Pocasse

Pocasse was an Arikara leader whose name is associated with the Missouri River country of the northern Plains. In October 1804 the Lewis and Clark expedition visited Arikara villages above the Grand River and met Pocasse, also recorded as Hay. At his house the visitors received corn, leggings and tobacco, including seeds of two kinds. Arikara communities lived in earth-lodge villages and cultivated crops along the river, while taking part in the trade that connected peoples of the Missouri valley.
