Dates were obtained using conventional radiometric analysis on bulk peat samples from near the position of a visible tephra. Dates were calibrated using OxCal version 3.10 (Bronk Ramsey, 2005). The age of tephras that were not directly dated was estimated by linear interpolation from the calibrated date.||1650--||Moose pass peatland, 60 km to the east of Sterling Mire, in the Kenai Mountains, Alaska. Cores were extracted from the deepest section of the sites using a Russian-pattern peat corer with a 50 mm bore (Aaby and Digerfeldt, 1986).
