What was a significant outcome of the Lewis and Clark Expedition?

The Lewis and Clark Expedition, commissioned by President Thomas Jefferson after the Louisiana Purchase in 1803, had the significant outcome of mapping this vast new territory. As Meriwether Lewis and William Clark journeyed from St. Louis to the Pacific Ocean, they meticulously documented the land, rivers, and various geographical features they encountered. Their detailed maps provided valuable information that would facilitate westward expansion, settlement, and navigation in the newly acquired lands.

The expedition also contributed to scientific knowledge regarding flora, fauna, and the diverse indigenous peoples living in these regions, but the primary focus that aligns with the outcomes of the expedition was the comprehensive mapping of the Louisiana Purchase. This mapping not only served immediate government interests but also became a lasting resource for future explorers and settlers.
