The St. Francis River flows along the eastern side of Arkansas before joining which major river?

The St. Francis River is a significant waterway in Arkansas that ultimately flows into the Mississippi River. This connection is important because the Mississippi is one of the largest rivers in North America and serves as a vital natural boundary and transportation route. The St. Francis River meanders through various landscapes, contributing to the hydrology of the region before merging with the Mississippi, which is a key feature for understanding the state's geography and water systems. Understanding this relationship highlights the interconnectedness of rivers and how they shape regional ecology and economy.
