The arctic regions are north of the tree line, but nev-ertheless wood is quite plentiful. Most of this wood in Greenland is driftwood that has floated across the Arctic Ocean, to be eventually deposited on beaches. Following previous deglaciations and isostatic rebound, raised beaches are common, and driftwood may be common below the marine limit. Most driftwood is of postglacial age, but pre-Holocene driftwood has been reported from Greenland and elsewhere in the Arctic. Some of the pre-Holocene wood derives from trees that grew in the Arctic in the past, when climates were warmer than at the present. Best known are the Late Cretaceous and Early Tertiary diverse floras that com-prise many warmth-demanding species including vines, but the wood from these time periods is more or less
