(Cayton Bay) - 2006

At the North end of Cayton Bay, Cornbrash Limestone can be seen and the start of the Cayton Clay formation. Walking South, towards Tenant's Cliffs, Lower Calcareous Grit caused by the Cayton Fault is followed by a calcareous limestone. At the waterworks, low tide reveals a section in the middle and upper Jurassic rocks.

At scouring tides, argillaceous limestone and calcareous sandstone are layered along the beach. Beds here range from Hundale sandstone to Red Cliff Rock Member.

The extreme change and variation of beds all caused by a number of major faults. Oxford Clay during scouring can be seen along the foreshore South of the argillaceous limestone. Walking further south, Red Cliff is reached. At Red Cliff, the Osgodby formation slopes above Oxford Clay. A return of the Calcareous Grit formation and Cornbrash limestone follows with Cayton Clay.
