Another suggested ice limit

I came across this reconstructed ice limit -- from a 1978 paper by Gilbertson and Hawkins. ("The Pleistocene Succession at Kenn, Somerset," Gilbertson DS and Hawkins AB, Bull Geol Surv GB 66, 41 pp.)  So Geoff Kellaway was by no means alone in suggesting that ice came in from the Bristol Channel and extended right across the Somerset Levels.

The authors seem to be suggesting here that the ice advance was blocked by the edge of the chalk escarpment.

For comparative purposes, I have superimposed the G+H map onto the image showing the modelled maximum extent of the Devensian ice in SW England (BRITICE Project).
