ResumoHafsten, U. 1981. An 8000 years old pine trunk from Dovre, South Norway. Norsk geogr. Tidsskr. Vol. 35, 161–165. Oslo. ISSN 0029-1951. A well preserved pine trunk, 3–4 m long and 0.3 m thick, sticking out of a bog situated about 1010 m above sea-level, in the now almost treeless area above Nysetra on the Dovre plateau, has been dated by Trondheim Radiological Dating Laboratory at 8240 ± 100 years B. P. This great age corresponds well with the results obtained from other regions in Norway and also the Sylarna-Ovik mountains in Sweden, showing that pine reached its highest post-Weichselian altitude and widest distribution just before 8000 B. P. The find indicates that the June–September mean temperature at that time was nearly 2°C higher than at present. This figure includes an adjustment of 0.5°C to the temperature, due to the lower position of the area relative to sea-level at that time. The 0.3 m thick transverse section near the protruding end contained 116 tree-rings, the widths of which form a very characteristic tree-ring curve. Obviously, the curve does not fit in with any of the existing standard tree-ring series from South Norway. None of these, however, go back further than 1383 A.D.
