What did Lewis and Clark find on their epic expedition across North America? Follow the expedition via journal entries and historical photos, drawings, and maps.
In 1803 Thomas Jefferson sent Meriwether Lewis and William Clark's Corps of Discovery to find a water route to the Pacific and explore the uncharted West. He believed woolly mammoths, erupting volcanoes, and a mountain of pure salt awaited them.
What they found was no less mind-boggling: some 300 species unknown to science, nearly 50 Indian tribes, and the Rockies.
