I went there with my 2 year old last weekend, an invite from the curator of the museum and author of Bamberton: From Dust to Bust and Back http://books.googl...EACAAJ&redir_esc=y . She gave us a private tour of the whole area, including into the actively used parts. Got some amazing pics of the quarry too. They're importing cement from ships from the mainland and transporting it through Bamberton and out. Pics and story will be up on the Haunted BC facebook site some time after I finish my Bridge River Valley trip photo sets.
Nice pictures, I didn't manage to discover the locations shown in 4 and 5. I was a little intimidated by the number of gates and cameras at the entrance, didn't stick around too long, but those foundations of the old buildings make for a nice photo op!
