This relatively flat area above the wave-cut platform (see pin below) suggests a 'relic feature' also cut by the sea at the time of a relatively higher sea level. Such relative sea level change in this area might be account for by a small amount of isostatic uplift after the last ice age as the weight of the ice sheet that extended south to the Bristol Channel melted away.
Behind the flat area is a relic sea cliff (covered in trees) that is now cut-off from the processes that formed it many thousand of years ago. There is a similar, but smaller, 'flat' on the western side of the mouth of the River Lyn to the right of the picture.
There are other similar coastal flats along the north Somerset coast that suggest the process is repeated at other locations. Some are much larger as for example at Minehead. '
