This SSSI was a hive of activity on December 14th. AONB volunteers were carrying out conservation work on the Coralline Crag and GeoSuffolk was condition monitoring for the Geology Trust. The pit is on private property, but can be viewed from the adjacent public footpath as in the photograph. We told several hikers on the footpath that they were actually walking on a Pliocene sea bed! The next AONB Work Party at a geology site is March 8th - see Events page for more information.
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.
A new stone has arrived on Walpole's village green this year. it is a calcareous sandstone, quite possibly a block of Spilsby Sandstone of early Cretaceous age brought here by a Pleistocene ice sheet. It was discovered by farm machinery at a nearby farm. Thank you to the Walpole residents who informed GeoSuffolk of this specimen.
Yesterday GeoSuffolk members were condition monitoring at Newbourne Springs CGS - the Red Crag exposure, the flow of water and extensive seepage areas at this excellent site readily gained their usual GOOD condition status. And the photo? It is looking through the stream to the drifted fossil shells from the Crag carried by the flowing water.
