Dry Hill Lane
Dry Hill Quarry. Former rag stone quarry disused and grassed over to create a public open space that has been designated by English Nature as a geological local nature reserve. It had been opened by Sevenoaks RDC as a source of roadstone in 1921. Top soil was used for sandbags in the Second World War. Ragstone was prised out and then smashed with hammers on the quarry floor but in the 1940s crowbars were replaced by explosives. The crushed stone was mixed with tarmac for the roads. The seam was exhausted by 1951 and the quarry was closed. The site and provides a classic exposure through the "rag and hassock" faces of the Hythe Beds. The faces show characteristic sediments the early development of chert. The site was famous for its rich and diverse fossils crucial for paleontological studies but these cannot easily be seen in the rock faces now showing. Feel the crumbly texture of some of the exposed rock faces - difficult to work. The variety of colours in the rock can also be seen.
