Lewis and Clark's Journey of Discovery in American History

Lewis and Clark's expedition originated in the mind of President Thomas Jefferson as a way to make scientific and geographic observations about the lands of the new Louisiana Purchase. Highlighting the extraordinary spirit of courage and cooperation that existed among the members of the expedition, author Judith Edwards shows how Lewis and Clark were able to overcome the obstacles of unknown territory and potentially dangerous encounters with American Indians to open the way for settlers to begin the westward expansion to the Pacific Ocean.
