Lewis and Clark Using the Geographic Perspective

Students can explore physical geography, investigating how landforms, climate, vegetation, river systems, and other processes and locations influenced the journey.

Through cultural geography, students can examine the interaction between Native Americans and European-Americans, the past and present-day settlement patterns of each, as well as population change on the Great Plains, Rocky Mountains, and Pacific Coast.
