Disappearing before your eyes

The Thames foreshore is akin to a very large self-excavating trench where the ‘excavation’ takes place at irregular intervals. For the most part, archaeological digging is not undertaken as the resulting soft backfill can be a magnet for accelerated spot erosion, as can be seen where detectorists and the like have dug into the barge beds. For those of us who have worked on the London Thames since the early 1990s, the foreshore has changed significantly and in many cases, quite dramatically over the years. Surfaces, structures and deposits are either no longer there or have undergone truncation in varying degrees.

Now you don’t see it, now you do

On the other hand, in some areas the surface erosion has revealed hidden treasures, so to speak, in the form of either extensions to existing deposits or features, or structures that were only hinted at before or not visible at all, or even whole new worlds which were totally unexpected.

A word of advance warning

This state of flux in the inter-tidal zone is what makes recording at regular intervals an imperative exercise if we as archaeologists are to keep abreast of what there is to be known. On March 15th 2010, I shall be looking at the erosion on the London Thames , its various causes both in degradation and aggradation of deposits, and the resulting changes visible on the foreshore. This is something that speaks to all FROGs whether they are old hands or completely new to the foreshore – so come along and learn!
