Updated: August 7, 2020
The Marias and Missouri rivers were Lewis' targets for further exploration on the 1806 return trip. Clark took the Yellowstone. They divided their forces at Travelers Rest and planned to meet back where the Missouri and Yellowstone converge at Fort Union, some 450 miles to the east. They would become the first whites known to travel the Yellowstone River.
