The usual place to
start for a photo-shoot of Happisburgh is the destroyed lifeboat
ramp. Here the concrete has been undermined and has been left,
in some areas, hanging against the cliff. Behind are other
reminders of erosion, namely the ruined revetments and newer
rip-rap. |

From the cliff top
in front of the caravan and camping field, and the beach steps
in the centre. |

To the north the
cliffs are edging back from the line of revetments - and the
pillbox makes a good marker! |

Still in the area
of the old lifeboat ramp, and its tangled mass of concrete. |

A pronounced plinth
of clay basement has developed in front of Cliff Road, where
unglamorous buildings are about to fall. |

The shoreline still
has ineffective revetments, but also new rip-rap defences,
centre. |

The rip=rap is low
in the water in places, and its line is by no means complete,
but it is soaking up a lot of energy, nevertheless. |

old steel reinforcement rods litter the beach. |

There has been
little recession in front of cliff Road and, in places,
vegetation has colonised the less severe slopes. |

The headland at
Cliff Road is being worn back, left, but the wide expanse of
beach to the south appears to be accumulating! |

The tide was
turning when these shots were taken, and occasionally a
large wave would come over the outer beach. |

Looking towards the
defences at Cart Gap, where beach accumulation was to become
more evident. |

A deep backwater
has etched out a channel that cuts through a gap in the groyne
at the northern end of the Cart Gap defences. |

Older defences have
been swamped by an accumulation of beach material, cut
into by the lateral channels. |

Harder defences
predominate south of the access at Cart Gap, with groynes doing
a big job, left, but displaying the pressures of beach
entrapment by the need to reinforce the lee of the groyne with
rip-rap. |

Groynes made from
back-to-back sheet piling filled with concrete, left. On the
right the rip-rap in front of the concrete sea wall is being
buried by sand. |

The walk was to the
most northerly of the reefs at Sea Palling. At this state of
tide the tombolo of sand fell just short of the reef. |

On the left is the
brash-line of the last high tide on the sand tombolo. On the
right is a vehicular beach access point being filled up by
blowing sand. |

The encroachment of
the sand spilled over the dune crest to the lane beyond. On the
right sand has gummed up steps up to the sea wall. |

The steel sheet
piling at the northern end of the Cart Gap defences had been
outflanked by the sea, but had then been reinforced by rip-rap.
The latest development is the invasion of blown sand from the
aggrading beach. |

The views
northwards, towards Happisburgh, show rising levels of upper
beach and some vegetation on stable slopes. |

This theme of sand
accumulation is evident from the cliff top, if not so clearly
from the sea's edge. Unfortunately, I hit the wrong button on
the camera and lost the proto-dunes developing in the northern
part of the bay! |
