The development of 'Crag
Walk' appears to be almost complete, from the engineering point of view.

Only one area
appears in need of finishing off, and that is the toe of the
promontory. |

The free face of
the cliff continues to increase in height as the slumped mass
below accelerates towards the shore. |

Further north there
have been fresh cliff falls, left, and a mass of rotational
slumped blocks. |

The new viewing
platform built over the beach, is seen behind the descending
mass. |

The flows are quite
mobile at this time of the year and, without drainage of the
new, relaxed slope, I doubt the tower will be saved for long. |

One fear for this
scheme is that it could simply be overwhelmed by mobile flows
coming from an unstabilised cliff. |

The height of the cliff and
its past pattern of mass-movement are all a matter of concern for the
protection of the Tower. |

The trench between
the cliff and the structure of 'Crag Walk' will fill up with a
morass of slumped material. |

Construction is
almost at an end, with just the northern end of the
construction, centre, needing its finishing touches. |

The digger is
carefully repositioning stone and gravel on the landward side of
the promontory. On the seaward side it can be seen, even at
mid-tide, that there will be no beach. |

The seaward slope
of 'Crag Walk', from the rip-rap near the A-frame breakwater,
with Felixstowe cranes in the background. The new structure and
lower slopes of the cliff should be clearly visible from the top
of the Naze Tower. |

The Mabel Greville
breakwater has been severely damaged, on the Tuesday and
Wednesday before Christmas, 2010. As there was no storm, just
very cold conditions, it might have had something to do with
frost damage, as rare as that might seem. Can't blame local
youth for this, anyway! |
