When the colliery closed, the spoil heap of Princess Colliery was planted with trees to stabilise the slope. Since then, the trees have grown up and been joined by many “self-setters”. The trees are now being thinned.

This photo, taken from Yorkley Wood by Robin Phelps, shows the valley of the river Lyd enveloped in fog with the top of the Princess Royal spoil heap above the top of the fog. Bream (top left) is in sunshine.

This photo, a detail from an old postcard, shows the spoil heap before tree growth had become established. Park Hill is in front of the spoil heap.
