The state of the ride denies access to the northern beach to a group on a school fieldwork trip. The beach has been considerably lowered here, but will soon form the basis of 'Crag Walk', a 100m breakwater that will offer views of the eroding cliff from seaward at all states of the tide.

Some views that will change considerably when the rocks arrive for the breakwater, that will cut off the wave action that currently removes the toe of the landslips from the slumping cliffs.

Recession rates should reduce as the slumping materials piles up against the barrier, and then, of course, the free face will fail until an 'angle of repose' is achieved!

The free face of the cliff in this first embayment has grown over the previous several years, and allowing it to 'relax' will inevitably lead to the loss of the cafe, if not the Tower itself.

Signs of impending  recession to the north of the first embayment, with material ending up in debris flows, often saturated mobile flows.

A look back to the south, left, shows the considerable height of the free face, whilst to the north rotational slumps, with blocks large and small .. and some quite delicate, are on the move.

The coastline is about to retreat! Taken from several fissures out from the edge, these blocks are about to move .. just awaiting some rain I expect!
