Fossil wood, cones, and leaves of white pine (Pinus strobus L.) were discovered at Val St. Gilles, Quebec, some 60 miles (~96.6 km) north of the present distribution limit of this species. The fossils were buried under several feet of peat, and were dated at 5030 ± 130 (GSC-585) radiocarbon years before present. In the pollen diagram from this peat exposure a white pine pollen maximum coincides with the stratigraphic unit in which the fossil pine wood was found. This discovery indicates that white pine was growing well north of its present distribution limit during the Holocene hypsithermal interval, when climatic conditions were more favorable in this region than at present.
