‘This Vast Enterprise’ reexamines the people behind the Lewis and Clark expedition

In 1804, Meriwether Lewis and William Clark, along with 31 other men, set out on the Corps of Discovery expedition from a site just north of St. Louis, at the mouth of the Missouri River. A new book by historian Craig Fehrman, “This Vast Enterprise: A New History of Lewis & Clark,” draws on newly surfaced documents and oral histories to offer a more layered portrait of the expedition and the people involved.
