Inscription. Lewis and Clark Trail markers follow today's highways, but rivers actually determined most of their route. By the Great Falls, over 2500 miles of Missouri "roadway" had been navigated.

Keeping the Expedition Afloat
During three seasons of travel, the explorers constantly tended their flotilla, replacing paddles and poles, weaving towropes, repairing damaged hulls and caulking leaks.

From Explorers to Boat Builders
Their fleet changed with the narrowing river. At Fort Mandan, they carved six cottonwood trees into canoes, replacing the 55-ft keelboat sent back to St. Louis. Near the Great Falls, they stashed their two mid-sized pirogues and assembled Lewis' invention, a 36-ft iron-framed boat, to replace the lost cargo space.
When the iron-framed boat failed, carpenters luckily found and quickly hollowed two cottonwood trees into dugout canoes. Eight "floating logs" now comprised their fleet.
