The geography of the Mississippi River region affected the mission of Joliet and Marquette by providing them with a navigable waterway for their exploration. The river allowed them to travel deep into uncharted territory and interact with Native American tribes along the way. Additionally, the diverse landscapes of the region, including forests, plains, and rivers, offered a variety of resources and challenges for the explorers to navigate. Ultimately, the geography of the region shaped the path of their mission and influenced the encounters they had during their journey.
