2.Lewis to his mother, from Fort Mandan, March 31, 1805, writing about "the open or prarie country" north of the Platte River: "...I had been led to believe, that it was barren, steril and sandy; but on the contrary I found it fertile in the extreem, the soil being from one to 20 feet in debth, consisting of a fine black loam, intermixed with a sufficient quantity of sand only to induce a luxuriant growth of grass and other vegitable productions..."

3.Lewis to his mother, from Fort Mandan, March 31, 1805, writing about the scarcity of timber north of the Platte River:"This want of timber is by no means attributeable to a deficiency in the soil to produce it, but ows it's orrigine to the ravages of the fires, which the natives kindle in these plains at all seasons of the year"

4.Lewis on the fertility of the soil near the mouth of the Osage River: "The country watered by this river, is generally level & fertile." The soil on the bottom lands "consists of a black rich loam many feet in debth. the uplands also consist of a dark loam overlaying a yellow or red clay"
