Northumberland's sleeping rainbow
The photo above is of a rock below East Woodward Crag in Northumberland. A corner has been chipped off, revealing the bright pink rock that lurks beneath the dull brown of its weathered, lichenous exterior; as surprising as finding a toad estivating in dry desert earth.
It reminded me of the formerly sooty facades of Glasgow's sandstone buildings, almost all of which have now been cleaned of their industrial grime. If the same sandblasting treatment were to be applied to the sandstone outcrops of Northumberland, that hibernating rainbow might be reawakened, dazzling the visiting climber with desert hues reminiscent of the American southwest.
(Note to local ethics police - I am not seriously proposing that any crags be sandblasted)
