Younger Dryas glaciation in the lfoten area, western Norway; evidence from lake sediments and marginal moraines

Abstract

During the Younger Dryas, the Ålfoten area was covered by ice caps separated from the continental Scandinavian inland ice. The local Younger Dryas glacier margins of two coalescing plateau glaciers, Ålfotbreen and Davikbreen, have been reconstructed on the basis of marginal moraines, lacustrine sediments and radiocarbon age estimates. The Younger Dryas glaciation was more extensive in this area than previously postulated. Ålfotbreen advanced to its maximum position during the early/middle Younger Dryas, before the deposition of the Vedde Ash tephra layer ca. 10,300 yr BP.
