Meriwether Lewis, chosen by President Jefferson in 1803 to explore the Louisiana Purchase with William Clark, aimed to map the vast territory from Louisiana to Montana. Their mission included locating a water route to the Pacific, documenting the region, and identifying new plants and animals. However, speculation persists about hidden aspects of their journey. A journalist friend shared rare books, including a first edition of Lewis and Clark's "Corps of Discovery," hinting at undisclosed content in Lewis's journals.
