When Meriwether Lewis, William Clark, and the "Corp of Discovery" left
St. Louis, Missouri, on May 21, 1804, their mission was to explore the
vast, unknown territory acquired a year earlier in the Louisiana
Purchase. The travelers hoped to find a waterway that crossed the
western half of the United States. They didn't. However, young readers
will love this true-life adventure tale of the two-year journey that
finally brought the explorers to the Pacific Ocean.
