The Rough Rock is a widespread unit of coarse sandstone which is a prominent landscape-forming feature in the Peak District and Pennines of northern England. It is assigned by geologists to the Yeadonian sub-stage of the Namurian stage of the Carboniferous period.
It is the most extensive of all of the sandstones of the Millstone Grit Group occurring throughout the Peak District, South and West Pennines and extending northwards into the central and northern Pennines.
It originated as a sheet of deltaic deposits spread across most of the Pennine Basin associated with major rivers flowing from the north and northeast.
Famous quotes containing the words rough and/or rock:
“Virtue rejects facility to be her companion.... She requires a craggy, rough and thorny way.”
—Michel de Montaigne (1533–1592)
“Nobody dast blame this man.... For a salesman, there is no rock bottom to the life. He don’t put a bolt to a nut, he don’t tell you the law or give you medicine. He’s a man way out there in the blue, riding on a smile and a shoeshine. And when they start not smiling back—that’s an earthquake. And then you get yourself a couple of spots on your hat, and you’re finished. Nobody dast blame this man. A salesman is got to dream, boy. It comes with the territory.”
—Arthur Miller (b. 1915)
