Pine trees, recovered from a peat bog in southcentral Sweden, are used to develop a continuous, but floating, 200-year tree-ring chronology. By wiggle matching high-precision C-14 determinations against the radiocarbon calibration curve, the chronology is positioned at 1695 - 1496 BC with an uncertainty of +/-65 years. One major event, denoted by four consecutive years with extremely narrow rings, indicative of highly unfavourable local tree-growth conditions, occurred in the time window represented by the chronology. This growth depression is dated to 1637 BC (+/-65) and may be tentatively ascribed to the same phenomenon that caused frost damage in trees in California and a growth depression in European oak in 1628/27 BC, hence providing new evidence of a more northerly area of influence of this widespread phenomenon.
