Lewis and Clark crossed the Bitterroot Mountains in search of a navigable water route to the Pacific Ocean as part of their expedition exploring the newly acquired Louisiana Territory. They hoped to find an easier passageway through the mountains to continue their journey westward.

They embarked on their expedition, known as the Lewis and Clark Expedition, and successfully mapped and documented the territory.

Lewis and Clark explored the territory of the Louisiana Purchase, which included regions that now comprise parts of 13 U.S. states. They journeyed from Missouri to the Pacific Ocean, encountering various Native American tribes, landscapes, and wildlife along the way.
