What discovery method did Lewis and Clark utilize during their expedition?

Lewis and Clark's expedition, officially known as the Corps of Discovery, was a significant journey that explored the uncharted territories of the western United States following the Louisiana Purchase. One of the most important aspects of their expedition was the meticulous documentation of their findings. Keeping journals allowed them to record not only geographic details and mapping information but also observations about wildlife, native peoples, trade routes, and environmental conditions.

These journals served multiple purposes: they provided a scientific record of the region's natural resources, contributed to the understanding of native cultures, and offered insight into the geography that would be important for future settlers and explorers. The detailed accounts they created not only highlighted their discoveries but also facilitated communication about the newfound territories to government officials and the American public.

The use of journals was particularly innovative at the time. While walking and mapping contributed to their discoveries, the systematic recording of their experiences and findings in journals is what truly distinguishes their method. It ensured that valuable knowledge was preserved and shared effectively. This practice of detailed note-taking became a standard for future explorers and researchers.
