The most significant feature of this series of c19th exploratory workings (which on successive maps from the late c19th onwards, are only ever listed as ‘quarries’) as seen from the Pennine Way/Teesdale Way, is a barred adit (tunnel). Iron (siderite) and zinc (sphalerite) deposits had been detected in the Single Post Limestone between Wynch Bridge and Scoberry Bridge however limited quantities and restricted access seem to have undermined the commercial viability of the workings. Apart from the main level, which is supported by pine timbers, there are two side tunnels plus mature spoil heaps.
