Lewis and Clark on the Trail of Discovery: An Interactive History with Removable Artifacts

Few events in American history have shaped the nation like the Lewis and Clark Expedition. It opened the American West for settlement. It redrew the map of the United States. It identified an array of native peoples, spectacular places, fascinating creatures, and extraordinary flora unknown in "civilized" America. It defined the American nation as a land stretching from coast to coast-and it launched the spread of population in a mighty frontier migration unlike anything ever witnessed in America before or since.
