a violent hard rain about day light this morning. all wet except myself and the indians. we embarked a little after Sun rise wind moderate and ahead. we proceeded on at meridn. passed the enterance of Cannonball river imediately above is the remains of a large Sieoux encampment which appears to have been made this Spring. at 3 P M passed the enterance of Wardepon River Saw great number of wolves on the bank Some Buffalow & Elk, tho not so abundant as near the River Rochejhone. passed the place where we left the last encampment of Ricaras in the fall 1804 and encamped on a Sandbar from the N. E. Side, having made 8 miles only, the wind blew hard all day which caused the waves to rise high and flack over into the Small Canoes in Such a manner as to employ one hand in throwing the water out. The plains begin to Change their appearance the grass is turning of a yellow colour. 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.
