The drift that swept over the land would appear to have been from west to east, with a trend to the south, as no granite has been transported, except in the river-beds to the north or west, whereas blocks have been conveyed eastward. This is in accordance with what is shown by the long ridges of clay on the west of Dartmoor, formed of the rubbing down of the slaty rocks that lie north and north-west. These bands all run north and south on the sides of hills, and in draining processes they have to be pierced from east to west. This indicates that at some period during the Glacial Age there was a wash of water from the north-west over Devon, depositing clay and transporting granite.
On the sides of the tors are what are locally termed "clitters" or "clatters" (Welsh clechr consisting of a vast quantity of stone strewn in streams from the tors, spreading out fanlike on the slopes. These are the wreckage of the tor when far higher than it is now, i.e. of the harder portions that have not been dissolved and swept away.
"The tors—Nature's towers—are huge masses of granite on the top of the hills, which are not high enough to be called mountains, piled one upon another in Nature's own fantastic way. There may be a tor, or a group of tors, crowning an eminence, but the effect, either near or afar, is to give the hilltop a grand and imposing look.
