Ancient sediments and Stainton gravel beds.

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.
