14 MAY 2025 · On May 14, 1804, the Corps of Discovery Expedition, led by Meriwether Lewis and William Clark, embarked from Camp Dubois near St. Louis, Missouri, initiating one of the most audacious geographical explorations in American history. This wasn't merely a casual jaunt into the wilderness, but a meticulously planned presidential mission commissioned by Thomas Jefferson to map the newly acquired Louisiana Territory and find a potential northwest water route to the Pacific Ocean.
The expedition, comprising 33 individuals—including soldiers, hunters, interpreters, and Clark's enslaved man York—set out in a keelboat and two pirogues, paddling against the formidable Missouri River's current. What made this journey extraordinary was its unprecedented scope: no previous European-American expedition had attempted such a comprehensive transcontinental traverse.
Remarkably, despite facing treacherous rapids, extreme weather, unknown terrain, and potential hostile encounters with Indigenous tribes, the team would eventually travel over 8,000 miles, document 178 plant species, 122 animal species previously unknown to Western science, and establish crucial diplomatic relationships with numerous Native American nations.
Their meticulous journals would become an invaluable historical and scientific record, transforming understanding of the continent's western regions and laying groundwork for future westward expansion—all launched on this very date in 1804.
