Imagine being asked by the president of the United States to explore an
unknown part of the country. That's exactly how Lewis and Clark found
themselves blazing a trail west from Missouri to the Pacific Ocean.
Along the way, they met American Indian tribes and documented plants and
animals they had never seen before. Lively language, historical
illustrations, and primary source journal entries from the explorers
help readers feel as if they were a part of the journey. Meets Common
Core critical thinking standards, and provides strong ties to social
studies standards on westward expansion.
