CoALEY Wood 



The large quarry in Coaley Wood is plainly visible from 

 Cam Long Down. Descending the steep eastern slope of the 

 hill, getting into the lane, and proceeding along it to " The 

 Moors," the first turning to the right leads up through Coaley 

 Wood. Soon after the lane becomes sunk, the hard sandy 

 limestone which yields Hildoceras semipolitum, S. Buckman, so 

 abundantly, and is of Lilli date, is seen projecting from the 

 bank on the right-hand side. Then high up on the left, is the 

 well-known Coaley- Wood section of the Cephalopod-Bed.
