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.

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. |
