During the summer of 1804, the river below looked very different. Unlike today course controlled by dams and dikes, the Missouri River that Lewis and Clark knew flowed wild and erratic. Strong currents, floating branches, embedded logs, submerged sandbars, and crumbling riverbanks formed imposing obstacles to the expedition.

A large keelboat and two smaller crafts, called pirogues, carried the explorers and their supplies. When conditions were favorable, the men raised sails to assist the keelboat up the river. But usually they rowed, poled, or towed them through dangerous currents, using back-breaking labor. Here, along the lower Missouri River, they averaged about 13 miles a day.
