Millstones in the 'Slough of Despond'

The valley of the Tillingbourne in Surrey was the site of a gunpowder mill. The mill was there for a long time, and it is believed that John Bunyan used this area as a model for the Slough of Despond in Pilgrim's Progress. Only deserted buildings remain, as well as a few millstones used for grinding up the constituents of gunpowder. I love the way the super-saturated red gives an velvety feel to the surroundings here.
