Wow, We (as the Templeton team) dug there for several weeks the first time it was opened about 7 years ago and I thought it was too fractured to ever be made safe. Well done.
I shall be moving to a smaller house soon and need to get rid of some old Descent magazines. I have about 60+ issue 140 and earlier. The earliest edition I have is number 7. It's offered for free on an all or nothing basis. I'm in Somerset.
