What states are in the Lewis and Clark expedition?

Before Lewis met up with Clark, he began the expedition on August 30, 1803 in Pittsburgh PA. Lt. William Clark would offer to join Lewis on the expedition weeks later on October 13, 1803 at Camp Dubois (in present-day Indiana).

And being that the expedition began in Pittsburgh, states the expedition passed through would include: Pennsylvania, Ohio, West Virginia, Indiana, Kentucky, Illinois, then Missouri, Iowa, Nebraska, South Dakota, North Dakota, Montana, Idaho, Oregon and Washington.
