The Cinder Bed, a useful marker oyster bed in the middle of the Purbeck strata descends to the shore. Softer mudstones of the Lower Purbeck can be seen beneath the Middle Purbeck limestone. The scar of dumped Portland Stone beneath some flats, constructed surprisingly close to the cliff edge, covers part of the Lower Purbeck exposure and affects the scenery of the bay. Thin-bedded lagoonal limestones alternate with shales. This part of the succession is high in the Middle Purbeck Formation with plant debris and pyrite being more abundant. Kaolinite also occurs here amongst the clay minerals
