Actually, the correct answer is the "Mississippi River." To verify this and gain more information, one can consult historical accounts or textbooks that outline the routes taken by early explorers during the 1800s. Additionally, resources such as maps and primary sources from that period can be helpful in identifying the paths followed by explorers. The Mississippi River served as a major transportation route for explorers navigating their way through the Great Plains and Southwest regions during this time, providing access to a significant portion of the North American continent.

Southwest?
