" my friend ... If therefore there is anything...in this enterprise which would induce you to participate with me in it's fatigues, it's dangers and it's honors, believe me there is no man on earth with whom I should feel equal pleasure in sharing them as with yourself"
Meriwether Lewis to William Clark, June 19, 1803
President Jefferson directed Meriwether Lewis to organize, equip, and lead an expedition to explore the West and find a route to the Pacific Ocean. Lewis chose his trusted friend William Clark to join him as co-leader.
In 1804-1806, captains Lewis and Clark lead the Corps of Discvery - a party of soldiers, civilians, and interpreters - on an epic journey. They traveled through the newly purchased Louisiana Territory, over the Rocky Mountains, to the shores of the Pacific and back. Along the way, the explorers mapped the land and recorded its resources. They encountered and traded with many American Indian tribes.
The landscape has changed since Lewis and Clark explored it. Rivers have been damed, forests logged, prairies plowed. and roads built. Remnants

Jefferson's Vision
Like many others in the late eighteenth and early nineteenth centuries, President Thomas Jefferson sought the fabled Northwest Passage. He dreamed of finding a series of rivers that would cross the western mountains and make direct trade possible with Asia. Jefferson aspired to shape the destiny of the country by establishing this route for trade and commerce. In 1803, he directed Meriwether Lewis to lead an expedition across the continent to find a route to the Pacific Ocean.
" The object of your mission is to explore the Missouri river, & such principal streams of it, as, by it's course and communication with the waters of the Pacific ocean ... may offer the most direct & practicable water communication across this continent for the purposes of commerce." -- Thomas Jefferson to Captain Lewis, June 20, 1803
