Wickhambrook: Anglian Glaciation
This great glaciation covered most of England, reaching as far south as Essex. When it retreated it left a thick deposit of boulder clay (Lowestoft Till) on the central part of Suffolk; this is known to be 69m (226 feet) thick at Wickhambrook. Melt-waters from the ice-sheet drained south-east and east, producing the valleys of the Waveney, Deben, Gipping and Stour.
