This is the Buck Stone below Stanage Edge in the Peak District National Park. It stands within its own walled enclosure, a little way down from the Long Causeway that rises up to the top of Stanage Edge from Dennis Knoll.
This large boulder was once used as a sort of transport cafe for the packhorse trains that used the Long Causeway to deliver goods to and from Sheffield. The holes in the boulder were sockets for a primitive timber shelter and around the boulder are runnels, grooves chiselled into the surface that deflected rain water away from the structure. The trains used to stop here, the walled enclosure useful for holding the ponies, whilst the Jagger, the man who guided the packhorse train, would take in refreshment and rest.
The boulder is often ignored now, being off the beaten track, but its past is of importance tot he trade routes that criss crossed the area. It has some nice bouldering problems, quite easy even for old people like me. There is a reward at the top, but I will leave it for you to find out for yourself.
