from the wind and the reports from our hunters of the crookedness of the river, induced us to believe that we were at no great distance from the Yellowstone river. In order therefore to prevent delay as much as possible, captain Lewis determined to go on by land in search of that river, and make the necessary observations, so as to be enabled to proceed on immediately after the boats should join him; he therefore landed about eleven o’clock on the south side, accompanied by four men; the boats were prevented from going until five in the afternoon, when they went on a few miles further and encamped for the night at the distance of fourteen and a half miles.
Friday 26. We continued our voyage in the morning and by twelve o’clock encamped at eight miles distance, at the junction of the Missouri and Yellowstone rivers; where we were soon joined by captain Lewis.
