Peter - when the boundaries of the Peak District National Park were drawn up, they were drawn up in such a way as to carefully EXCLUDE the majority of quarries in the Peak District!
For example in the Matlock area, the Peak Park boundary runs down the eastern boundary of Jugholes Wood and Tearsall (which was not quarried then but a easy trip into old workings), this then excluded the opencast workings on Masson Hill, all the Matlock quarries, Cromford, Wirksworth, Middleton and the Via Gellia. The ICI ones on the Ashbourne/Buxton road south of Buxton were excluded and presumably the ones at Dove Holes north of Buxton too.
I was working in administration in Derbyshire County Architect's department at the time the Peak District National Park (the first National Park in the UK) came into being - from memory about 1948/49. I always remember the Chairman of Derbyshire County Council (the labour councillor Charles White from Tansley - he who decided in his wisdom to move the County Offices from the administrative County Town of Derby north to Matlock - conveniently on his doorstep - to the white elephant of an old Hydro i.e. Smedley's Hydro at a vast expense to rate-payers in 1956. It's been renamed as the County Hall but is known locally as the "Kremlin") being presented with a new chain of office by the Head Director of Derbyshire Stone Ltd., the main quarrying firm in the Matlock area. Being very young then I viewed this action without suspicion, but having become wise over the years it makes one think! Especially with all the then Derbyshire Stone quarries being excluded from the Peak Park. Just think of the beauty of Matlock Bath and the Via Gellia, why should this beautiful scenery have been excluded from the Peak Park? Answer - because it lay within a quarrying area.
The worse thing that happened to the Peak District was the granting of the open-ended 1952 Mineral Planning Consents which virtually allowed mineral contractors to do what they wanted. Thich was okay in those early times with much more manual labour and smaller machinery involved, but with the hugh machines and less labour intensive quarrying methods of today, these very old original planning consents are flaunted and used by present day quarry firms within the Peak Park to wreck havoc, which is the reason for many of the battles one has seen in recent years i.e. Great Longston north of Bakewell etc.
Quarrying has always been a major business in the Peak District and always will be whilst the rest of the UK want buildings, roads constructed, coal fired power stations, sugar beet factories etc. It was one of the main industries of the area and provided work and wages long before the Peak Park became a tourist attraction. Luckily when I lived in the Peak District (a slightly different geographical area than the Peak Park) I lived just outside the boundaries of the Park, so I was able to enjoy the Park without the restraints of living in it.
A while ago it was planned to give National Park status to the New Forest in Hampshire to the west of where I live now. There was a lot of discussion and many people wanted to live within the boundaries. Since then the New Forest has become a National Park and quite a few people have become disillusioned about living within one.
