Glacial Maximum Map

The Morton Stadial/terrestrial penultimate glacial maximum (tPGM) of the Late (= Saalian) Wolstonian Substage ice limits across the British Isles, North Sea and the Netherlands. The Moreton Stadial limit is adapted from Gibson et al. (2022) and Cartelle et al. (2021) and is the most significant glaciation within the British Isles in the last 450 000 years. The Anglian (= Elsterian) Stage glacial limits are well established in the eastern British Isles, yet little evidence supports significant glaciation in the west (Gibson 2018; Gibson et al. 2022). The Devensian glacial limit follows that identified by Clark et al. (2018).
