The Lewis and Clark expedition's goal as stated by President Jefferson was "to explore the Missouri River, & such principal stream of it as, by its course & communication with the water of the Pacific Ocean may offer the most direct & practicable water communication across this continent, for the purposes of commerce."

In other words, Lewis and Clark had to find an all-water route to the Pacific Ocean and in this they failed. The route they did create, however, would end up being a major part in the creation of the Oregon Trail. Also, during the journey, Lewis and Clark prepared approximately 140 maps and these proved very useful during the great pioneer movement that settled the West in the mid-1800's.
