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 landscape was clothed in a mild and quiet light, in which the woods and fences checkered and partitioned it with new regularity, and rough and uneven fields stretched away with lawn-like smoothness to the horizon, and the clouds, finely distinct and picturesque, seemed a fit drapery to hang over fairyland. The world seemed decked for some holiday or prouder pageantry ... like a green lane into a country maze, at the season when fruit-trees are in blossom.”
—Henry David Thoreau (1817–1862)
“Safe upon the solid rock the ugly houses stand:
Come and see my shining palaces built upon the sand.”
—Edna St. Vincent Millay (1892–1950)
