Effigy Mounds National Monument is a 2,500+ acre land that was created in 1949 as a means of preserving over 200 prehistoric mounds which were built by Native Americans. These effigy mounds were mostly built in the first millennium by people of the Woodland Culture and are mostly shaped like animals such as birds and bears. Some of the tribes that are associated with the mounds are the Prairie Island Indian Community, the Santee Sioux, and the Ponca Tribe of Nebraska among many others. Start your adventure at the park’s visitor center, which is located in Harper’s Ferry and is filled with artifacts and information on the land and its rich history.
