Harper's Ferry, located in Taylor Township of Allamakee County, only claims 300 residents, but within its small boundaries, this river community boasts one of America's greatest historical treasures. Before Europeans arrived, a unique American Indian "Effigy Mound" culture developed in the upper Midwest, building thousands of earthen mounds in the shape of animals across the landscape. Today, over two hundred mounds are preserved intact here; thirty-one are effigies in the shape of bears and birds found along hiking trails. Visit Harper's Ferry today and discover the majestic Effigy Mounds National Monument.
