The Shore Below the New Sea Wall (Part 1)

The shore beneath the new sea wall in Lyme Regis looks very different now the old breakwaters or groynes have been removed. You can still see the linear concrete footings of the old wood and iron structures but most of the pebbles and cobbles that used to accumulate between the walls are now absent (at least for the moment). A bare rock pavement is revealed, comprising a series of steps representing the strata and colonised by seaweeds. Rippled sand sometimes deposits in the valleys between the rock ledges.

  1. Thank you, John. LR6 shows the surface of Liassic limestone. I think this is the stratum that has large ammonite fossils. The undulating surface may be caused by weathering erosion but it could be the original buried surface because the other exposed rock layers do not have that pattern and texture. I’ll look for some more images of it that I took on an earlier visit to see it I can find out more.

  2. The new sea wall and walkway has made a big difference to that part of Lyme. There seem to be some interesting insect colonies developing on the cliffs, perhaps they were always there?

  3. As more flowers take hold there will be more insects of all sorts but the softish cliffs are very good for mining bees and last spring when I was at the bottom of the walkway I saw a largish colony of hairy-footed flower bees in the cliff but couldnt get close enough to photograph them. A camera with a better zoom might do it.

  4. Thank you, Philip. I shall keep my eyes open when I next visit, especially when I use that path and steps leading down from the car park at the top of town down to the sea wall walkway.
