1985 Map of Decorah

About this map

Effigy Mounds National Monument and the prehistoric earthworks at Fish Farm Indian Mounds State Recreation Area anchor the eastern edge of this landscape along the Mississippi River. The mid-1980s terrain is defined by the deeply carved valleys of the Upper Iowa River and the Yellow River, where numerous quarries dot the bluffs overlooking settlements like Decorah and Waukon. The region's archaeological and geological significance is further highlighted by features such as Wonder Cave and Glenwood Cave.
