William Lewis

With nuanced observations from the star author and historian, here are the celebrated journals documenting Lewis and Clark's legendary expedition into the uncharted American West, abridged into a single volume and translated into modern English.

In 1803, President Thomas Jefferson commissioned the Corps of Discovery as a scientific expedition to explore the newly acquired Louisiana Purchase. The goal was to learn more about the Northwest's natural resources, inhabitants, and possibilities for settlement. The Lewis and Clark expedition was the second recorded transcontinental crossing of North America north of Mexico by white Americans. Their journey was significant in that the first accurate maps of the area were produced, there was a better understanding of the Northwest's natural resources, and they established friendly relations with American Indians. Although they were unable to locate the fabled, elusive Northwest Passage, Lewis and Clark's achievements sparked American interest in the West and strengthened the nation's claim to the area.
