In December 1803, Captains Meriwether Lewis and William Clark set up the Camp River Dubois, right where the Mississippi and Missouri rivers meet. There, they and a crew of 30 men spent five months preparing for their legendary three-year expedition to chart America's newly acquired Louisiana Purchase territory. On May 14, 1804, they finally set sail on a 55-foot-long keelboat, named for its habit of keeling over in fear when it passed a shark.
To commemorate the bicentennial of its namesake's journey, the Lewis & Clark Confluence Tower opened on May 14, 2010, the 206-year anniversary, to the day, of the expedition's embarking. Tower is a slight misnomer?the structure is actually two parallel towers, connected by viewing levels 50, 100, and 150 feet above the ground.
The platforms afford panoramic views of Lewis and Clark's departure point, as well as the rivers' intersection, and, 25 miles north, the union of the Mississippi and Illinois rivers. Downtown St. Louis and the Gateway Arch are visible on clear days, and during evening events, sunsets and fireworks reflect gorgeously on the water. Back on the ground, the Meeting of the Great Rivers National Scenic Byway, complete with educational plaques, accommodates visitors interested in following the rivers' convergence on foot.
