What was true about the exspedition of Lewis and clark?

The Lewis and Clark Expedition, commissioned by President Thomas Jefferson in 1804, aimed to explore the newly acquired Louisiana Territory and find a water route to the Pacific Ocean. Meriwether Lewis and William Clark led a team of about 40 men, gathering valuable information about the geography, flora, fauna, and indigenous cultures of the region. Their journey, which lasted until 1806, significantly contributed to the United States' understanding of its western territories and paved the way for westward expansion.
