Hello,
I've just bought a new book titled "The Quarries of Lakeland," by David Glover, published this year, and it mentions a plan by Burlington Slate in 2008 to open-up part of the Elterwater Quarry site - including the huge underground Peppers Quarry closehead - to visitors. At the time of publication the author states that these plans are on hold, is there any detailed news available on this project?
Cheers!
Chris
