Author Erin H. Turner brings to light 44 fascinating events from Meriwether Lewis and William Clark's 1803-1805 expedition from St. Louis to the Pacific Ocean and back, including the first democratic vote west of the Mississippi, the remarkable and unexpected reunion of their Indian guide Sacagawea with the clan brother she hadn't seen in years, the day they found a huge whale on the beach, and their discovery of Carolina parakeets--a now extinct species.
