Northwest of Walla Walla at the confluence of the Snake and Columbia Rivers lies Sacajawea State Park and Interpretive Center (509-545-2361), named for the amazing Shoshone Indian Girl who served as Lewis and Clark's interpreter. Interactive exhibits and Native American artifacts are among its offerings.
A Lewis and Clark Interpretive Sign in Richland marks the Expedition's furthest point up-rive on the Columbia. It is located at the intersection of Columbia Center Blvd. and Columbia Drive -- which incidentally, is the first federal highway ever built.
The East Benton County Historical Museum (509-582-7704) in Kennewick focuses on the pioneer settlers who followed Lewis and Clark.
A 200-mile, self-guided "Lewis and Clark Trail Historical Day Tour" includes numerous points of interest within three counties. Call the Tri-Cities Visitor and Convention Bureau (800-254-5824) for maps and additional information.
