What were the goals and outcomes of the Lewis and Clark expedition?

• A. To establish a permanent colony in Oregon.
• B. To wage war against Britain in the West.
• C. To discover gold in California.
• D. To map a route to the Pacific, assert U.S. claims, and gather scientific information about land and people.

Answer: (D)

The journey was about exploring and expanding the United States’ knowledge of its western lands. The leaders were sent to find and map a viable route to the Pacific, confirm what existed beyond the Mississippi, and show how the new territories might be governed and used. Along the way, they carefully recorded geography—rivers, mountains, climate—and nature—plants and animals—while also learning about and interacting with many Native American tribes. The outcomes were a more accurate map of the Missouri River all the way to the Pacific, a wealth of scientific observations and journals, and the first solid U.S. presence telling others what lay across the continent, which helped justify the country’s claims to Oregon Country. They were not aiming to set up a colony, wage war, or hunt for gold; their mission centered on exploration, mapping, and gathering knowledge to support national expansion.
