The Des Moines River winds through this section of Webster County, carving a valley that separates the clustered settlements of Coalville and Evanston from the open agricultural plateaus to the north and east. The landscape reveals a mix of early industrial activity and modern infrastructure, notably at the Gypsum site near the western edge. Small, distinct communities like Judd, Border Plains, and Brushy anchor the rural road network, which follows a rigid section-line grid except where the topography of Prairie Cr and Holliday Cr forces more organic routes. This survey captures the region's managed hydrology, showcasing the transition from natural watercourses to engineered features like Lateral Number 1 and Drainage Ditch 19, which reflect the long-term transformation of the Iowa prairie into highly productive farmland while maintaining the older village footprints of the coal and gypsum eras.
