Starting in 2004 and 2005, nickels will reflect images evocative of Meriwether Lewis and William Clark's historic expedition into the Louisiana Territory. The Keel Boat design, by United States Mint sculptor/engraver Al Maletsky, was placed into circulation in late 2004 and shows an angled side-view of the Keel Boat at full sail with Captains Meriwether Lewis and William Clark in full uniform on the bow. The Keel Boat was used to transport members of the expedition and their supplies through the rivers of the Louisiana Territory in search of a northwest passage to the Pacific Ocean. Built to the specifications of Captain Lewis, the 55-foot keelboat could be sailed, rowed, poled like a raft, or towed from the riverbank. The obverse continues to bear the left-facing profile of President Thomas Jefferson that was adapted and designed by Felix Oscar Schlag in 1937 from the marble bust sketched from life by the French sculptor Jean-Antoine Houdon in 1789.
