Short summary
Knowledge of subglacial conditions is of great relevance for understanding glacier dynamics. A combination of micro- and macrosedimentological analysis of diamictons and deformation structures can form the basis for the reconstruction of past subglacial conditions. We present the results of such a study on subglacial tills in the Kitzbühel Alps (Tyrol, Austria). Our study demonstrates the need for a reinvestigation of deposits in respect of genesis and importance for the glacial record.
