You should be able to check all her claims on GE and the imperial might work.
I don't believe that hill forts are iron age , they predate by a long way and why would you build a fort in the most inaccesible place in the peak district with no water supply. They are megalithic constructions and usually quite flat topped/ levelled as at Old Sarum. they are often located on meaningul azimuths from the stone circles in the location. They are often very close to ancient trackways such as the Ridgeway.
