On the advice of the keelboat captain, Lewis heads down the Ohio River before the morning fog has cleared. They stop on a sand bar opposite Oldtown Creek to dry the wet cargo. Many rusty iron goods such as tomahawks and guns are oiled.

I found on opening the goods that many of the articles were much Injured; particularly the articles of iron, which wer rusted very much    my guns, tomehawks, & knives were of this class; I caused them to be oiled and exposed to the sun    the clothing of every discription also was opened and aired, we busily employed in this business all hands, from ten in the morning untill sun seting

At Plum Camp near present Oacoma, Lewis attempts to collect a female pronghorn and is surprised by how fast they can run. Colter kills a new type of deer, later named a mule deer. Lewis describes the black-billed magpie and coyote.

this senery already rich pleasing and beatiful, was still farther hightened by immence herds of Buffaloe deer Elk and Antelopes which we saw in every direction feeding on the hills and plains. I do not think I exagerate when I estimate the number of Buffaloe which could be compreed at one view to amount to 3000.

We ascended some very high mountains, & very rockey paths & many bare places on the Mountains & high Rocks Standing upright on them.
