gruffy-ground
n.— «But here and there, as at Charterhouse, Priddy, and around Shipham, the “gruffy-ground,” as it was called, survives. Although wild flowers in great variety blossom on it, and heaps of soil and stone turned over by the miners have become cushiony seas for picnickers, it remains land with an unnatural look—land that even now seems in turmoil, and an impressive monument to the immense energies of men in the long ago.» —“Mendip’s famous centuries-old lead mines” by Jill Bailey Weston Mercury (United Kingdom) May 9, 2007.
