A sandstone ‘freestone’ quarry

Ravenscraig Quarry is now flooded but otherwise unchanged and is known locally as the ‘Blue Waters’ or ‘Blue Hole’[4] because the light shining off the dark vertical faces of the quarry workings once embued the floodwater with a striking blue colour. The site was at one time a popular swimming hole however a drowning incident ended that and although rich in water plants such as the marestail (Hippuris) and pondweeds (Potamogeton the water has lost its blue colour and serves as an unofficial wildlife preserve. No rails or sleepers remain at the site.
