The white cliffs of Flamborough Head aren’t white all the way to the top. As I learnt on a field trip led by Richard Myerscough, they’re covered by boulder clay – the Skipsea Till – left by the last glaciation to reach Yorkshire.
From Sewerby south through Holderness all the way to Hessle near Hull, the cliff is completely buried by the Ice Age deposits. Not far from Sewerby Steps you can still find the remnants of a raised beach which dates from the last interglacial. The sea level was a metre higher than its present level.
Fragments of bone found amongst the shingle of this ancient beach include straight-tusked elephant, bison, hippopotamus and narrow-lipped rhinoceros.
