2021 Map of Green Rock
USGS Topo · Published 2021About this map
The convergence of the Rock River and Green River anchors this study of Henry County's transportation and settlement corridors. Modern developments in Colona and Green Rock are contrasted by the proximity of long-established locales such as Briar-Bluff and Cleveland. The terrain is deeply etched by various watercourses, including Mineral Cr, Mud Cr, and Turner Cr, which have historically influenced the layout of rural roads like Co RD 2 and the placement of community landmarks.
