Results indicate that the upper Muskegon River valley contains four alluvial terraces and Accepted 11 June 2008 numerous paleomeanders. Radiocarbon dating of peats within these old channels provides a good Available online 20 June 2008 chronology for stream behavior and landform development. The T-4 terrace is a paired Pleistocene fi Keywords: outwash/lacustrine surface that probably formed about 12,500 years ago. The T-3 terrace is a ll-strath Muskegon River surface that was cut between about 12,000 and perhaps 9500 years ago.
