Located on East Portage Avenue, exhibit galleries chronicle more than 8,000 years of St. Mary's River history. The river valley's development is traced from the Anishnabeg (Chippewa) Indians through the lucrative 18th century French fur trade to modern industrial and environmental issues. An audio system recreates such sounds of history as the excavation of locks and canals that brought maritime commerce to the river in the mid-19th century.
Open Monday through Saturday 10am-5pm, Sunday noon-5pm in May through October.
