Answer:
Actually, Nez Percé, self-name Nimi’ipuu, North American Indian people whose traditional territory centred on the lower Snake River and such tributaries as the Salmon and Clearwater rivers in what is now northeastern Oregon, southeastern Washington, and central Idaho, U.S. They were the largest, most powerful, and best-known of the Sahaptin-speaking peoples. They call themselves the Nimi’ipuu but were known by various names by other groups. The French called them the Nez Percé (“Pierced Nose”), having mistakenly identified individuals whom they saw wearing nose pendants as members of the Nimi’ipuu, though the Nimi’ipuu do not pierce their noses. As inhabitants of the high plateau region between the Rocky Mountains and the coastal mountain system, the Nez Percé are considered to be Plateau Indians. Historically, as one of the easternmost Plateau groups, they also were influenced by the Plains Indians just east of the Rockies. Like other members of this culture area, the Nez Percé domestic life traditionally centred on small villages located on streams having abundant salmon, which, dried, formed their main source of food. They also sought a variety of game, berries, and roots. Their dwellings were communal lodges, A-framed and mat-covered, varying in size and sometimes housing as many as 30 families.

Moreover, this feature of rivers makes them useless in regards to transportation, which caused the interior area of the country to be unexplored for a long time. This is explained in "People could not penetrate it by following waterways". Also due to this, explorations occurred by land but this limited the exploration. According to this, one effect of rivers was "Exploration was limited because there were no rivers on which to travel Into the Interior."
