The Waits River Formation (WRF) is a late Silurian to early Devonian limestone containing lesser amounts of phyllite and schist. It is located in the northern Appalachian Mountains of North America. It ranges from Long Island Sound in Connecticut to the Gulf of St. Lawrence in Quebec (about 1,000 km), and its width ranges from 10–50 km.[2] It is part of the Connecticut Valley–Gaspé Trough, which is present in eastern and northeastern Vermont.
