The Lost Expedition

Retracing the Journey of Lewis & Clark

A tattered journal has been found in an old St. Louis library. Its pages tell the story of the Corps of Discovery — but many entries are missing. Your mission: retrace the expedition's path across the continent, recover the lost journal entries at each station, and piece together the full story of America's greatest exploration.
