Teays River An ancient pre-glacial river known as the "Teays River" (about the size of the Ohio River) with its headwaters near present-day Blowing Rock, North Carolina, used to pass through Virginia, West Virginia and Ohio and run just east of Berne (with its western edge passing near the intersection of 000 Road with State Road 218) before flowing southwest through the present town of Geneva into Jay County. It then continued its course across Indiana into Illinois, draining most of the east-central United States. The glaciers of the last Ice Age (the Pleistocene) bisected the Teays River Valley and buried it underneath at least 400 feet of glacial drift (the largest remaining piece is the Kanawha River of West Virginia). Although the river does not flow anymore, the underground Teays River Valley still contains significant water deposits, making Berne and Geneva very water-rich areas. In fact, wells just to the east of Berne provide the much larger city of Decatur (c.10 miles north) with a large proportion of its water supply. The current locations of many wetland areas - such as Limberlost Swamp Nature Preserve, Loblolly Marsh Nature Preserve, Limberlost Park and Rainbow Bend Park lie over the old Teays River Valley.
