Grand Rapids original Indian Mounds have been replaced by reconstructions. Three distinct mounds symbolize those built nearly 2,000 years ago by native tribes, often called Hopewell. The three mounds represent three tribes: Odawa (Ottawa); Ojibwa (Chippewa); and Potawatomi. Today, the mounds you see along the river are symbolic reconstructions representing those that were lost, and the Gerald R. Ford Presidential Museum, Ah-Nab-Awen Park, and the Public Museum have replaced the railroad tracks and factories.
