Geological formations at Hobbs Quarry Location:  Noted Species: Ancient woodland species Description: Use our leaflet to explore Hobbs Quarry, a small secluded site of many interests - geology, ancient woodland species and an old lime-kiln. The three aspects were interlinked - the Silurian limestones were burned in the kiln for fertilisers, and the kiln was fired with charcoal from the coppiced ancient woodland. Perhaps rarest are the ballstone coral reef formations from seas 425 million years ago. Advice: Access is down a narrow lane (see leaflet) with parking only for a couple of cars.

East Wood Location: St Briavels, Forest of Dean Noted Species: veteran yew Description: This forestry commission site is a Nature Reserve for a rare geological feature (somewhat overgrown) the limestone pavement - features that are famous in Derbyshire, Yorkshire and Ireland. Close to the reserve stands the huge veteran tree known as "King Yew" hundreds of years old, once standing on open ground Advice: We suggest visit the Forestry Commission Centre at Beechenhurst for information about their huge veterans including the King Yew - all worth a visit and a great feature of this ancient Forest.
