The lower red clay is at least 2 metres thick with no large rock
present only sporadic blue clay with
Carboniferous trace
fossils
Note this is not boulder clay !
The layer of red clay below the gravels is very tightly packed and has the odd large rounded and
un rounded rock lodged at its meeting with the gravel layer containing
Jurassic fossils mostly
Gryphaea.
The image above shows how what i think is alluvium had shrouded these older layers.
Outcrops of blue clay containing
Carboniferous plant fossils found in the red lower clay.
View showing the rough depth to the
surrounding land, but it does rise rapidly after the depth shown!
This pic shows how this bit of bank has actually already lost a lot of the soil and alluvium? that used to shroud the layers ime now exposing.
