Hi All,
Took a couple of pictures at low tide at Grid Ref ST 531 838 the other day, these can be found here:

Showing very old tree stumps and a peir like array, these get exposed when the gravel banks shift.
Some more information can be found here:

Please note the tides are very dangerous here and I suggest not visiting unless you have a good knowledge of the terrain and are familiar with the incoming tidal patterns.
Regs,
Mike
