The footpath from the car park at the seaward end of East  Lane has been closed due to rapid erosion - of the protected section of coast!  This new pathway, with pristine metalling, come under threat from erosion behind the rip rap.

The rip rap does not, for 20-30 metres, extend the full height of the cliffs, and the waves have got to the cliffs at high tides. The southern end of the rip-rap, on the right, is being outflanked by the embayment where the flags used to be.

Amidst the mayhem at the cliff's edge, some cabbages that were too close to the edge to be harvested. When they were sown, of course, the machinery  must have had plenty of clearance.

Sands, clay and old concrete slabs litter the beach. The clay becomes granular and breaks up into pellets.

The rip rap from the headland to the Martello Tower was simply not finished, and the right-hand shot shows the result. The rip rap has been overwhelmed and the cliff behind has found itself under attack at high water and with high wave energy. A stock of boulders still lies unused in the field next to the car park - what happened?

South of the Martello Tower the embayment made famous by the flags has continued to enlarge itself, and the erosion sequence has processed towards the south. At the moment it is short of eroding the deep, steep beach deposits that continue towards the mouth of the Deben ... but in the next six months .....

... the littoral cell will start to shift large amounts of material towards the South. This will add considerably to the rapidly-developing spit system there ... see  Felixstowe Ferry July 2006
