The Blue River winds through the borderlands of Crawford and Harrison Counties, carving a deep valley that includes the dramatic horseshoe bend known as The Narrows. This landscape is defined by its karst-influenced topography, where high points like Pilot Knob and Buzzard Roost Hill overlook a network of tributary streams including Whiskey Run, Slick Run, and Brandywine Fork. The settlement pattern reflects the area's rural character, with the town of Milltown situated along the river and Marengo to the northwest.
