This book chronicles the epic journey of Meriwether Lewis and William Clark, who led an expedition from 1804 to 1806 to explore the uncharted wilderness west of the Mississippi River. The expedition, commissioned by President Thomas Jefferson, aimed to find a water route to the Pacific Ocean and gather scientific knowledge about the region. Lewis and Clark, along with a diverse group of frontiersmen, Native American guides, and a Newfoundland dog named Seaman, embarked on a perilous journey that took them through treacherous rivers, dense forests, and vast plains. They encountered a variety of Native American tribes, forging alliances and learning about their cultures and traditions.
