The Wilton quarries are owned by United Utilities and are split into two lots for sale; Wilton One with a guide price range of £30,000-£40,000 and Wilton Two, Three and Four with a guide price range of £15,000 - £25,000.
In an active discussion at the UKClimbing.com forums people are suggesting that the BMC buy the quarries www.ukclimbing.com/forums
Sounds like the BMC were taken unawares, but are now on the case.
UPDATE 24.09.07: by Guy Keating at the BMC website
"Naturally, the BMC are concerned with the potential implications of this development and have arranged to meet with a representative of United Utilities on Tuesday 25th September. Watch this space for an update after our meeting."
