Mill, Britannia Mine, B.C.

Just north of Vancouver, the Brittania mine houses a gravity fed concentrator that is quite a feat of architecture and engineering, as it's built on a mountainside The mine closed over thrity years ago, but it seems now that a number of different do-gooder groups have decided to "fix it up". I was there in the early '90s and fortunately, have been spared these "transformations".
