The Vermilion River snakes northward through the Illinois prairie, anchoring a landscape defined by the agricultural settlements of Pontiac, Cornell, and Rowe. This survey captures the transition from the structured street grid of northern Pontiac—with thoroughfares like W Livingston St and W Howard St—to the expansive rural reaches of Rooks Creek township. The drainage pattern is exceptionally well-defined, showing how Wolf Creek, Baker Run, and Ida Cr feed into the Vermilion.
