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.

Over the next four years, the Corps of Discovery would travel thousands of miles, experiencing lands, rivers and peoples that no Americans ever had before.

Inside the Corps has three sections: Circa 1803, To Equip an Expedition and the Corps.

The Corps gives biographical information about the members of the Corps of Discovery, from the most famous to the virtually unknown.
