Associate with the nearby Westburybrook Iron Mine (aka Edgehills Iron Mine), for which a shaft entrance (now capped with a concrete surface) is sited nearby.
The quarry is sited in the Forest of Dean and provides an easily accessible exposure through c.75 metres of Drybrook Sandstone. The sandstones include good sedimentary structures and fossil traces which indicate a shallow marine environment. The Drybrook Sandstone lies between the Chadian Whitehead Limestone and the overlying unconformable Coal Measures.
