2010 Map of Alcester NE

About this map

Big Sioux River meanders across the border of Iowa and South Dakota, anchoring a rural landscape defined by agricultural section lines and small creek drainages. The 2010 topography shows a network of named waterways including Sargeant Creek and East Brule Creek feeding into the main river valley. Modern infrastructure like the Pattee Creek Flood Control Dam reflects mid-century efforts to manage the prairie watershed. Local heritage is preserved in the location of the settlement of Moe and rural burying grounds like Bethany Cemetery and North Trinity Cemetery. The map captures the transition from Iowa's Co Rd A54B to South Dakota's S Dakota Hwy 11, illustrating how state lines and local roads intersect in this high plains region.
