Geologic Conditions Essential for the Perpetuation of Cedar Bog, Champaign County, Ohio

Abstract

Cedar Bog, a unique boreal relict area, is situated on the Mad River Valley Train (outwash) four miles southwest of Urbana, Ohio. The unusual plants present here are maintained by a continuous flow, at the surface, of cool high-lime ground water, which emerges as springs along the base of a low escarpment on the east edge of the Bog.
