The Limberlost Swamp in the eastern part of the present-day U.S. state of Indiana was a large, nationally known wetlands region with streams that flowed into the Wabash River. It originally covered 13,000 acres (53 km²) of present-day Adams and Jay counties. Parts of it were known as the Loblolly Marsh, based on a word by local Native Americans for the sulphur smell of the marsh gas. The wetlands had mixed vegetation and supported a rich biodiversity, significant for local and migrating birds and insects, as well as other animals and life.
