This large excavation on the banks of the river leven just north west of leven bank, seems to show the same red alluvial deposit as at Stainton and all other locations i have excavated at various sites in the south west area of Cleveland, north east England.
I am not sure what the project is yet maybe a bridge, but the superficial deposits are in my mind certainly not boulder clay.
This image shows what i believe to be Triassic mudstone amongst the red clay, as it is found 3.5 miles south east at Stainton as well as at all other locations Ive excavated , in the south west area of Cleveland.
