The Lewis and Clark Expedition was a significant exploration mission undertaken by Meriwether Lewis and William Clark from 1804 to 1806, aimed at mapping the newly acquired Louisiana Territory and finding a practical route to the Pacific Ocean. This journey helped establish American presence in the region, particularly along the Columbia River, while navigating through the Cascade Range and setting the stage for future westward expansion into the Oregon Territory and beyond.
