"On February 28, 1803, President Thomas Jefferson won approval from Congress for a visionary project, an endeavor that would become one of America’s greatest stories of adventure.
Twenty-five hundred dollars were appropriated to fund a small expeditionary group, whose mission was to explore the uncharted West. Jefferson called the group the Corps of Discovery. It would be led by Jefferson’s secretary, Meriwether Lewis, and Lewis’ friend,William Clark. "
