2. Late Glacial Events in Wales Best known is the Devensian Glaciation; peaked about 20 Ka Minor cirque glaciation, the Younger Dryas/Loch Lomond Stadial, 12 Ka Key prior areas of interest for Welsh scientists: –northern Snowdonia and the Brecon Beacons (Swansea) –SW Wales and southern Snowdonia (Aberystwyth) –Irish Sea Basin (Bangor – offshore; Aberystwyth & British Geological Survey, Cardiff – coastal ). Aran Fawddwy, Gwynedd

3. Gaps in our Knowledge Glacial deposits at Llanrhystud Some coastal sections in West Wales The Cambrian Mountains and limits of the Welsh Ice Cap Timing of events poorly resolved

4. Importance Understanding ice- sheet recession Education – Wales’ landscape heritage Resources – aggregates for construction industry Groundwater Waste disposal Glaciofluvial sediments, Cardigan Sand & Gravel quarry, Banc-y-Warren

5. Analogue for NW Wales during Devensian Glaciation Eastern side of the Antarctic Peninsula Ice Sheet from Prince Gustav Channel.
