• 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.
