Clark: August 20, 1806

Wednesday 20th of August 1806 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.
