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.

A landscape of boulders!

Groynes and a somewhat stony beach to the south of the A-frame breakwater. left, and right, a sand and shingle beach just north of the Mabel Greville breakwater.

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!
