Otherwise known as Horseshoe Quarry, this extensive excavation for aggregates was once operated by the minerals company, Tarmac. Once the quarry became disused climbers were attracted to the vertical limestone walls but the quarry owner, concerned about its public liability, banned climbing though the ban wasn't strictly enforced.
Eventually the quarry was purchased by the British Mountaineering Council and has been dedicated by them as 'open access Land' under the terms of the CROW Act.
Many lines on the rock face have been 'bolted', meaning that climbers can protect themselves from falls by clipping ropes into the eyebolts - that's all the bolts are there for - they're not intended to provide material assistance in the making of an ascent!
The flat rock surface in the foreground has bolts inserted too; several can be seen easily in a patch of dark rock. These bolts were inserted by the BMC and then put under strain, some being tested to breaking point, so that the strength of the bolt and the rock could be assessed.
