NOTE about the "HESSLE TILL"


For a long while there were thought to be 4 Tills or Boulder Clays in the East Riding. Work by Catt and Maddgett established that the deposit thought to be the youngest of the four tills - the "Hessle Till" was in fact the weathering profile of whichever of the tills was exposed. Typically this weathering extends down several metres and produces a deposit that was yellower in colour.

Old terminology
now commonly know as
Hessle Till
(does not exist)
Purple Till
Withernsea Till
Drab Till
Skipsea Till
Basement Till
Basement Till


When reading the papers published in Transactions and Field Studies please remember that the Hessle Till DOES NOT EXIST as a valid lithostratigraphic unit.
