So called because the crag is in an ecologically sensitive area and publicising details about its location is not allowed under the access agreement.
The crag was first discovered by Tom Proctor and Martin Boysen [1]. In the late '80s it became a forging ground for brick-hard moves, with some of the hardest problems in the world at the time established by Jerry Moffatt and Ben Moon.
