The Yakama are a Native American tribe with nearly eleven thousand members, based primarily in eastern Washington state. The Yakama people today are enrolled in the federally recognized tribe named the Confederated Tribes and Bands of the Yakama Nation. The Yakama people are similar to the other native inhabitants of the Columbia River Plateau. The lands of the Yakama originally extended in all directions along the Cascade Mountain Range to the Columbia River and beyond. They were hunters and gatherers well-known for trading salmon harvested from annual runs in the Columbia River. In 1805 or 1806, they were among the tribes to have encountered the Lewis and Clark Expedition at the confluence of the Yakima River and Columbia River as the expedition neared the Pacific Ocean. Later interactions with the U.S. Government were not as pleasant. As a consequence of the Walla Walla Council and the Yakima War of 1855, the tribe was forced to cede much of their land and move onto their present reservation. The Treaty of 1855 identified the 14 confederated tribes and bands of the Yakama
