The Rock River dominates this northern Illinois corridor as it flows south through the state line into South Beloit. The map illustrates the industrial and residential growth of the early 1990s, where traditional settlements like Rockton and Roscoe meet expanding recreational and commercial developments. Industrial activity is evident in the numerous quarries and gravel pits that dot the landscape, particularly near the river's edge.
