Castle Dome, One
I'm a history buff, so I've dragged my wife along to visit any number of ghost towns here in the Southwest. The best, by far, is only a forty-five minute drive from Yuma... but mostly over unfinished roads.
So Castle Dome has all three of the ideal characteristics for a tourist spot: intrinsic interest, photogenic, ... and very few tourists! 
It's a great place for "impressionist photography" - studies in form and color - with lots of old machinery... and a half-dozen bars. 
The mines at Castle Dome operated from the 186s0 to the 1970s. The museum is private, maintained by people who are passionate about preserving the memory of the region. Very, very highly recommended.
Absolutely
Particularly when a photographer with your skill is able to take proper advantage of it.
Terrific photos, especially for me, who has never nor will ever be able to visit that site - thanks for posting them.
... more to come...
Great photos. History being visited.
