Lewis, July 29, 1806

Tuesday July 29th 1806. Shortly after dark last evening a violent storm came on from N. W. attended with rain hail Thunder and lightning which continued the greater part of the night. no having the means of making a shelter I lay in the water all night. the rain continued with but little intermission all day. I intend halting as soon as the weather proves fair in order to dry our baggage which much wants it. I placed the two Fieldses and Colter and Collins in the two smallest canoes with orderes to hunt, and kill meat for the party and obtain as many Elkskins as are necessary to cover our canoes and furnish us with shelters from the rain. we set out early and the currant being strong we proceeded with great rapidity. at 11 A.M. we passed that very interesting part of the Missouri where the natural walls appear, particularly discribed in my outward bound journey. we continued our rout untill late in the evening and encamped on the N. E. side of the river at the same place we had encamped on the 29th of May 1805. on our way today we killed 9 bighorns of which I preserved the skins and skeletons of 2 females and one male; the flesh of this aninmal is extreemly delicate tender and well flavored, they are now in fine order. their flesh both in colour and flavor much resembles mutton though it is not so strong as our mutton. the eye is large and prominant, the puple of a pale sea green and iris of a light yellowish brown colour. these animals abound in this quarter keeping themselves principally confined to the steep clifts and bluffs of the river. we saw immence hirds of buffaloe in the high plains today on either hand of the river. saw but few Elk. the brown Curloo has left the plains I presume it has raised it's young and retired to some other climate and country. as I have been very particular in my discription of the country as I ascended this river I presume it is unnecesssesary here to add any-thing further on that subject. the river is now nearly as high as it has been this season and is so thick with mud and sand that it is with difficulty I can drink it. every little rivulet now discharges a torrant of water bringing down immece boddies of mud sand and filth from the plains and broken bluffs.-
