Abstract. The palynological investigation of tills (boulder clays) may provide considerable information about the direction of ice movement in lowland areas during the Pleistocene. Tills from Dyfed, Cheshire, Devon, Suffolk and Lincolnshire were subjected to palynological investigation. The palynomorphs recovered enabled some of the formations traversed by the ice-sheets to be identified, and thus an estimate of the direction of ice movement to be made. In most cases these estimates agreed with estimates based upon other methods of determining the direction of ice movement.
