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:
“The last and greatest Herald of Heaven’s King,
Girt with rough skins, hies to the deserts wild,
Among that savage brood the woods forth bring,
Which he than man more harmless found and mild.”
—William Drummond, of Hawthornden (1585–1649)
“When we were at school we were taught to sing the songs of the Europeans. How many of us were taught the songs of the Wanyamwezi or of the Wahehe? Many of us have learnt to dance the rumba, or the cha cha, to rock and roll and to twist and even to dance the waltz and foxtrot. But how many of us can dance, or have even heard of the gombe sugu, the mangala, nyang’umumi, kiduo, or lele mama?”
—Julius K. Nyerere (b. 1922)
