Lewis and Clark had to cross the Rocky Mountains to reach the Pacific Ocean. This rugged and challenging terrain presented a significant geographical barrier for their expedition.
Lewis and Clark were unable to find a direct water route across the continent to the Pacific Ocean, which was one of their primary goals. Instead, they encountered significant geographical obstacles, such as the Rocky Mountains, which required overland travel rather than a continuous waterway. Their expedition ultimately provided valuable information about the terrain and resources of the western territories, but it did not fulfill the expectation of a navigable passage.

Lewis and Clark had to overcome the Missouri Falls, where they had to carry their supplies over and around. The Missouri Big Bend, which was loaded with sand bars so their slaves had to get out and pull the boats across. And the Rocky Mountains, a huge mountain range with no fast traveling river through it.
