Kettle Falls was the largest waterfall of the Columbia River. Kettle Falls was for over 10,000 years a major indigenous fishing and trade site. In 1940, they were dammed by the Grand Coulee and formed Lake Roosevelt.
American Buffalo, or bison, was a staple of many Native diets, but had disappeared by the 1820s from most places west of the Clark Fork. Modern revival efforts by the Yakama nation have brought bison back.
