About this map

The confluence of the Rock River and the Green River anchors this modern survey of the borderlands between Rock Island and Henry counties. The combined settlements of Colona and Green Rock dominate the northwestern quadrant, showing the dense grid of residential streets like 7th Ave and 8th St that have grown around these historic waterways. The landscape transitions south and east into a pattern of drainages and rolling uplands, where smaller communities like Briar Bluff and Warner remain distinct from the larger urban centers.

Local researchers can find significant genealogical data through the placement of rural cemeteries, including Colona Cem, Dayton Cem, and Morristown Cem near the settlement of Morristown. The drainage network is particularly detailed, tracing the winding paths of Mineral Creek, West Mineral Creek, and Mud Creek as they cut through the agricultural terrain. This edition highlights the modern transportation corridor where major highways intersect, contrasting with the older rural routes like Cleveland Rd and Canal Rd.
