On the image

Somebody spent decades convinced this hole would keep paying for itself. The walls are stacked with scree the way a ledger is stacked with entries nobody wants to add up twice, and the pale scar on the right face is where a whole slope of rock decided, on its own schedule, to come down rather than be extracted properly.

At the bottom sits a puddle of the exact turquoise blue that mining engineers of the era learned to distrust, since it usually means the pumps have stopped and the pit is quietly filling in on nobody's payroll. A single loading platform still clings to the tailings partway up, built with the confidence of men who assumed the operation would need it a while longer.

Birch and gorse have already started colonizing the lower slopes, doing the unglamorous work of reclaiming the site that no closure committee ever quite gets around to funding. The rock kept its structural integrity for millions of years before anyone opened it up; it took about one working generation to leave it looking like this.

The historian's note

Slate and stone quarrying was a major extractive industry across upland Britain and parts of the Appalachians through the mid-twentieth century, with pits cut progressively deeper into hillsides as seams were followed downward. By the 1960s many smaller quarries of this type were approaching the end of economically viable extraction, as competition from cheaper roofing and building materials, and the rising cost of dewatering ever-deeper workings, made continued operation marginal.

The pooling of water at the pit floor, visible here, is characteristic of a quarry whose drainage pumps have been reduced or shut down, either seasonally or as part of a wind-down toward closure. The scree slopes and tailings piles record decades of overburden removal, while the small platform structure partway up the slope is consistent with a loading or winch station used to move extracted stone to the surface.

Sites of this kind were frequently abandoned rather than formally reclaimed, left to flood and re-vegetate naturally over subsequent decades, which is the process already visible beginning at the margins of this pit.
