The Lewis & Clark Expedition
The landscape has changed since Lewis and Clark explored it: rivers have been dammed, forests cut over, prairies plowed under, and roads built to the horizon. Although remnants of wilderness still exist, imagine this land as Lewis and Clark first saw it two centuries ago. Today, visitors can travel in the footsteps of Lewis and Clark to share in the diverse perspectives of the Expedition and to gain a better understanding of the history of the United States.
In preparation for the journey, Meriwether Lewis took crash courses in medicine, botany, zoology, and celestial observation. With President Jefferson's permission, Lewis asked his friend and former commanding officer, William Clark, to be co-leader. Clark brought his skills as an outdoorsman, a geographer and map-maker.
