Like all board members I am saddened by the loss of Jeff Nixons life and, like all responsible anglers, I applaude the highlighting of the problem of cliff collapse and the dangers of fishing such venues. With my teaching hat on, but without being an expert of our coastline from Spurn Head to Eyemouth, the main worry we face is not the collapse of some vertical hard rock cliff (like Eyemouth or Bempton) more the cliffs that not only have a hard base level but have on top the deposits of the last ice age, namely boulder clay.
Look at the headlands of Cullercoats or Beadnall and you will see sandstone topped with unstable clay, full of big rocks that we see around the high tide mark. Go to most of the Yorkshire coastline and sometimes the boulder clay is so thick there's nothing else above the tide line - this is Flamborough Head:
Further down the erosion is more severe:
Bottom line is that this type of cliff will erode more quickly than anywhere else. I feel somewhat honoured that I have lived through the formation of a new island (Surtsey, off Iceland) and witnessed the destruction of Marsden Rock. Both are relatively rare events in a lifetime. The continual erosion of clay based cliffs are not - just look at the erosion of the cliffs at Whitley Bay's pitch and putt, above the boat house.
Wet or cold weather merely increase the likelihood of an incident, so tragic in Jeff's case. Does this mean that no-one will fish these marks again? - memory is short, unfortunately, but accidents are, thankfully, infrequent. No-one will prevent anglers fishing these marks. Hopefully forewarned is forearmed.
