Last week GeoSuffolk visited Harkstead CGS to monitor its condition - the cliff is in fine condition, but the lower shore had a noticeable covering of modern sediment. In the photograph blocks of the Harwich Stone Band litter the shore and may be seen exposed in the Eocene age clay in the cliff. Small patches of contorted gravel occur at the top of the cliff - these and other Pleistocene sands and silts may be seen at southern end of the cliff.
