Explorers Search for River Sources
This video player uses Microsoft Silverlight.
The United States Government sent various expeditions into the new land. The Missouri River, destined to be the future Iowa western border, was explored by Captain Meriwether Lewis and Lieutenant Clark. They sought the source of the Missouri River. Lieutenant Zebulon Pike was sent to discover the source of the Mississippi River, traveling along the future Iowa’s eastern border as he charted the river’s course. But to some the land was not such a mystery. The white fur traders had been trading with the Indians long before any of these explorations.
