Berries festoon the quarry reserve

Ketton Quarry, Rutland Withered stems of white bryony lash together clumps of little red globes hanging in garlands, and hedges blush with hawthorn berries

The blazing morning sun rapidly scorches most of it away, but in the deepest still hollows of Ketton quarry the thick, white, dusting endures into the afternoon.
