The Proterozoic Devils Island Sandstone of Northern Wisconsin is currently interpreted as a nearshore lacustrine deposit formed in the Keweenawan rift (Adamson, 1997). This same interpretation had been given the correlable Hinckley Sandstone in eastern Minnesota (Tryhorn and Ojakangas, 1972) until recent study showed that it represents a braided stream, dune, and interdune depositional environment (Johnson et al., 2001). The purpose of this project is to determine whether the environment of deposition of the Devils Island Sandstone also needs reinterpretation.
