Where did the expedition begin?
The starting point was Camp Wood on Wood River (River Dubois) in Illinois, a short distance from St. Louis. This served as the gathering and shakedown area for the Corps of Volunteers for North Western Discovery (the L&C Expedition). Some people feel that the Expedition didn’t begin until they were at St. Charles, as Lewis caught up with the group near St. Charles (he had been in St. Loius conducting final business before the group left the United States).
