The heavily jointed and irregularly bedded sandstone always looked untrustworthy and a rockfall occurred some twenty-five or thirty years ago. Moss, fern and ash have colonised the jumble of boulders. The patterns of iron staining in one corner of the quarry fascinate me; there’s such a contrast between the iron concretions and the pure white lens of quartz sand. Large pebbles somehow got incorporated into a well-sorted sandbank at the time the sediment was laid down in a river or estuary 300 million years ago.
The graffiti isn’t so ancient.
