Extract

At a distance of about two and a half miles from Aberystwyth, the road leading eastwards towards Devil's Bridge curves round the north side of a small knoll on the ridge separating the larger valley of the Rheidol on the north from the smaller valley of the Paith on the south. The road here reaches a height of 400 feet and the knoll rises a further 100 feet above it. Opening directly from the south side of the road, a quarry (now disused) has been excavated in the knoll and in this quarry the Aberystwyth Grits present a very striking appearance, showing a zig-zag structure with one fold above the other.
