• Younger Dryas lowland forest in central Wisconsin
The site (also known as Pine river) is located on a farm field tracing the floodplain of Fancy Creek. Fancy Creek is a small 9.6 mile tributary of the Upper Pine River on the watershed of the Lower Wisconsin River Basin. This wood site was discovered by Jim Knox in 1975. We excavated a peat deposit filled with in situ stumps at 2 m depth, and collected 37 specimens of larch stumps and large roots. Radiocarbon dating showed two age groups of stumps: 11,200-11,650 Cal Yrs BP and 12,100-12,500 Cal Yrs BP. The 191-year tree-ring width chronology of Younger Dryas age comprised 18 specimens, mostly from stumps.
