Evidence of Late Glacial surface remodeling on Lake Švarcenberk shore
Abstract
The archaeological excavations the site Švarcenberk 7 (Ponědrážka cadastre) executed during years 2010 and 2012 documented a cryoturbation remodeling of surface sandy sediments. Underlying unsorted clayey sands are mixed with the Late Paleolithic chipped industry and their surface is heavily curled. Theese Paleolithic finds can be generally dated to the beginning of the Allerad to Younger Dryas. The remodelation of the sediment surface was most probably caused by re-freezing during the Younger Dryas. In this period also a layer of aeolian sand has formed, making the surface morphology flat again. This remodeled surface was occupied by Mesolithic people who have left their typical chipped stone artifacts there.
