Changes to the local landscape may be sudden or take place slowly. Coastal erosion progresses (if that is the correct word) at different rates depending on the weather. Patterns emerge. Cliff edges with grass and other plants overhang the edge, before falling. Narrow flat-topped grassy areas become bare soil, being sharpened to a ridge. Sometimes a hole appears in the cliff. Then it becomes bigger, the part of the cliff above the hole collapses leaving a gap.
The photos show a small hole in a cliff, a place where a hole has become a dip, a part of the grassy top, which has collapsed a small distance and some buck’s horn plantain* on the edge.
*On a subsequent walk I realised that this is sea plantain.
A post from 2015 has photos of the same section of cliffs.
