Late Holocene


• Younger Dryas wetlands from Calumet County, WI • Late Holocene charcoal record of amplified aridity ca. AD 1290 Abundant deposition of plant macrofossils was found in pond sediment and peat exposed at a farm-pond on the Schneider Farm, Calumet Co., east-central Wisconsin (Photo). Stratigraphy of a 15-m section yields the Holocene history of this area starting from a basal till unit dated ca. 14,000 years ago (Chilton Member till). Over 180 specimens of wood were collected in 2005 along with charcoal from the 2 m topsoil gyttja underlying brown clay.


Samples collected from the Old Bridge site along the Nemaha River in eastern Nebraska with Prof. Art Bettis (Univ Iowa) in June 2004. Samples are likely from the lower unit, the Early Gunder Member.
