On the Marias, Lewis waits for clear weather to make navigational measurements. Clark heads down the Yellowstone River two small canoes lashed together. He asks Pryor, Shannon, and Windsor to take the remaining horses to the Mandan.

at 8 A M. we Set out and proceeded on very well to a riffle    at this riffle the Small Canoes took in a good deel of water which obliged us to land...to dry our articles and bail the Canoes.
