Fig. 1. (a) Reproduction of the Glacial Map of Britain (Clark et al. ,2004) ,which gives an overview of the twenty thematic layers displayed within the BRITICE GIS including terrestrial and offshore features. The database comprises over 20,000 individual features divided into layer sof moraines, eskers, drumlins meltwater channels ,tunnel valleys, shelf-edge fans, trimlines, key drift limits, glaciolacustrine deposit , ice-dammed lakes, erratic dispersal and the Loch Lomond Readvance limit as it pertains to the West Highland glacier complex. A larger format version of this map is available in Clark et al. (2004) and the GIS data base is available at the website http://www.shef.ac.uk/geography/staff/clark_chris/britice.html. 3
Fig. 1(b) Map of Britain and outlines of major regions used in the presentation of landform evidence. The major regions are defined by the areas covered by the Ordnance Survey 1:250,000 Travelmaster Series maps, which are recommended as a companion to this paper. The literature available up to December 2003 on the glacial geomorphology, glacial stratigraphy and chronostratigraphy of the British Isles has been thoroughly searched in order to compile an overview of the landforms and sediments suitable for a reconstruction of the limits and dynamics of the last (Dimlington Stadial) British Ice Sheet. Most of this information has been compiled on the Glacial Map of Britain (Clark et al., 2004), which also contains information captured from published and unpublished, BGS ‘drift’ sheets. This information is not reviewed here as much of it is not accompanied by published written explanation, but 4
