What was the environment that the pawnee tribe lived in?
Pawnee. A confederacy belonging to the Caddoan family. The name is probably derived from parika, a horn, a term used to designate the peculiar manner of dressing the scalp-lock, by which the hair was stiffened with paint and fat, and made to stand erect and curved like a horn.This marked features of the Pawnee gave currency to the name and its application to cognate tribes. The people called themselves Chahiksichahiks, `men of men.’ In the general north east wardly movement of the Caddoan tribes the Pawnee seem to have brought up the rear. Their migration was not in a compact body, but in groups, whose slow progress covered long periods of time. The Pawnee tribes finally established themselves in the valley of Platte river, Nebr., which territory, their traditions say, was acquired by conquest, but the people who were driven out are not named. It is not improbable that in making their way north east the Pawnee may have encountered one or more waves of the southward movements of Shoshon
