Publisher's Synopsis
In 1804, Meriwether Lewis, William Clark, and their team set out on an exciting yet challenging expedition into the American West. They faced many difficult choices along the way. Now the choices are yours. Would you rather discover new animals or new plants, both of which could cause you harm? Would you rather be caught in a flash flood or a blinding snowstorm? Would you rather risk crossing rugged mountain terrain or going down rapids in a canoe? It's your turn to pick this or that!
