A china clay pit between Gunheath and Goonbarrow. It is marked on older maps but in the early 1980's it was included into the advancing Gunheath. Old specimens occasionally come on the market from this location as collectors in the 1960's and 70's found it easy to access and with an obvious Turquoise vein it was a regular site to visit. Nothing can be seen of this site today.
