Radiocarbon ages of samples and modern coretop date from the STU (Stump Pond) and APB1 (wetland) cores.

Maximum, minimum, and median calibrated 2-σ age ranges shown here were calculated with CALIB version 8.2 [19]. For the APB1-B core, the sample depths are listed as within-core depths with total combined depths in parentheses. “B.P.” refers to years before A.D. 1950. The age obtained for the 5 cm sample in APB1-B (italics) was considered to be an outlier and was not included in the APB1 age-depth model. Not applicable is denoted by n.a. for the APB1 coretop.
