What is "wenatchi"

The Wenatchi people are a group of Native Americans who originally lived in the region near the confluence of the Columbia and Wenatchee Rivers in Eastern Washington State. They spoke Interior Salish (a variant of Salish) and ate salmon, starchy roots like camas and biscuitroot, berries, deer, sheep and whatever else they could hunt or catch. The river that they lived on, the Wenatchee River, had one of the greatest runs of salmon in the world prior to numerous hydroelectric dams being put in on the downstream Columbia, pollution and other issues, and was their main food source.
