As a newbie, can someone clarify the scope of Aditnow? Is it limited to underground extraction? Are people happy with surface extraction sites being added?
From my view, it seems sensible to include some interesting 'surface' sites such as Penrhyn and the Nantlle sites as they provide 50 percent of the whole picture of Welsh slate extraction, and are just as fascinating to visit as the underground sites. But in the SE, I see there are dozens of open chalk pits listed in the database, the majority of which are lost, filled, have little interest (to me) and are a completely different sort of site to the various chalk mines and deneholes. Similarly, the sand mines in Surrey and Kent have modern equivalents of huge opencast sandpits, which last a few years and end up as massive landfill sites with nothing to see or record.
In the world of mineral extraction, chalk is as important to the SE as slate is to North Wales, yet I feel more inclined to record or read about surface slate workings than chalk pits, with a few exceptions such as Betchworth and Brockham where there are unusual remains, railways, limekilns etc.
