Hi Graeme,
Bedlam Furnace looks fascinating. I love stuff like that. The ghost towns book looks interesting too. There are several ghost town books available here in the U.S.
I've done a bit of ghost-towning myself -- in addition to what's included in Voices on the Prairie. If you go to
http://www.russ-lewis.com/photo_gallery/selector.html you find an index that includes a bunch of picture categories. Western Ruins of the Sixties has a bunch of ghost town stuff in it, as does the Colorado category, though both are combined with other things. In 2006 I made a couple several-day trips through southern Colorado, New Mexico, Kansas, and Texas, and produced a collection of pictures I titled "For the Wind Passeth Over It." Between the shooting I did in the sixties and the 2006 trips, I managed to capture a lot of the dying history of the West just before it disappeared.
Altogether I've spent many, many days in the Colorado gold camps: towns of Cripple Creek and Victor, and the almost vanished town of Goldfield, which is across the road from Vindicator Valley, where the Vindicator mine was located -- one of the early mining bonanzas. My youngest son, Tom, did a video on Vindicator Valley -- at least part of it -- with a drone. His video is at
