on the opposite side of Minninglow to where you arrived, descend another concessionary path leading down to the High Peak Trail. Several large craters on the hillside are probably where stone was extracted for walling, whilst a quarry to the side of the trail was where stone was sourced for the incredible embankment structure nearby.
Yet more industrial heritage can be seen from the trail by looking to where Minninglow Lane disappears into a hollow where there are the remains of silica pits in what is now a conservation site. During the 19th century the deposits of high-firing silica sand found here were manufactured into refractory bricks in a brick-kiln complex to the side of the railway line. These bricks were used in the Sheffield Steel industry. Refractory bricks are still manufactured to this day, but from the Friden site of DSF Refractories & Minerals a few miles away.
