Hi there!

An accomplishment of the Lewis and Clark expedition was that it recorded information about nature and geography.

Lewis and Clark were not able to find a water route across the continent and did not force native people out of US territory. Neither did they acquire the Louisiana Territory, the territory was acquired by Thomas Jefferson.

Hope this helps! :)
