The project to create the 110 metre walkway, called the Crag Walk, was scheduled to begin on November 22 2010. It looks as if it did indeed start on time, as a considerable number of boulders have been delivered and a majority are in place. The idea is to create a breakwater- to protect the cliff in front of Walton Tower, and to provide an observation platform to examine the cliffs themselves.

Slumping of the crag, and underlying clays, have been allowed at the Tower as the cliffs are an SSSI, and provide an endless supply of marker fossils. This scheme will, eventually, enable the cliff slope to recline to an angle of repose and, in theory, cease active headward erosion ... thus saving the Towerr.

The proximity of the Tower to the top of a considerable free-face is evident; after the frosts and rains of autumn slumping has been rapid in this first embayment north of the A-framed groyne.

A good few items of rip-rap have to be arranged into the walkway design, that should provide access to view the cliffs at all states of the tide. Meanwhile, the slumping continues. It will be interesting to observe the rate of cliff-toe removal when the schemes complete.

Towards the northern edge of the first embayment there has been considerable retreat, and this observer cannot but help thinking that the scheme will be outflanked even before it has been completed. time will tell!

The materials in the second embayment have been slumping catastrophically since my visit of exactly three months ago. Walton-on-the-Naze September 12 2010. The inclined terraces, of the rotational slumps stretch away, downslope.

The far side of this embayment has also been eroding quickly, above, and the miniature blocks have clearly been created recently as they would surely not survive more than a day or two.
